Pros: "Good experience"
Cons: "Better snacks"

Pros: "Nothing."
Cons: "Flight was delayed 2 hours. Even though I had carry on, they checked it and this made me waste my time at baggage claim rather than gate checking. Flight attendants were miserable. Power supply didn’t work at seats."

Pros: "Take off on time, arrived early, pleasant flight attendant"
Cons: "Had to sit on tarmac after arriving early"

Pros: "Clean plane, the seat felt roomy. Smooth ride and the captain communicated clearly."
Cons: "It felt super hot and I wish there was food included in such a long flight."

Pros: "Quick flight"
Cons: "Flight attendant spoke like a robot. Could not understand her."

Pros: "On time"
Cons: "Small aircraft"

Pros: "On time, pleasant and friendly flight attendant, no unexpected issues or problems."
Cons: "Grumpy gate attendants at YUL! Could not hear the captain’s comments over the PA system. Shouldn’t the volume be checked every so often? We were offered only water or coffee, bad enough, then there was no milk or cream on board, so water or black coffee... not very impressive! And there was no entertainment so I’d rate that zero but the scale only goes as low as one star."

Pros: "Staff, service, options"

Pros: "As usual great staff and awesome entertainment/connectivity"
Cons: "Due to weather & maintenance flight was delayed for IFR release & fuel temperature gauge issues. Staff was very helpful. Would have appreciated a drink voucher. Some unprofessional passengers took their frustrations out on the flight attendants."

Pros: "It's a fast flight and boarding was quick."
Cons: "The terminal at LGA airlines is terrible."

Cons: "Customs never to hire more agents to work in the early mornings."

Pros: "On time, and pleasant flight. Flight attendants were first class: very competent."
Cons: "I slept all the way, so can’t say whether anything went wrong with the flight."

Cons: "Not much to read"

Pros: "Crew friendly"
Cons: "Middle seat with no option for me to move"

Pros: "Movie"
Cons: "Break downs again... At least this time they found another plane."

Pros: "Flight attendants were pleasant."

Pros: "Friendly service, comfortable seat, on time, no issues."

Cons: "Everything"

Pros: "The crew was great"
Cons: "The flight was 4 hours delayed"

Pros: "I flew on a basic economy fare (I understand the restrictions) and was seated in Economy Comfort +, so that was appreciated."
Cons: "I could see on the Fly Delta app that I had been placed in seat 10B, but neither the app nor my boarding pass gave me a group to board with, so I assumed that I needed to board with group 3, which necessitated gate-checking my rollerboard bag. Only when I approached the gate to board did I notice on the info screen that I had been "upgraded" to Comfort + and granted boarding with the Sky Priority group. I wish this had been clearer so I could have avoided waiting to board and gate-checking my bag. Minor inconvenience but room for improvement on Delta's part."

Pros: "Over all everything specially we got in earlier than expected"

Pros: "Friendly staff and comfortable seating"

Pros: "This was not my original transfer flight but everyone was much nicer and helpful than serious and being rude. Love Delta, I did not flight United because I wouldn’t have met my United flight once landing in ATL. The Young African American woman who was at the gate was amazing and so reassuring that I would make my flight to Chicago. Would book Delta, just because of how nice she was to me."

Pros: "i liked that staff and crew were very communicative and pleasant."
Cons: "one crew member didn't show up and caused delayed flight."

Pros: "Crew member Lori was exceptional. Great detail to safety and customer service!"

Pros: "Flight was on time. Boarded quickly with no fuss."

Pros: "I got upgraded to comfort + which was great. quick flight, was even early"

Pros: "Flt on time, very nice and friendly gate agent and flight attendant"

Cons: "Too tight and seats not comfortable."

Pros: "Fligth were on time"
Cons: "My flight from Montreal to Atlanta was 2:30 min Left at 6:10 arrive at 8:30 roughly Tried twice to get to my connection earlier and get 9:30 instead of 12:09 fligth to Daytona Delta was not flexible to allow me to book saying i did not have 55 min in between fligth which i had than lear n it will cost $75.00 to change the fligth - What? Very disappointed of Delta - lost 3 hrs at the airport today"

Cons: "Delayed"

Pros: "The Delta people were solicitous, efficient and brilliant the whole way through. We had not a bit of trouble. Our first class seats were comfortable, but with the supplied blanket, pillow and poor air conditioning it was a hot flight. The cabin personnel were wonderful as per usual, and my tasty gin and tonic soothed any discontent. I wish I could fly this way all the time!"
Cons: "The private contractor handling wheelchair assistance was terrible. A Delta employee theorized that they do not pay enough to attract and retain personnel. Our pre-arranged chair was not there, multiple calls by our Delta assistant finally got us a ride to the chair holding area, but after about 45 minutes we gave up and shuffled off to the security area on foot. Thank goodness my hubby is mobile enough for that to have been an option. When we abandoned our wait we were still 4th in line for an attendant to push the chair. If Delta has any responsibility in this it would be in the retention and compensation for the private contractor."

Pros: "Same as above."

Cons: "The delta studio didn't work with Android 8"

Pros: "Couldn’t find a thing."
Cons: "My husband booked West Jet by phone. They spelled my name wrong on the ticket which caused hours of delays tryng to check in...ultimately leading to our missing the flight. The time spent was around 6 hours....4 of them the were on one continuous phone call where we were bumped back and forth between West Jet and Delta. The problem was never fixed and we haven’t flown home yet. We have new flights booked on Delta but only because Delta took pity....West Jet does no refunds or reticketing. If flights are missed you're out on of luck!"

Pros: "We were traveling with a toddler and infant but put in different row because the tickets were purchased separately. Gate staff promptly put us together and even bumped us up to delta comfort. Was a very pleasant trip. Thanks delta!"

