Pros: "From friendly staff on the ground to check us in, to helpful flight attendants, Delta has once again convinced us it is one of the better airlines . Will fly delta again."

Pros: "No hassle, no drama, very smooth."
Cons: "The blueberries were rather bland."

Pros: "The crew was friendly and attentive, and the flights were punctual. I was assigned a good seat, and I appreciated the meal, as i was going to arrive in Mexico very late. I also enjoyed the entertainment options."
Cons: "I really have no negative comments."

Pros: "Excellent service, God flight"

Pros: "The one good thing about this unexplained ordeal (the flight was delayed for 5 hours, causing me to miss my connection) was that, after a few hours of hearing nothing (no emails or texts from Delta), I finally saw some options for different flights pop up, so I was able to book a new flight without calling India. Also, I got an exit row seat on my new flight to MSP."
Cons: "They moved our gate about six times and never told us why the flight was delayed. Actually, the biggest annoyance was that Delta told us nothing. The only reason I knew about the delay and gate changes was because of Kayak! I know I am signed up to receive texts and emails from them, but I guess they forgot to notify me."

Pros: "The flight was very quick."
Cons: "They didn't serve us water."

Pros: "Movies"
Cons: "Seats are in humane"

Pros: "Entertainment"
Cons: "Staff were a bit rude. The boarding process was slow as everyone rushed up when they announced the first zone to board, and obviously this was not policed. We didn't get our seats until we got to the gate because apparently we bought our tickets too soon to take off, which was three weeks. Also, staff claimed there wasn't enough bin space so asked people to check their bags. We saw people with two big bags get on board at the start, and then staff made everyone at the back of the line check their bags. But there was plenty of bin space before take off. And we were seated in the last row which can't recline."

Pros: "Staff on the plane was courteous although they skipped half of us for snacks & forgot some requests for water"
Cons: "Was not able to check in online. Was not able to select my seat online. I was told I would be able to do both of these things. Spent 30 minutes trying to find a number to someone at Delta to check in & select seat. I was in Australia & all Delta offices were closed because it was Sunday. Although I had an internationally calling plan, no calls to Delta US would go through. finally found someone through a back channel that would help me. We boarded an hour late, and staff would not answer any of our questions about what was going on or how late we would arrive (they sped up the fight so that we landed on time). Flight ran out of drinking WATER after the first service. Half of our section (Economy Plus) was skipped for snacks. An unruly child was allowed to scream for almost the entire flight & was running up & down the aisles. NOTHING was said to the parents by staff members. Was absolutely the worst behaving child with who I've had to fly."

Pros: "El personal abordo muy amable llegamos a tiempo"
Cons: "En el ahereopuerto de guatemala para chekiar las maletas siento q nesesitan mas personal estuve una ora y quince minutos para poder chekiar mi maleta"

Pros: "Smooth flight."
Cons: "I have broad shoulders and there was a larger gentleman on the window seat. Being in the middle seat made for a very very cramped flight the whole way. Lots of skin to skin arm contact for much of the flight. There was no way to avoid it."

Pros: "The crew did a great job of dealing with delays beyond their control and made sure we - and our luggage - made a connecting flight."
Cons: "No complaints."

Pros: "I liked the boarding process."
Cons: "Bigger seats are more helpful."

Cons: "Got stuck for two hours sitting in the plane because the computer systems went down. Worst experience ever with Delta."

Pros: "Nothing I can think"
Cons: "The seats selection"

Cons: "It was late and i missed my next flight"

Pros: "All I need to say."

Pros: "The environment and efficiency."
Cons: "TIMING"

Pros: "It was on time"
Cons: "Too short of a layover in Atlanta"

Pros: "Everything was pretty good like usual, except when we landed we sat on the runway for 45 minutes waiting for a gate as ours was occupied by a plane that was having mechanical issues. Not great."

Cons: "The flight got delayed by 3 hours or more. I missed my flight from LA to FL"

Pros: "Nothing"
Cons: "3.5 hour delay due to lack of co-pilot. No consessions for delay when asked at gate. Lack of leg room. Broken tv, I asked twice to be fix nothing was ever done."