Pros: "Ease of flight"
Cons: "N/A"

Pros: "Plane arrived early"
Cons: "They board the front of the plane first, meaning the aisles get clogged up slowing down the process. Also, staff kept insisting pre boarding that more people needed to check their bags because there wasn't enough overhead bin space, but there were plenty of bins not full by take off."

Pros: "Accident on way to airport, so I showed up to check bags 45 minutes before flight time. They said they couldn't get the bag to the plane..in 45 minutes? So, they put on the next flight... 6 hours later. Said I could fly without the bag... uh, no thanks. They would not look for alternatives without charging me more. Flight attendants were crabby, otherwise everything was fine. I flew British Airways a few months ago. Night and day. Seriously. Delta does not even approach having good service. There was no comparison to British Air--- Delta is not in the same league."

Cons: "Seats are very small."

Pros: "Entertainment options weren't bad. Most of the crew was polite other than one flight attendant who seemed ambivalent and unhappy to be there."
Cons: "Three hour+ flight and just one tiny bag of pretzels? And no lemon or lime wedges on the beverage cart? Plus, I have to pay extra for one checked bag. I will only fly Delta if I have to in the future. Subpar airline."

Pros: "What I liked: Sky Priority privilege came with separate luggage check-in queues and early boarding"
Cons: "What I disliked: Seats were too small No beverages or snacks offered No USB or power outlets available Three different groups board before Delta Comfort (e.g. those needing more time, travelers with children, first/business class) Didn't see the value compared to a less expensive main cabin ticket"

Pros: "I was notified about the delay via text before I left for the airport, which was nice. I would not have checked my email."
Cons: "Delayed for over 2 hours. I have never flown Delta before this flight and it wasn't a great representation. The flight attendants were nice but I was in a seat near the engine and it was making really weird noises. I fly almost every two weeks, so I'm used to engine noises but this was one of the loudest/most rickety sounding flights I have ever been on.. and I have flown Spirit a few times. It just didn't feel safe. Landing scared me a little too as I have landed in O'Hare countless times and have never flown so low to the highway upon entry. It felt like we were only a couple hundred feet above the cars."

Pros: "Great short trip with an attentive crew."
Cons: "Seats were a bit uncofortable and small compared to previous flights."

Cons: "The flight attendant looked like she was mad throughout the whole flight"

Pros: "We were delayed due to weather and Delta brought a cart of snacks and drinks over to the gate for us."

Pros: "Everything went well"
Cons: "I was late from first flight"

Pros: "Plane got to NY."
Cons: "Plane got to NY an hour late due to a maintenance issue, and we missed a connection because of it. Delta staff very unhelpful regarding connections and rebooking... we got redirected to a wall of phones to call for help."

Pros: "Nice crew"
Cons: "Computer glitch at boarding"

Pros: "Punctuality!"

Cons: "Flight were delayed abnd canceled"

Pros: "Good food and great crew!"
Cons: "Being 6'2" is the worst when traveling economic."

Pros: "Food was good , very comfortable seats and the time we departed to the time we arrive I will rate it 10 out of ten I felt as if I was on a 2 hours flight . It’s was just one of those wonderful BA flight I can’t forget"
Cons: "It’s was just the hassle to get from Terminal 5 to Terminal 3 with luggage but made it all in all"

Pros: "Friendly staff. The food was Ok. The flight was on time."
Cons: "My onboard entertainment system's headphone didnt work. I Was told there is nothing they can do about it, which is fair enough, but i dont think it was fair on me. People kept bumping into my shoulder but i guess there isn't much that can be done about it."

Cons: "increasingly reducing space. person sitting next to me overweight and made it uncomfortable for me during the entire trip."

Pros: "The crew were super helpful and attentive."
Cons: "Food was not the best, the leg room was ridiculously small and the entertainment system had some issues, but all in was a nice trip"

Cons: "Connecting flight experience - Had to wait in a line for around 5 hours just to speak with a customer service representative at the London airport because my previous flight was delayed and I had missed my connecting flight."

Cons: "My main issue is that I wasn't adequately informed that it was a codeshare and that I could choose my seats ahead of time"

Pros: "The crew The nice and friendly staff at the airport"
Cons: "Assigning one luggage per traveller"

Cons: "Should have more room on international overseas flights"

Cons: "My baggage was lost. This is ridiculous."

Pros: "Food. The chicken makhani was tasty and food overall was good"
Cons: "Dirty aircraft Tired crew Glitchy entertainment Slowest of boarding Super slow service Overall a disappointment"

Pros: "Just the right amount of flight time and arriving early in the morning. Dreamliner makes the flight much easier. Always get either 3rd or 7th row seats with window bed and free access to isle."
Cons: "Usually starts late sometimes in London, and always on some remote gate."

Pros: "We had a ton of extra leg room"

Pros: "Left and arrived early"
Cons: "Twice requested water that never came. On landing, the plane swerved and felt like it dipped to the right before straightening out. a little unnerving."

Pros: "Wonderfully professional crew. They made the flight very smooth and efficient, and I'm grateful for their hard work and high standards."

Pros: "AA has domestic US mkt. monopoly - they don't care to improve. People will not stop traveling so take them for suckers!!!"
Cons: "On flight service"

Pros: "Our original flight was delayed an hour, then 4 hours, then eventually cancelled. The last gate crew gave us no updates other than saying it was being delayed to a maintenance check. We eventually had to rebook our direct flight from ORD to CDG to then ORD to LHR and then to CDG. Because of this delay we missed most of our first day in Paris. The flight crew from LHR to CDG was very polite and friendly! I will be doing business with British Airways again in the near future. I will not be doing business with American Airlines anytime soon. Neither will my friends and family once they find out about my horrible experience with their lackluster customer service."
Cons: "Everything that involved American Airlines and my 7 hour flight delay."

Cons: "entertainment system crashed 1-2 times; screens to small"

Pros: "I'm alive and i eventually arrived at my final destination."
Cons: "50 characters is too few. the check in crew made me miss my flight."

Cons: "we had to take a tram >5 min to plane out in middle of runway and then we sat on the plane for >1 hour"

Pros: "I go good service in London with the assist. I liked my seat. All the crew were very helpful. Seat was okay and my travel companions were okay also. The flight was late on arrival in Chicago. But they had wheel chair assist and a nice girl Veronica that stayed with me until I got the shuttle to the Reniassance Hotel in Chicago. Great room and comfortable. Nice to have the dinner and breakfast coupons. I got assist to the airport in the van and help boarding my plane to El Paso. I give British Air ways an excellent star."
Cons: "Just the overnight but British Airways made it fine."

Pros: "The staff was wonderful and went out of there way to make me comfortable"

Pros: "I bought this flight last minute to surprise a family member for his 60th birthday – a very long trip to make for just a weekend. British made it much more comfortable though. The food was actually tasty, I might even say, and the flight attendants were very pleasant. Lovely to see that they're still flying the 747 – those big birds are disappearing too fast."
Cons: "In economy, there are still no A/C power outlets! Come on!"

Pros: "Stewardess was very pleasant and managed youth group behaviors well!"

Cons: "Flight was not through British air. Terrible system of sharing tickets you have. Finnair to AA. Cancelled on the way out and delayed and total incompetence on the way back. Never using you again. I will spread the word."

Pros: "but few are excellent. This one came close. The ticket agent for American Airlines at FCO/Roma was excellent. Altho this flight was 'billed' as a British Airways flight, it was operated by American. A little confusing when one thinks they are ticketing on a specific carrier only to be 'baited and switched' to another. That said, the equipment was in great condition, the video worked during the flight, the movie choices were very current. The food was airplane food. What more can one say."

Cons: "8.5hr flight and NO individual entertainment units"

Pros: "The temperature was warmer than I would like to experience. Our stewardess was very professional and dealt with a passenger that complained about his food."
Cons: "Choice of movies and music were not my choosing. The easy listening music has talking that I don't want to hear...for sleeping, "tick tick, tick"; "close your eyes"; I just wanted music!!!! An option of Christian music would have been nice and the Country music options were poor."

Pros: "I was pleasantly surprised at being upgraded to business class. First time I ever slept horizontally on a flight! Food was great as well."
Cons: "The seats between me and my neighbor could have had more privacy i.e. a partition so I didn't have to disturb him by watching movies as he slept. Also, had to jump over sleeping people to go to the bathroom as the extended bed did not give much room to walk."

Pros: "Comfortable plane"
Cons: "Seated too far back"

Pros: "Food was pretty good and a overall enjoyable flight. Great selection of movies and games. Made time go by faster."
Cons: "Service was a little slow and the tv was old and had a small screen although the movies were great. Also the flight delay caused me to miss my connection."

Cons: "Over a 3 hour delay from original scheduled take off. A dinner voucher given too late in the delay. I had already eaten by 8:45pm.... Once boarded, the lights stayed on in the plane to accommodate a dinner service at 11:30pm. Way too late!!! The TV screen did not work properly."

Pros: "Our flight was 3 hours late coming & going."
Cons: "We were on an older plane that didn't have individual entertainment options for the customers. That was a bummer."

Pros: "it was very nice . I will trying to stay with you for long time I'm business"

Cons: "There was no information to inform me that my flight was with American Airlines not British Airways.I hope that in the future the email will explain in detail that you will be flying with American Airlines."

Cons: "Had a few issues w online check in & no one to help. Had over $900 in pending transactions due to check in issues & no one to help, had to wait & hope they did not go thru...nor could I use on vacation I was going on"

Pros: "Comfortable seats. The plane was half full."
Cons: "Iberia makes you pay if you want to choose seats. Scarce food. Boarding was caotic."

Pros: "Good movies/entertainment"
Cons: "The food was not good. British Airways has good food, but this was Iberca (spelling?) which did Not have decent food. Also, we waited on the plane one hour before it finally took off.."

Pros: "The food, entertainment and crew were all very good. The plane was clean and water was readily available. I would choose BA over American next time I fly to Europe."
Cons: "I was switched from American to BA without being told prior to check in, the flight was delayed and no one wanted to expedite me and my 2 children getting off the flight in Chicago in order to make our connection which we ultimately missed. AA in Chicago switched me to United airlines and they charged me $75 for baggage. It was a series of unfortunate events, however I was out of pocket extra money due to a delay by British Airways."

Pros: "Left on time. Quick refreshment service."
Cons: "A little snack, like a cookie or similar would be great. Off course there was no entertainment on the short flight hence the rating."

Pros: "Nice Staff"

Pros: "Free upgrade to first class!! First class lounge, champagne upon boarding, lay down seats, peace and quiet!! Best flight I've ever been on!"

Pros: "Flight Attendant were very nice and the service was great. Good selection of movies and entertainment. Our flight was delayed but they kept us very informed about boarding and when we were scheduled to depart."
Cons: "They ran out of pasta so there was no meal choice. Also the snack served before we landed was a chicken salad sandwich which no one in my party of 5 likes."

Pros: "The entertainment was so rigid. One did not have control over the content to watch"

Pros: "Good flight and good pilot ."
Cons: "Food was cheap and not taste good.I was not able to wach any movie on my flight due not working properly monitor ."