Pros: "Flight departed and arrived on time"
Cons: "Long time standing in line. People are confused by zone boarding. Stood 30 to 40 minutes in line."

Pros: "Friendly staff and crew. On time efficient boarding. Security in SEA-TAC less than 5 min. Different snacks both flights. Prompt service. On time. Power sources at seats worked."
Cons: "Airport gate area in LAX filthy. No seats. Garbage cans overflowing. Bathrooms smelled like New Orleans street on a Sunday morning. Entertainment system broken."

Pros: "The crew was very kind & accomodating. There were plenty of great current TV shows & movies. The seats were pretty comfortable, above average. I loved that they had roasted salted almonds as one of the 5 snack options."
Cons: "I had earbuds but the little girl next to me did not. I loaned her a pair of mine but I expected the flight attendants to offer them but they didn't."

Cons: "Very dated plane. First class seat was worn, crooked, and uncomfortable. No entertainment offered. Almonds or biscuit cookies were the only food options."

Pros: "Entertainment"
Cons: "Flight delayed"

Pros: "It was a smooth ride and overall very enjoyable flight as the entertainment was very enjoyable and a lot to choose from"
Cons: "It was a smooth ride and overall very enjoyable flight as the entertainment was very enjoyable and a lot to choose from"

Cons: "When I was transferred to Delta's website to book, the date was reset to 6 months in the future. It happened to be the same Monday the 26th so that's why I didn't notice. Delta refused to refund my money. This was a terrible experience and I plan not to use Kayak or Delta again!"

Pros: "on board service was nice and promptly"
Cons: "Delta continúes to use an older 757 in this 6-hour flight with cramped seats and seating arrangement in business class. I have taken this flight several times in the last 2 years and written about this issue but now doubt anybody cares about these comments. To make things worse, my seat would not recline!"

Cons: "The flight was over 20 minutes early"

Pros: "I liked the in-flight service and the complimentary snacks and drinks despite the short trip."
Cons: "I did not like that there was not enough room for our 50L Osprey backpacks to be placed under the seats."

Cons: "Sold us a flight with unassigned seats"

Pros: "Individual screens and earbuds for sale."

Pros: "I liked the fact that they have a train to take you from one concourse to another!"
Cons: "Very busy airport! Boarding was delayed and flight was overbooked. I wasn't too happy but it could've been worse."

Pros: "Boarding was easy. Wifi was available and we got some snacks. Paid extra to sit in roomier coach, was worth it."
Cons: "Still pretty cramped, not the crews fault. Would've been better with the seat back screens"

Cons: "Boarding area; boarding agent; boarding staffing; seating (comfort); flt. attendants: That's all... aww"

Cons: "Delay from Seattle to pasco."

Cons: "The quality of customer service and efficiency was lacking at the check in counter. Wrong information was given to many passengers as far as checking in baggage and being sent to several line ques for the agent to tell me in the end that I was told the information incorrectly since the beginning. I therefore was unable to board my flight on time, got switched to a new flight and the new flight was delayed for 3.5 hours."

Pros: "Good service and food"
Cons: "My non-reclining first class seat was a disappointment on this long flight. The flight was full, so there was no re-seating option."

Pros: "Really liked the plan"

Cons: "Delayed"