Pros: "Everything was as good as I could hope for on an economy flight."

Pros: "Nothing.. Absolute joke!! Called me once in the a.m to say my flight had been switched to a different airline completely and delayed by 2 hours. Luckily i went to same airport same time as orgininally planned. Upon arriving i was told i would be getting om a flight to Philly instead 1.5 HOURS EARLIER than my orginal flight. Therefore i was rushed and had no iternary, check in or information from both Kayak.com or Ba,Aa. Will not book with you again!! American Airline flight staff were very ignorant, rushed and rude. Horrible first experience."

Pros: "Boarding and seat assignment process was very good. Hostess(es) and boarding crew were courteous."

Pros: "Our flight attendant was very polite and with a great attitude."
Cons: "The pilot arrived late because he went for a Tim Horton's coffee (I know that because I was in first row and I heard the flight attendants talking about that). Then, after he finally arrived with a tray full of coffees, there was an issue with the jet's computer and had to reset it and we had to wait even more. When we finally arrived, our Gate was taken by other plane already and we had to wait (more) for the first one to be available for us. Then, when we finally got our Gate, there was another issue, now with the "finger". They weren't able to move it and connect it to the plane to get off of it. So we had to wait AGAIN. And finally as soon as we got off the plane, they were supposed to give us our carry ons on the aisle (Because it was a small plane CR700) , but again, we had to wait almost 10 minutes so that they could send the luggage... To make things worse, I had a first class ticket and I couldn't get the perks of it at the airport. Because they said I wasn't flying in an international flight. Come on?! Canada->USA->Mexico is not International??? You lost me AA."

Pros: "Flights were on time."
Cons: "Seats are too small."

Pros: "Seat upgrade."

Pros: "Great surprise at the end of a long travel day. New plane, great crew."

Pros: "Nothing"
Cons: "Flight was late and caused me to miss my flight to Dallas."

Cons: "Missed first connecting flight because American Airlines wouldn't allow me to check in online due to having a toddler in my party. Had to pay for next day transfer. $240 a person. Will never use American Airlines again!"

Pros: "We liked the effiency and politeness of the staff. We enjoyed the movies, the food was better than normal."
Cons: "We were very unhappy at having to pay extra for our seats after we had booked the airfare. Especially on the way to Paris when there were so many extra available seats! I counted 50 available seats!"

Pros: "Cerainly boarding is easy and the seats are quite comfort in business class."
Cons: "the service, considering this was the highest level of service on these flights was less than I would have expected"

Pros: "First class on TUS to ORD flight - very good flight attendant who was very pleasant, attentive and knowledgeable... she remembered which drink I was having."

Cons: "Horrible long delays."

Cons: "The seats were so close together! I was between two men, and one was spitting tabaco into a cup. It was terrible."

Cons: "Not much offered on domestic flights."

Pros: "I wish I could remember the names of our flight attendants- but they were wonderful and really took time to get to know passengers! They were so friendly and went above and beyond in any of our requests. Loved them!"
Cons: "It would have been nice to have individual screens for such a long flight, but I wouldn't say that's a complaint. The flight was fine."

Pros: "Nothing"
Cons: "Personnel; lack of customer service"

Cons: "Kayak repeatedly listed the departure gate as D36 when it was D17."

Cons: "It was cancelled"

Cons: "The tsa in chicago was very unorganized. The tsa workers were extremely rude."

Cons: "Flight connection was too close. Delays in leaving Nairobi made us almost miss this flight"

Pros: "On time"
Cons: "Very cold on board"

Pros: "Was able to store my carry on and arrived early"

Pros: "Having flown long haul with American numerous times, this time I was pleasantly surprised by several things. Firstly, the brand new plane with excellent in-seat entertainment choices, power points at every seat, more comfortable chairs with better head rests and even window dimmers vs. window shades, allowing you to look outside the whole flight. Secondly, the food was much improved...definitely better quality and tastier than typical airline food. And thirdly, better service from flight attendants who actually smiled. Keep up the good work. This represents a real step change."

Pros: "The food, entertainment and crew were satisfactory."
Cons: "I did not like that my original flight was flat out cancelled. It made for a stressful trip."

Pros: "Flight was on time"
Cons: "There was water dripping from the vents. When I tried to inform the flight attendant, she shut me down so fast I couldn't believe it. All she had to do was reassure me that it wasn't a safety issue. Her attitude was like she was tired of telling passengers that it was perfectly normal. Very unprofessional!"

Cons: "Allergic to cat/dog dander. Had dog with no kennel in window seat of my row. I was on aisle seat. As we all got up to let the owner go to the bathroom a dog followed walking on my seat. For the last hour and a half of the flight the dog Sat on the owners lap. My allergies and asthma begin to flare up prior to landing . Not a pleasant flight ."

Cons: "The flight was cancelled, there is nothing to rate except the inconvenience it caused me and my fiancee who were traveling back home for a business meeting."

Pros: "Flight crew was excellent."
Cons: "We booked flights through British Airways but flew American Airlines. The check in process was a stressful mess: we were forced to stand in long customer service lines both on our first flight from LAX to Chicago and again during our very short layover in Chicago to Dublin to ensure that our bags were checked all the way to our final destination. Very stressful, and it didn't help that the gate crew was extremely rude and unprofessional. It is very inconvenient that we could not choose our seats beforehand."

Pros: "Individual entertainment. Wowww!"
Cons: "Seat was a bit tiny. Free food snacks were not quite good."

Pros: "Great staff and leg room/comfort. Food, drinks and entertainment was superb! Comfortable Boeing 787."
Cons: "Nothing"

Pros: "When the arrival time of the connecting flight was changed, we chose another set of flights."