Pros: "I'm an American ex-pat who travels to and from between the US and Australia. I do whatever I can to fly on Australian rather than American airlines, as they are always much better in every regard. But in this case it wasn't feasible, and I found myself on a Delta flight. I'd say the overall experience was somewhere between okay-good. Nothing major to complain about, but nothing to rave about either. The entertainment options were decent. I appreciated the variety of newly released movies. However, I would have liked a greater selection of TV shows, and the availability of more episodes. I also appreciated the availability of internet access, but I don't understand why it has to be quite *so* pricey. Surely they could make a bit more on greater volume if they dropped the price a bit. I didn't purchase access, but I would have if it were 40-50% cheaper. The comfort of the plane seemed the same as any of the alternatives. Boarding and deplaning were as they should be."
Cons: "The service from the crew though was simply ok. They were just friendly enough not to be rude, but no more than that. Virgin Australia and Qantas consistently have much happier crews, who make you feel like a dignified guest, even in economy. The food was average at best, and they served two meals where the Australian airlines would serve three on the same flight. They also offered less in the way of snacks and drink refills. It seemed like they were cutting corners here, which I don't appreciate on a 15 hour flight. Also, they said they "proudly serve Starbucks coffee". After drinking it, I don't think they should be proud of that! Again, overall it was a decent experience. Nothing flashy, but nothing too bad either. If the costs are comparable for your flight, you should certainly choose one of the Australian carriers. You'll get better service from the crew and better food. The one caveat, however, is that Delta has WiFi, whereas at the date of writing this, the Australian carriers do not. While access is exorbitant, if you really need to get some work done on the plane, you might choose Delta for this reason alone."

Pros: "We got to board first"
Cons: "The seats were uncomfortable, the food was uneddible and we had to wait a very long time for our baggage"

Cons: "Flight was delayed substantially. Sat on the plan 40 minutes before taking off after already being 30 minutes delayed."

Pros: "Reassuring that the airport desk staff were keeping an eye on my connection from LAX to Columbus. Turned out it was too tight of a squeeze and I missed the connecting airplane's door closing by a few minutes, despite having RUN through LAX to get there."
Cons: "I am disappointed by the lack of communication among Delta staff when we arrived at LAX. Our turn-around was late coming into SMF, thus late leaving. It would have been very helpful if the gate staff at LAX had advised me to not bother to try to make my connection, or called the next gate to tell them we were running over there. RUNNING. Or at least done something to act like they cared. I am disappointed by the lack of initiative. I understand flights cannot wait, and I would have greatly appreciated being saved the trouble of running to a different terminal and instead taking that time to change my travel plans. They may see travelers struggling like this daily, but to each traveler, a hiccup in travel plans trip is stressful and urgent. I ask Delta staff to please consider that when they come to work. Thank you."

Cons: "Took 8 hours to get from Oakland to Los Angeles. Flight delayed then cancelled at Oakland. Driven from there to San Francisco. That flight delayed by 45 minutes. Got on board and then they neede 4 people to get off the plane since it was overweight. That took another hour. Bad day of travel."

Pros: "Food was good, I had the fruit & cheese plate. Very good. I had a wheelchair so she took me directly to the doorway of the plane. Very nice young lady from West Africa. Nice selection of recent movie releases."
Cons: "My seat would not recline. Uncomfortable for such a long flight."

Cons: "1. Boarding order is not by seating making boarding very inefficient"

Pros: "Good crew."
Cons: "My tv screen was not working. I did not have anything to watch my entire 6 hours flight from Toronto to San Jose California. My connecting flight/airline was changed on the day of my flight. Not really a problem as the time was the same."

Cons: "Flight was delayed"

Pros: "The ease of boarding with very nice staff!"

Pros: "Crew did a good job, even with the long delays."
Cons: "Plane was almost 2 hours late getting to LA. Started with the crew needing to clear customs in Vancouver. Delayed by 30 minutes....then the crew preboarded a sick lady and her travel companion. At some point crew decided she should not fly to LA, but the ladies wouldn’t get off plane! 45 minutes later and 4 RCMP show up to escort them off plane. Then we didn’t have any ground crew to get us off loading ramp. Finally got away 90 minutes or more after scheduled departure. Circled LA a few times before getting to land.... long flight with long delays!"

Pros: "Nothing nobody"
Cons: "Uncomfortable seats! No access to music movies or kindle though it said it has free entertainment. Nobody knew how to get access to the movies. Instructions are wrong and loop around with no results. Attendant said she’d comp a drink but didn’t . Boarded late and disorderly. Mean gate lady. Left an hour late. Home an hour late."

Pros: "Very entertaining flight crew. One attendant cracked jokes sang happy birthday announced wedding party . Never boring very friendly"

Cons: "Check in process was brutal. Two different pieces of advice from two different agents. Boarding from front to back of plane is inefficient. Creates clogged aisles."

Pros: "On time Flight. Nice and friendly staff. Assistant at the check in Kiosk."
Cons: "Inattentive baggage security and check personnel."

Pros: "Good amount of leg room. The children were well behaved."

Pros: "The female flight attendant and the pilot spoke reassuringly and with friendliness."
Cons: "This was the most negative experience I’ve ever had flying Westjet. The female flight attendant was wonderful, fun and friendly and professional. The two younger male attendants were incredibly rude, rolled their eyes, ignored me, put themselves first (at one point instead of making room for me to return to my seat the blond one insisted I let him pass when it was unsafe for me to do so and nowhere for me to go). I felt demoralized by these two men and it’s both surprised and disappointed me as Westjet staff have a reputation for friendliness. These two men will Discourage me from flying Westjet when travelling to LA again. Not pleasant. Again the women was lovely. I tried to catch the male names but they wouldn’t stop and face me for long enough for me to see their name tags. They seemed to have some inside jokes between them and gave me the sense my requests were not welcome or respected. I am a nervous flyer and this was such a difficult and uncomfortable Experience."

Pros: "Nice service and efficient boarding since the plan shed Of us at the terminal was delayed for weather reasons. Tasty food, the wrap was great."
Cons: "For a newer plane, it seemed like tighter seat space. Surprisingly harder to get comfortable compared to other plans and it seemed like the seats Space even betwee me and another passenger was tighter than the many other times I flew."

Cons: "How is it that in a 5 hours flight you don’t be get any food for free? You have to pay for every meal. And the entertainment system isn’t only available through the west je to app but i didn’t know that until I board the plane wtf"

Pros: "Trash flight . Took to long to let me off"
Cons: "Rude people"

Cons: "Flight was delayed 4-5 hours then got cancelled then got rebooked for the next flight in 4 hours."

Pros: "The cabin crew especially the gentleman was great and friendly and accomodative"
Cons: "Babies crying lol"

Cons: "Crew was not the nicest, especially when asking for non purchase items like water."

Pros: "Everything"
Cons: "Nothing"

Pros: "Excellent from phone courtesy to every aspect of travelling with them."
Cons: "Well organized. Courteous at every step. Other airlines should emulate them in every way. Travelled all over the world and would rate them as best so far."

Pros: "The ticket price was great. The crew were nice."
Cons: "There is no monitor in front of you/in-plane, so bring your own tablet"

Cons: "Flight was delayed. Staff were rude, slow and uninterested to help. Boarding was very slow, overhead was full. Baggage pickup was excessively slow. Overall a very poor experience with WestJet"

Pros: "Very disciplined and hard-working crew did their best to keep everything under control and moving on schedule. Boarding was busy but fairly well organized considering."
Cons: "Flight had an abundance of minors and babies at no fault of anyone, just unfortunate. Lots of crying, screaming, fidgeting and puking. Customers were pretty impatient in the early morning as well which didn't help the situation. Not sure if snacks or refreshments (other than water) we're handed out in a 4.5 hour flight as well."

Cons: "delayed 2 hours and I missed my connecting flight"

Pros: "Crew was pleasant"
Cons: "Both flights were a half hour late in taking off, and arrival."

Cons: "I dislike that westjet tried to get me to pay for my seats when I initially bought the ticket, only to discover later that the seats are free if I choose them at check in. I didn’t pay the seat charge but there is a breach of trust in them trying to con me that makes me not want to fly with them again."

Pros: "The stewardesses were very pleasant and helpful..."

Cons: "Generally announcemect is too fast and not clear, especially the boarding anouncement regarding the order of boarding is not clear. Please be more considerate for the aged and hard of hearing, infrequent traveller."

Pros: "Flight was good but we were delayed about 2 hours. Not good."

Cons: "Transferring between distant terminals in LAX was a pain. I'm glad that I had a long layover between flights to make the journey that required leaving and re-entering security."

Cons: "I had to pay for internet to download the app to watch movies"

Pros: "On time departures and arrival."
Cons: "Internet didn’t really work."