Pros: "wifi was great"

Pros: "Clean plane . excellent staff"
Cons: "Nothing."

Pros: "Flight on time."

Pros: "Awesome crew. Comfortable seats. Great entertainment options. Good food."

Pros: "Nice crew. Chairs were comfortable."
Cons: "Not enough movies! No individual screens. Plans had dirt stuck all along the air vents"

Pros: "Fast check in, timely take off & arrival Excellent and friendly service"
Cons: "NA"

Pros: "One of the crew members, Walt, was amazing."
Cons: "Everything else was a NIGHTMARE. We bought our tickets in Nov. I paid for an upgrade and assigned seats in FEBRUARY. We flew May 13. Not only did they RESELL and REASSIGN our seats to someone else -- we could not get a refund for the upgrade we paid for. To add insult to injury, the only seats they could give us were in the back of the plane next to the toilet. Having heard so many similar nightmare stories about American Air I can say I will never ever fly American Air again. We now have to spend our firrst few days home from vacation disputing that charge, writing letters and making calls to get that damn refund. I will be sharing my discontent far and wide. Whoever at corporate thinks it's best practice to sell and sell and sell seats and live with the aggravation of the customers has an upside down notion of how to run a successful business. NIGHTMARE."

Pros: "Left and arrived on time. Crew was friendly and professional."
Cons: "Passengers are packed in like sardines. All carry on bags must be checked at the gate as the overhead bins are too small to accommodate anything except a small personal bag or jacket."

Pros: "Flight was fine"
Cons: "After traveling on 9 flights during a 2.5 week period, this crew mishandled my bag leaving damage to the handle and top of my bags."

Pros: "The staff were very friendly and informative"
Cons: "It felt a bit cramped, but overall nice seats and movie screens"

Pros: "Arrived early. Smooth flight."

Cons: "The flight attendant was arrogant. This is her job... just for $$$"

Pros: "The in flight entertainment was perfect, new, and relevant. I also had an empty seat between myself and another passenger so my legs weren't as cramped."

Pros: "My flight was very short. It was a straight flight and there was no turbulence. Flight pulled off when it was supposed and early landing."

Pros: "Nothing"
Cons: "Delayed flights, rude agents, no pre-boarding for families, no stroller delivery at the arrival gate and 20 year old planes with mechanical issues. Nightmare!"

Pros: "10 hour flight with entertainment system in main cabin that had no sound. Made the flight feel a lot longer."

Pros: "The gentlemen from the wheelchair service who was there to pick us up when we arrived in Heathrow went above and beyond his duties. Instead of passing us over to another wheelchair attendant as we needed to switch terminals, he stayed with us thru the terminal change until we were on the airplane. We needed to get our boarding passes at Heathrow from a different airline and he helped us with this. Kudos to him!! The attendants on this flight were very helpful when my husband was having a diabetic reaction and I was vomiting form air motion sickness. We were a mess!! However the flight attendants were sure we had a wheelchair in Chicago and helped us with our bags as we were exiting the plane. Nice Job"

Pros: "Nice plane, very friendly pilot."
Cons: "Delayed flight."

Cons: "They had no record of this portion of my trip, after a few people checked they found the Chicago to Ammon part so they added me onto a flight from Washington to Chicago. All should of went well from there but they sent me to the wrong gate. Luckily I just made it to the correct gate for boarding. Upon arriving at Chicago there was no one available to provide information on how to get to Royal Jordanian gates. Also on my AA portion of my flight coming into The U S in New York the flight was cancelled and I was told the next flight Available was next day (18hr delay) at the other NY airport. I had to have someone drive from D.C. (My destination) to pick me up"

Pros: "The crew was friendly and did their best, the flight took off my schedule"
Cons: "They didn't have individual tvs which was disappointing but showed three movies instead on screens. They announced the movies being shown on the flight at the beginning and then proceeded to show three completely different things, some just being random tv shows. The whole middle section of the plan had static in their headphones so they were unable to watch the movies. The crew was friendly but seemed very confused as if it was their first time working together. Announcements were choppy And confusing. They also asked me to pay 190 dollars extra to sit with my husband. Not the best experience"

Cons: "Sticking me in the middle row"

Cons: "Bathroom was disgusting. Sink and toilet clogged and filled with paper"

Pros: "Everything was fine."
Cons: "No issues."

Cons: "Connections to US destinations now require your checked in baggage to be processed before you can proceed to your connecting flights. The real problem is that this is no sign or communications describing this. Everyone is simply stopped in the corridor and told that they cannot proceed farther until their name comes up green on a monitor. Unfortunately the monitor switches displays so frequently that it is almost impossible to read. In addition to that it seems names do not always appear on the monitor unless you get your boarding pass scanned a the desk (this is not communicated to you unless you ask why your name is not on the monitor at all). People late for connecting flights (because of inbound flight delays) are required to wait without explanation sometimes needlessly if they don't have a checked bag. A nightmare if you're trying to make your connection. In addition once you've cleared that hurdle you need to go through security again (something we were unprepared for since we were already in the secure area. You then proceed to customs and then your connecting flight (if you haven't already missed it by then). Allow lots of time to get to your connecting flight, and ask to get you boarding pass scanned at that mysterious "checked bag" stop in the corridor."

Cons: "It’s mainly all good but there are never really snacks on air canada other than pretzels (and today not even that). They are still my fave airline but they could step that up a bit!"

Pros: "Friendliness of staff My familly got to follow my flight very closely."
Cons: "Delays and harsh trubulance (altough i know that wasn’t air Canada’s fault for the weather) The changing of gates and the changing of boarding time without being updated on the application. The changing of the gate was changed moments before the boarding"

Pros: "general state and size and comfort of the plane. Overall AC experience always good. The flight back to montreal, the service was exceptional!"
Cons: "only a dairy plate available, next time I need to specify no dairy entertainment -- too many ads and no previews for the movies so I have to start playing then stop and go through the entire same series of ads for the next one. the system just seems clunky and antiquated in today's tech age."

Pros: "Comfortable seats, friendly crew."
Cons: "Almost two hours delay each way."

Pros: "On time, entertainment screen"
Cons: "that there is a charge for headphones"

Cons: "Late flight No communication Had done pre register to sit with father. They changed his seat upon boarding."

Pros: "Very good crue"
Cons: "Very concientiousvAiur Canada employees"

Pros: "I enjoyed the crew, the food and the entertainment. The crew did give us peanuts for our extra 5 hours on the plane."
Cons: "We were 3 hours late for departure and took 2 extra hours in the air because of re-routing. The seats were abnormally stiff and went back so little that it was extremely hard to fall asleep during the 18 hours we were on board. The crew was unwillng to let us bring our instruments on board and thus, they cracked from the air pressure during the flight."

Pros: "Service flight on time food"
Cons: "No movies for 7 hour flight"

Cons: "No entertainment no snacks no checked in luggage. You have to pay to rent iPad to watch inflight movies as pay for earphones. Air Canada has become a premium priced airline with extra low cost /no frills service. Sad and disappointing. Last time I am flying with AC. Rather book cheaper airlines and know what to expect than pay a premium and get even less than the low cost option. Boarding staff was rude pushing people etc"

Cons: "Gate change but no announcement"

Pros: "We flew Toronto to Milan"
Cons: "Air canada doesn't know how to run an airline and should stop trying. They are hurting all of their passengers,and they do not care."

Pros: "Staff was very helpful and kind"

Pros: "We received generous vouchers, when our flight was delayed prior to its cancellation."
Cons: "The only disappointing thing about our flight was the cancellation without warning and explanation. We then had to work to get on a new flight as some of our party were not automatically re-booked."

Pros: "Boarding was good, but pretty bad flights overall. One of the worst I ever had in my life! The plane seats we had had so little cushion that is was painful to sit. My husband was avoiding touching the back by leaning on his arms and he is great shape, don't think elderly and in pain by himself...Entertainment simply non-existent and food as well... The crew were borderline okay. Plus the plane drove for about 20 minutes at Montreal and about 20 in Chicago before we left and after we landed...Let's say I saw parts of O'Hare in Chicago, I didn't even know existed!!!"

Pros: "The flight attendant was very nice and smiling."

Pros: "$800 reimbursement 1st class"
Cons: "They overbooked the flight by 2 passengers."

Cons: "I arrived at the gate and looked at my ticket to see "GTE" where the seat number usually is. I was informed upon arriving at the desk at the gate that that meant Air Canada has also decided to participate in the ridiculous practice of overbooking their flights and that even though I purchased my ticket roughly 8 weeks prior, there was a chance I might miss my flight to my friend's WEDDING. The lady who was working the desk was as unhelpful and dismissive as you could possibly imagine, refusing to look at me and giving me attitude for merely waiting in the area to see if anyone had missed the flight so I could get on. It was surreal; the only way I could describe her incomprehensible behavior would be to say it was as if her boss were right in front of her and she was trying her damnedest to get fired. It was one of those situations where you could tell this miserable, miserable person was enjoying the power trip she was on and doing everything in her power to make me feel helpless and angry. I made my flight, miraculously, but it was the worst customer service experience I have ever had in my life, airport or not."

Pros: "Professional fight attendants, very nice."
Cons: "The flight took off late but most of the lost time was made up during the flight time."

Pros: "Crew quite courteous and helpful. Smooth flight and landing. Pleased overall."

Pros: "Efficient and helpful."

Pros: "Everything was perfect"

Cons: "Air Canada failed to transfer my bag from flight 1 to connecting flight 2. This not only happened to me but to other people traveling on the same connecting flight as well. My bag was delivered later then the promised time, it was also returned damaged. It is now almost one week since I have taken my flight and I am unable to process a claim because they have not updated my file via their Bag Tracer program. It is clear that they still have a lot of work to do to be considered a real commercial air line company"

Cons: "Flight was late so I missed my connection. Then my luggage was delayed by five hours behind me. Generally poor service."

Cons: "Nice flight"

Pros: "Seats were comfortable"
Cons: "35 minute delay in departing. Sat on plane at gate waiting to depart."

Pros: "everything was perfect"

Pros: "Nothing"
Cons: "We had to purchase food ."

Pros: "Fast loading and unloading."
Cons: "Late!"

Pros: "The staff rocked it, despite being in a tough position with grumpy passengers. The desk staff before boarding was less helpful. The seats were comfortable. Entertainment was rated low because it was a short flight it really should have been an N/A because I didn't use it. Not sure how to fairly rate that. No food as far as I could tell."
Cons: "2 hour delay, then sat for another hour or so after being the last to board for fueling and waiting for ground crew."

Pros: "Seats had a decent amount of room."
Cons: "Aircanada'swe boarding system is again and everyone in later zones just blocks everyone else. Due to issues mentioned on the flight above my husband didn't get his luggage. We are still waiting."

Pros: "Legroom of seat, on demand and complimentary entertainment system and stable connection of Wifi."
Cons: "Delay of the flight..."

Pros: "Was arbitrarily assigned a seat with extra legroom. No excessive turbulence; landing was smooth."
Cons: "I was among the last to board and had to place my carry-on under the seat in front because there was no room in the overhead bin. This kept me cramped the entire time despite the "preferred" seating. Soft drink servings were really skimpy."