Pros: "Flight was delayed an hour"

Pros: "Lots of room- great aircraft"

Pros: "Good service easy boarding luggage came out as soon as we were off the plane when you are on vacation last thing you need is to wait for your bags great job all around"

Pros: "Pleasant staff, ample room, ability to charge devices. On time"

Pros: "The overall experience on my westjet trip was great. Everything west jet does - and all the groups in the airport are fantastic !"

Cons: "We left late and had a very hard landing"

Pros: "The people were all very helpful."
Cons: "The system was down. Had to stand in line for an hour. I had carry on and Global entry. But couldn't get my boarding pass without seeing an agent."

Pros: "friendly and relaxed crew, clean plane, on time"
Cons: "No entertainment center on plane"

Pros: "The Crew was excelent, WestJet has the best crew, very courteous and helpful unlike disgruntal AA crew. They also have the best price deals available. I highly recommend this airlines. Thanks"
Cons: "No entertainment unless you buy one of their tablets. Unerstandable given the type of fleets they use."

Cons: "No TV screens, but there was an alternate"

Pros: "I upgraded and that was definitely worth it."
Cons: "I don't like 2.5 hour flights in general. Just long enough to be annoying. But that has nothing to do with you and your airline."

Pros: "It was a relatively short flight, 2 hours."
Cons: "Noisy from group of kids and young women and a sick passenger sitting next to us."

Pros: "Before taking this flight, I was very nervous because of all the bad reviews on here and other sites. The only good reviews seemed to be by people from Alberta (not really trustworthy, as they seem to support anything that's from Alberta, and note that Westjet is based in Alberta...). But I was blown away by how organized Westjet was and how nice they were. All the flights were on time (I had a few layovers), the staff was helpful....I really have no complaints. Sure, they don't have a plethora of great in-flight entertainment such as movies, etc. But when I fly, I'd rather pay less, have the staff be nice/organized, and just bring a darn book to entertain me. It was a great first flight with this company. I would fly with them again....and I can't remember the last time I said that about any other airline. So do yourself a favor: Don't listen to the bad reviews on here (unless you're obsessed with in-flight entertainment and big-butt first class seats)."
Cons: "The movie and T.V. show selection was bad. But that's not a big deal for me...."

Pros: "Crew was great!"
Cons: "Small seats. Nonexistent food and entertainment option are all self provided"

Cons: "I didn't like that you had to download an app for vieweing movies burning flight."

Pros: "Bell's live TV is probably the best feature!"

Pros: "My daughter ordered the tickets for us but she didn't pick seats. We forget to pre checked in, either. Our flight was very full so We are so lucky got the first class seats! This is the first time in our life with first class experiences! It was on the July 4th and saw a lots of fireworks in the airplane! We are so exciting! Thank you for West Jet Airline!"

Pros: "Nothing."
Cons: "1+ hour before we took off after getting on the plane. 1+ hour before we got off the plane after landing."

Pros: "online checkin, fast boarding (a total of only 27 passengers undoubtedly made boarding much quicker), had extra space due to the sparse flight; smooth flight, good refreshments, pilot did a good job of keeping us updated on runway/gate status"
Cons: "on board crew didn't seem interested; empty cup was never picked up; upon leaving the aircraft (after a 30 minute delay due to a problem at our gate) none of the crew said as much as goodbye or thanks. I know it was a late flight with very few passengers, many of whom may have slept, but as such I thought the crew should have been more attentive and friendly at departure. A disappointing experience."

Pros: "Great service! Crew was very friendly and happy. Flight was online and landed early"

Pros: "There was enough leg room and boarding was done reasonably quickly."
Cons: "The flight was delayed by 15 minutes without explanation."

Cons: "The flight itself was great but it was very late in starting due to technical problems with the aircraft."

Pros: "Very good service"
Cons: "Rough air"

Pros: "Staff were pleasant"

Pros: "Love the pods."
Cons: "Food not quite as good as the trip out. Steak was over done."

Pros: "The crew was very nice and friendly. They were very accommodating and genuine."
Cons: "The washrooms should be cleaned during the flight."