Pros: "Quick flight, on time."
Cons: "The TV's in the back of the seats didn't turn on for this short flight."

Cons: "It was so late, I almost missed my connecting flight. They were not helpful. They did not communicate well and they refused to take any responsibility."

Pros: "All went smoothly"

Pros: "2 seats together"
Cons: "no wine with dinner awful service felt we were bothering the staff movies on AC app were awful food was awful damaged brand new luggage and said they didn't cover the damage awful awful awful"

Pros: "The crew was nice. That's about it."
Cons: "Flight left late. Customer service at ticketing were nasty and rude. Was charged 25 dollars to check a bag on a international flight. The layover in Toronto was a nightmare!! The whole process of customs, rechecking your bag, and Canadian security was way too long and cumbersome. On top of that my flight to the US ended up leaving 1.5 hrs late and most of the wait time no gate attendant was even there."

Pros: "Tv in all seats, individual air controls, the crew was nice and I offered up my bag to go on the checked bags when asked and it was the first one out on the bagged claim"
Cons: "I'm 5'8 and my legs hardly fit when sitting straight in the seat"

Pros: "AC gave special seats for free when we told our travel agent that we did'nt like to be seated in the back of the plane. V"
Cons: "Food."

Pros: "Very easy checkin, nice aircraft, very clean, friendly staff."

Pros: "I like the comfort of the seats and how fast the boarding and take off was."
Cons: "I did not like that I was not offered peanuts during my flight. The last time they offered free peanuts"

Pros: "was forced to spend the night in Toronto because Air Canada didn't seem to know that there would be a huge crowd at the airport that evening. I was told as I exited my flight that I would not make the connecting flight and I had to spend the night in Toronto. I will never fly Air Canada again"

Pros: "The crew members in both the flights were amazing. they seemed like they enjoyed their job. Its not very common at Air Canada."
Cons: "The flight from Chicago to Toronto was delayed by half hour. But the boarding gate agents did not even mention the delay."

Pros: "There was excellent leg room by modern standards seats were comfortable flight was very fast once we left Montreal. Plane was landed very smoothly"
Cons: "Sat at the terminal for well over an hour waiting for fuel, or so we were told. Food was non-existent, except for purchased food. Not even a peanut. Drink selection lousy crew was variable, as one attendant was less than pleasant. others were fine."

Pros: "My air Canada app. Worked great for entertainment"
Cons: "Sitting on the plane for over an hour before we could take off The plane needs a good cleaning. Small size bits of garbage on the floor next to the wall. It's getting missed ... Needs to be vacuumed"

Pros: "Air Canada service was wonderful for the Mtl-Toronto keg of the journey. Comfortable, efficient and pleasant"
Cons: "the electronic self booking is a bit unclear and stressfull. More staff on hand to assist and help with questions would be good."

Pros: "The flight was easy and quick. These small planes are actually pretty comfortable."
Cons: "Waiting for a gate in Chicago is never fun. Most people on the plane seemed to have tight connections, and I'm guessing most of us missed them. I only made mine because the next flight was delayed."

Pros: "Good communication from crew concerning updates and ETAs."
Cons: "Service was a bit brusque at times, but never unkind."

Pros: "Seats were very roomy and pilot did a great job!. Boarding went great!"
Cons: "We were stuck on tarmac but this was weather related. No gluten free snacks. Some crew was nice others less so."

Cons: "It was a long delay, which meant I missed my connection at O'Hare even though I had a 3 hour window."

Cons: "Delayed delayed delayed"

Cons: "I was put on an Air Canada flight and sat on the tarmac for almost THREE hours in MTL. Finally took off and am stuck in Toronto overnight. Air Canada was very unhelpful. I have to sleep in the airport. No food vouchers. Sucks."

Pros: "Boarding was quick, staff was friendly and helpful."
Cons: "No in flight entertainment..."

Pros: "Bad good, good service but 5 hours delay"
Cons: "The airplane food and the delay in Chicago"

Cons: "My flight was delayed 9 times with 9 different gate changes. I was supposed to arrive by 10PM and didn't land until 2 AM."

Pros: "Nothing"
Cons: "Flight was delayed. Now have to sleep in airport because connecting flight was missed. Terrible experience."

Pros: "Another flight was issued"
Cons: "My original flight schedule was cancelled"

Pros: "Flights was ontime"
Cons: "Plane was too hot, and then way to cold. This seems to be a re-occurring problem. I am not sure why the plane can't just be set to be be 68-72 degrees. There is no need for it to be above 80 or less than 60."

Cons: "Unable to depart due to pilot wanting windows washed. Created significant delay. Had to rebook flight for next day. Additional cost as a result. I will seek a refund which was due to the delay."

Pros: "It ending"
Cons: "I don't even know where to begin. Horrible flight with two obnoxious dunk clowns that kept this red eye flight awake. Because they were loud and obnoxious they got all the service on the flight. The way they acted, very inappropriately to another passenger, and sneaking booze from their carry on-Wished there was an air marshal on the flight. Won't be flying United again."

Pros: "Crew and workers were all pleasant and polite"
Cons: "United knows they can't fly into Orange County after curfew. This was handled terrible. After 4 delays. All weather related we were finally boarded. Yay hope. Not even to our destination. Boarded to LAX. Now we are seated. The announcement pilots won't fly. No. It is illegal for them to fly. Why not tell customers. Don't blame pilots. Also you know the rules why board us. Even if we flew we still needed a two hour ride to SNA. It was sheer luck I called and was told another flight leaving in 8 min at gate 14 ten gates away. My running to catch that flight was not good. I made it panting. Arrived in LAX at 2:00 a m Not my destination. If nothing else people should be compensated by United don't you think?"