Pros: "Generous leg room in coach class"
Cons: "Sat on the runway for almost an hour both to and from my destination"

Cons: "Took 2 standbys and much time in “service” lines to get another flight. Added six and a half hours to my day"

Pros: "Short flight, crew."
Cons: "Delays and boarding."

Pros: "I liked the service on the flight. I was lucky to get two seats free. It was a comfortable ride."
Cons: "This is the third trip with Air Canada and their time it was delayed. The entertainment app is very poor and annoying to use."

Pros: "The food and the crew"
Cons: "Nothing"

Pros: "No in flight entertainment system. I hate those things. They take up room and lots of times you can't even turn off the screens. Streaming to personal devices is a much better solution."
Cons: "Food for economy class 10 hour flight was: Dinner: a bowel of rice with a couple of shavings of meat, bread, and a brownie. Snack: pretlzes Breakfast: small loaf of bread with a tiny amount of meat filling. Absolutely eat before boarding this flight. All you will get are carbs. The foam on the seats was thin and not comfortable. This airline can be a bit cheaper than others but I don't think it's worth it."

Pros: "Nothing positive to say"
Cons: "Originating flight was delayed, so missed connection in Montreal and had to be rerouted. After going through 5 airports to reach our final destination, we finally made it - without our luggage!!! To make matters worse, the complete and extreme lack of empathy on behalf of Air Canada's customer service desk was less than appreciated by us.... As it turns out, Air Canada was aware all along that we would miss our connection; however, they still had us board our originating flight. The gate agent should have been conscientious and informed us that the delay was ongoing with our flight being number 22+ on the tarmac to take off, thus guaranteeing our missed connection. They should have rebooked us on another flight from our original destination vs rebooking us upon arrival in Montreal to miss further connecting flights. Very disappointed!!!!! Based on this experience alone, never again will I or my family travel Air Canada."

Pros: "Chris from AirCanada customer service is a true hero to the industry and I'm sure he deserves much more recognition than he gets. Thanks Chris for helping save our travels!!!"
Cons: "When checking in for our flight, AirCanada prompted me to select which passengers' email addresses should be used to send updates in case of changes, delays, or cancelations. I selected the both of us to receive the updates. However, we never got any notice that our flight was CANCELLED. They cancelled it well in advance that had we known, we wouldn't have gone to the airport but NO - we already arrived and passed through security only to arrive out by the gates and see on the board it was cancelled. Even while passing through customs, the officer said he didn't see it on the flight schedule and then said, "oh it's just listed at a different gate." The way in which AirCanada handled the incident was completely unprofessional and just plain stupid. I for sure will be giving my business to Amtrak or Greyhound the next time I need a trip from NYC to Montreal."

Pros: "I love the excellent friendly service!"

Pros: "We paid to upgrade our economy seats, so there was leg room and the seats were roomy (we were immediately behind the first class area). Service is pretty good. Not great, but pretty good."
Cons: "The food was terrible! We know airline food is usually not great, but come on folks! I will cook spinach pie for all and bring it next time! The lunch was ok, but the snack (bad chocolate cookies) and the dinner (hot pocket type thing) were really bad and terribly unhealthy. I skipped lunch because I bought it from the airport because on the the way in I tried the meals and knew it would be bad...Entertainment was even worse! I did the AC rouge site with my iPad. The movie I chose was interrupted every 4 minutes for commercials-the SAME five commercials mind you-AND every time they stopped, the movie would start from the beginning! Ridiculous really...."

Pros: "It was smooth and great trip."

Pros: "The airplane was clean."
Cons: "The airline is so cheap they didn't even offer us a bag of pretzels during a five-hour flight."

Pros: "In flight movies were clutch"

Pros: "Flight crew were great and their service was impeccable"
Cons: "Airplane was changed and what was supposed to be an emergency row seat with leg room, became a regular seat. Also, the boarding process was longer than necessary as zones 3-5 were squished into one line."

Pros: "Excellent and diverse film selection. I broadened my horizons watching documentaries on hacking, gun running, and on an Afghan refugee teen in Iran, a film about a black American teen in Germany, and a French drama."
Cons: "Most of the time economy class is uncomfortable because of the lack of foot room. So this time, for the long flight from China, I chose an exit row precisely for the extra leg space. However, there is no footrest at all , which as you're surely aware, is terribly uncomfortable when sitting for long periods, let along trying to sleep. Furthermore, the exit row seats are not provided a substitute for missing the usual back-of-the-seat pocket with magazines ; that means no spot to place books/papers/trash for the entire flight. Finally, I am 5'2 and petite, and was seated between two fairly slim men, and yet we were still all squeezed side to side. I had no elbow rest. I actually rested my head on one man's shoulder, once he was asleep, and hope he didn't notice. While this is unfortunately typical of economy class, it is not decent."

Pros: "Roomy, professional, friendly. Very efficient. Beverages, meals and snacks were timed well, so that the long flight felt like it went much quicker. I'm not particularly picky or spoiled, so me rating the breakfast and lunch as great, may not be the same fOr others. But my meals were delicious to me. I would definitely fly Canada air again."
Cons: "No complaints."

Pros: "The blankets and pillow provided to every single customer. The food was actually pretty good except for the breakfast meal could have been a little better."
Cons: "Pretty much just the breakfast meal and the buttons on the armrest, the person to our right kept accidentally turning on my light and changing my volume with her elbow."

Cons: "AC was helpful arranging a delivery of the delayed luggage. But carrier was further delayed from the scheduled delivery time."

Pros: "Besides a french men close to us that doesnt know what is a deodorent , everything was fine for the travel : ontime, friendly staff, no problem at all. Always recommend air canada for its quality standard. Complimentary drinks ok"
Cons: "Pay-to-eat only, no little crackers like before , come on!"

Pros: "The flight attendants tried their hardest to keep issue minimal."
Cons: "The second engine needed for take off had issues so the airline tried to get second engine replaced. Unfortunately the second engine also controlled the air conditioning. We waited through 3 engine replacement tries in the hot Italian summer inside a hot cabin with approximately 150 passengers. Almost an hour later, engine was replaced but damage was done. Many transfer flights had to be rescheduled for later flights. Where was the reimbursement???? Just a million thanks for our patience. Time is money"

Cons: "it was delayed for 1 hour"

Pros: "We got in a little early. More room than many in regular economy. All employees encountered pleasant and competent."
Cons: "Nothing comes to mind other than the normal air travel has led of security."

Pros: "comfortable seats and friendly staff"
Cons: "no problems with this flight"

Pros: "Safe and on time. I liked the opportunity to check in my carry on luggage."
Cons: "TV's did not work and the flight attendant bumped into me every time she walked down the aisle. Earphone plugs did not function properly. Outlet to charge my phone was missing."

Pros: "Not much"
Cons: "Food is awful and the seats are the most uncomfortable I have ever encountered!"

Pros: "the flight attendant was nice at least on this flight"
Cons: "the flight was delayed for an hour in a terminal where 4 other flights were scheduled to take off at the same time. the flight was delayed for an hour, and then I sat in the plane for another hour. The staff in the airport were super rude and didn't seem like they cared at all. There was nothing express about this flight."

Cons: "My original flight was cancelled due to mechanical problems and then agent got me in a other flight to Newark which was the last one to NY and then there was a delay of at least 1hr to take off. Most likely, I will not travel with air canada again and I'm not recommending to friends since they are always delay with their flights."

Pros: "I liked the entertainment best I guess, it's very difficult to be comfortable in those horrible long flights. The crew was nice"
Cons: "So cramped, I know you want the highest profit margin possible but I don't appreciate spending 1800$ to feel like a prisoner. The food was barely food."

Pros: "Pros: The onboard crew was nice. The entertainment was good (nice selection of television and movies) There is an entertainment touch screen for each individual."
Cons: "Cons: They moved the gate THREE times! We had to walk all over the airport because they were so unorganized. The seats were VERY uncomfortable. It was difficult to sit for even a few hours. There are no snacks unless you pay. The entertainment touch screen is of poor quality."

Pros: "Everything went as planned, no delays, left on time, etc.. As good as it gets! and my flight was amazingly cheap! very happy flyer."