Pros: "Flight on time."
Cons: "Seats uncomfortable"

Pros: "The flight to OHare was fine. No problems whatever. There was no entertainment. The juice was ok."
Cons: "The snack I could not eat for dietary restrictions."

Pros: "Good in flight entertainment"
Cons: "seats were a little less shitty but still shitty"

Pros: "Excellent service and friendly staff"
Cons: "Absolutely not enough room to stretch your legs"

Pros: "Lots of turbulence"

Pros: "Crew was great"
Cons: "Very complicated boarding. Unpleasant and arrogant gate attendand, she did not show too much of interest in helping us. My husband and I traveled together, but we were seated separately. She changed our seats, but the seats were still not together just in the same row."

Pros: "The O'Hare bathrooms, which I shaved in? Everything else about the flights and the airports were awful, like of course"

Cons: "Delayed three times"

Pros: "Flight was n time, boarding was fast and efficient."

Pros: "Nice plane for a small one"
Cons: "Bumpy ride."

Pros: "My daughter and I sat in Economy Plus which was great because it was towards the front and plenty of leg room. We both have long legs, so this extra comfort made our flight much better and relaxing."
Cons: "One of the Flight Attendants was crabby and unpleasant. This was the first time I've ever had an unpleasant Flight Attendant on a United Flight. I travel quite a bit for business and always try to fly United. I always carry a large purse which always stays on my lap and her and I went back and forth because she insisted that I put it on the floor under the seat. This really upset me."

Pros: "So glad the flight left on time and we actually arrived early!!"
Cons: "'Snacks' were spicy and they should be aware not everyone likes spicy food"

Pros: "On time, boarded quickly, checked my carry on all the way through Tampa for me"

Pros: "Everything was as described"
Cons: "Small plane"

Cons: "A lady with a dog on a leash was allowed on board. I do not think it was a service dog. In the gate area, the dog was encouraged to get up on the seat. The owner also walked the dog over to a couple to visit, and the couple had a large cat in a carrier. The dog owner did not see the cat in the carrier for a few minutes. Then, when she did realized it she did not move away. You could see that the dog noticed the cat and was getting excited, and proceeded to bark. I don't know why she didn't back away when she noticed the cat. On board, the dog, still on a leash, didn't stay under her feet. The owner did not hang on to the leash."

Pros: "smooth sailing the staff was pretty good"

Pros: "Newer plane,"

Pros: "The crew were professional"
Cons: "The worst thing is that they schedule a CRJ-70 on this flight. This would be tolerable if the obvious alternative was a turboprop, as if Montreal were a small town, like Flin Flon. But it is not; it is a large and important city, and it stinks that the demand is so low that airlines must use small aircraft on these routes. Is it because Canadian taxes are so high on airlines that fares in turn must be high and not stimulate demand? I can't think of any other reason connecting cities this size would be on crappy little aircraft rather than on at least an A320/737 family aircraft. The problem is that there is not enough room in the overhead bins to fit rollaboards, even small ones like mine. So they have to "gate check" the bag, which does not always reappear at the gate at the destination. Less bad than the choice of aircraft was the fact that after we pushed back, they couldn't get an engine started, so they cancelled the flight and reaccommodated us on a later flight."

Pros: "Plane was clean, crew was efficient."
Cons: "Boarding was a nightmare, baggage took 20-30 minutes on the opposite end to be unloaded."

Cons: "Due to the frequent gate change updates from Kayak we ended up at the wrong terminal. Because of this we were late for our flight which they would not let us get boarding passes for so they bumped us to a flight 2 hrs later. After getting through security we realized the original flight was delayed. We asked the airline if we could get back on that flight and we were rudely told no without a good reason. So we sat for what ended up being and hour looking at the plane we "missed" before it took off. No using United again."

Pros: "Flight was uneventful. Went smoothly."
Cons: "Seating wa very cramped. Long legged people were shoving their knees into my husband's back and I was unable to stretch my legs. Also, there was not a free gluten free snack available."

Cons: "Flight attendants slow to bring drinks around"

Pros: "Crew was very cooperative."
Cons: "Seats were not together we were 3 kids and 2 adults all seats were separate. Crew solve the problem anyway."

Cons: "Seats were not very comfortable."

Pros: "Everything went smoothly"
Cons: "Smoothly and on time"

Cons: "Was told I could sit next to my travel partner but when we went to check in at the boarding gate, we did not have seats together...."

Pros: "Efficient boarding. Ticket price a value."
Cons: "Unfriendly crew. Small, cramped seats. Issues with assigned seats. In-flight entertainment is cost only - i.e. no free option."

Pros: ". We got back 30minutes early then schedule!"

Pros: "left on time without fanfare."
Cons: "internet was weak."

Pros: "Great customer service"

Pros: "I slept during both flights. The connections were close by and I had time to grab a bite to eat."
Cons: "I have no complaints whatsoever. The weather cooperated and the flight crew was super good."

Pros: "Very friendly and great service. Gave us drinks twice."

Pros: "They checked my carry on at the gate in Hartford and said it would go through to me final destination and it wasn't in Cincinnati when I arrived. In fact that was yesterday and I still don't have my luggage."

Pros: "Boarding was smooth-they didn't run out of overhead space"
Cons: "Crew member at gate told me there were earbuds free in flight. I told her I forgot mine and would buy some beforehand but she asked someone else who also said all passengers get earbuds. So I boarded and asked inflight and was told no, not even available for purchase."

Pros: "Plane was 3 hours late missed my connection. Was due to poor maintenance of the aircraft. Will not fly United again"