Cons: "Toronto staff was not helpful in aiding us at the gate. We had to wait u tip anther staff member showed up. We boarded and then sat on the plane for 30 minutes while waiting for crew to bring luggage. The entire Toronto experience of customs was unpleasant and chaotic. We will try to avoid flying through Toronto again on an international flight."

Cons: "The person checking me in to getting seat assignment must have been having a bad day. She was downright rude."

Pros: "From the views read I cannot say I had the same experience. Crew was helpful & kind. Flight was on time and comfortable."

Pros: "Nothing really."
Cons: "The fact that 10 minutes before we were suppose to originally board the staff at DTW was trying to get people to give up seats because they oversold the flight which should have taken care of before that. It also doesn't help that the flight was late arriving and unboarding so that it could be reboard by new customers and updates were unhelpful and useless when attached to the plea for someone to give up their seats. 0 out of 5 stars...would NOT recommend."

Pros: "The flight attendant was well informed and quite helpful."

Pros: "Plane late, flight three hours waiting to leave"
Cons: "Had to wait."

Cons: "The flight from Munich to Toronto did not exist !!!!!! There was no air canada flight on 2/2/2016 Thank you star alliance for rebooking me ! Horrible customer service, no e mail sent, ever."

Pros: "Nice new aircraft. The entertainment system functioned really well (not tapping multiple times on the touch screen!). Although the quality of the meals was nothing to write home about, at least we got two meals and a mid-flight snack (United has done away with the mid-flight snack)."
Cons: "The headrest on the seat does not bend to cradle your head. Minor details but it subtracts from the comfort."

Pros: "Really flight was very good, but seats to family member given separate seperate."

Pros: "the short flight"
Cons: "the comfort and location of seats ran around for days acquiring a doctors note for easy access seating. grateful for the refund but would've rather paid and actually been accommodated."

Pros: "Nothing"
Cons: "Plane was delayed 5+ hours due to maintenance problem. We had to sit on the plane for ½ hour before they finally let us deplane. Finally they putt us on a different plane. We were packed in like sardines. No room at all. Full disclosure, they did apologize profusely and gave us all $50 travel vouchers for the inconvenience."

Pros: "Great flight good service friendly staff great price"

Pros: "United airlines staff were polite and worked hard."
Cons: "I did not like that they printed my ticket for my connecting flight for EVA Air without any EVA Air markings. This meant that when I arrive at LAX I was giving directions to the United Airlines terminal when I really needed to be at the terminal for Eva Airlines. This caused me to almost missed my flight with Eva Airlines. For the remainder of my trip EVA airline staff were quite grumpy with me for being 45 minutes late boarding. I actually am thankful that I believe they held the plane that 45 minutes for me. It just seems too convenient that the plans out there that long after its scheduled takeoff."

Pros: "Friendly, attentive staff. Great seats with plenty of leg room."
Cons: "Nothing"

Cons: "There is a reason why I stopped flying and this airline and now I remember why. I was not assigned a seat on the flight and checked int for a seat assignment at the gate. When I asked the boarding rep at the gate for an aisle seat, she lied and said there were none left but when I looked online, there were more than 25 available. This flight was awful, uncomfortable, the plane smelled like a geriatric center and was dirty."

Cons: "Service"

Pros: "The easiness of the airline to adapt to the fact that we will be going late and the swiftness in organize all the passengers in a way that no one will miss their connection flight"
Cons: "I had a child with me and I was sat in the row before the emergency exit, where the seats were rigid and my child was not able to sleep at all. Making it uncomftable to all around her."

Cons: "There should be some free tv"

Pros: "The way they said "Hello" to me. Other than that, the water was good."
Cons: "Everything else. My flight was delayed for weather, and I missed my boarding by 2 MINUTES, and they rejected me at the gate, and told me my seat was already taken by stand-by. Then the lady I went to see at the customer service desk was rude, and rejected me from first class even though it was THEIR MISTAKE I was booked there. Then I didn't even land at LAX! I had to take another flight that landed at Ontario so I can make my appointment on time. Will NEVER travel with United again!"
