Cons: "Flight was delayed, crew in general was disorganized, most usb charging ports weren’t working, touchscreen is very outdated"
Pros: "The on-board crew were great. Super friendly and chatty. Almost a WestJet feel instead of the serious aloofness that AC is known for"
Cons: "The entire HUGE MESS from booking til sitting on our last airplane. The “new reservation” system is a horrible joke. The right hand doesn’t know what the left is doing so you get completely wrong info and they won’t do anything about it. I’m a wheelchair assist and had to call 6 times to remind them to put it on my ticket even though each time I was shown that it had been added. They kept seating on the back row of the plain and blamed me for not calling ahead to “let them know I was wheelchair assist so they could reseat me” BUT...they won’t answer you call unless it’s 24 before your flight and then to check at the airport who then tells us it’s out fault cause we didn’t call more then 36 hrs ahead...YOU CANT CALL THAT FAR AHEAD...and ...get this “they don’t have wheelchair assist on my ticket/file”. I about lost my mind over the hours on hold and every different answer as to what what to do and in the end blamed us. ASTONISHING TO ME. THEN THEY HAVE THE NERVE ON-BOARD TO ANNOUNCE THEY ARE THE BEST AIRLINE IN NORTH AMERICA 2019...HORSE PUCKY!!!"
Pros: "Great flight crew and smooth landing"
Cons: "Pretzels are not a good snack"
Pros: "The crew was nice."
Cons: "Everything is too cramped. The sound on the entertainment unit is terrible."
Pros: "Nothing good to say for this flights overall."
Cons: "Spent over two hours on the plane/tarmac waiting for take off. Air Canada sucks."
Cons: "Extra rules about headphones are annoying and no beverage options. Horrible terminal that does not let you get a drink before boarding and gate agent did not update boarding when it was late, so no one could venture off and get a drink of water before flight."
Pros: "We didn’t crash."
Cons: "We continue not to crash."
Pros: "I sat in a seat that wasn’t my assigned seat, and no one said anything. It was awesome!"
Pros: "On time, smooth flight, good movie choices"
Cons: "Cramped seating"
Pros: "The few were friendly."
Cons: "The food selection was poor."
Pros: "Service counter staff was helpful to confirm seating although I did not like being put on standby. This happens too often with Air Canada."
Cons: "Stop the overbooking!!!!!"
Pros: "Entertainment options"
Cons: "My wife’s screen did not work. The pitch between the seats was too narrow for a transatlantic flight. Older plane that needed to be cleaned and updated."
Pros: "nothing"
Cons: "See above - seats worn out, entertainment worn out, Crew battling old tired aircraft. Massively overpriced. Bring on WestJet direct to Ottawa."
Pros: "The seat beside me was vacant, so I had extra room."
Cons: "Flights in the late evening from Toronto to Ottawa always seem to be delayed. We spent a lot of time boarding, and a lot of time de-icing before take off. There would have been plenty of time to serve refreshments during de-icing. But refreshments and dismemberment of ear phones only began once the plane was airborne. There was not enough time to service all the passengers at that point. I'm not sure why Air Canada cannot at least give you ear phones when boarding. And why cannot refreshments be served during de-icing?"
Pros: "Air Canada is fantastic. Will never use air india."
Cons: "I liked everything about AirCanada and nothing about Airindia."
Pros: "First flight comfortable fast clean aircraft Second flight older plane small not as clean"
Cons: "Air canada has a problem at every arrival gate each time we landed there was no sttebdebt st the gate and so we sat on the tarmac fir a while while they awIted somebody to come and drive the Jetway to allow us to park and deplane This happened all three times"
Pros: "the cew was nice"
Cons: "The terminal had no food options at all when we were in a very delayed flight and hungry. We were not given seats ahead of time and therefore were assigned the last row which was very uncomfortable and could not recline. No one was at the desk to help with the seats for a Very long time. The boarding process was not good."
Pros: "Arrived on time"
Pros: "Didn't actually take this flight due to a missed connection."
Pros: "The staff were very friendly."
Cons: "Some of the equipment on the airplane didn't work. TV monitors."
Pros: "Wasn't too late. Plane seemed clean."
Cons: "Seated beside a young child with behavioral problems. Father mostly slept. Child stood on seat and jumped up and down, crawled under seats, threw ipad on my foot repeatedly, spilled his drink all over himself and his seat, screamed whenever his seat belt had to go on or his table top couldn't be down. At one point, the dad lost his temper, swore at the child, and covered him with a blanket in a big screaming match before doing up his seat belt--I was afraid he had smothered him but it had the effect of calming him down. No attendant even tried to intervene apart from asking "can I see your kid's boarding pass?" People should have to disclose when they are travelling with a child with severe behavioural problems and attendants should rescue anyone forced to sit beside one or at least make the parent care for the child. Also, a minimum of crackers or pretzels would be nice with drink on 5-hour flight. The entertainment system wasn't operating correctly and kept having to be reset by crew or reset itself. And, after first class etc. board, why don't they board the people at the back of the plane first, not the ones at the front? It took forever because people in front zones hadn't settled into their seats before people from the back zones tried to board."
Pros: "I'll like it when i board."
Cons: "The fact i haven't boarded yet."
Pros: "Air Canada you suck. Told us that our flight wouldn't leave before we boarded as the computer system was down country wide. We still stood in like for an hour and hey could have manually checked us in as they did others. We were promised no planes would leave and when we got to the gate our plane was pulling away leaving 10 of us to scramble to find another flight. Customer service argued with me saying no flights were going to Ottawa and my Kayak app told me otherwise. Thanks for making my flight home for a funeral that much more stressful and having my family wait 4 hours risking all of our lives with freezing rain drive home."
Pros: "Entertainment"
Cons: "too hot in cabin missing brewage onboard"
Cons: "The crew didn't finish the inflight service so a bunch of us didn't get drinks or snacks. This was all the more frustrating when the flight then circled Ottawa for 20 minutes before landing."
Pros: "I think cost me without needing to go back and forth"
Pros: "Pathetic delay time that was not weather related, they should have had another plane. I will not say that I will never fly Air Canada again just because departure time may leave me no choice but given a choice that suits my travel schedule it will not be them."
Pros: "same as above"
Cons: "same as above"
Pros: "good overall...so MUCH BETTER THAN Air Canada rouge service we took from Ottawa to Venice. Rouge service is very poor!!"
Pros: "The pilot and the crew are very proffesional."
Pros: "Everything on time"
Cons: "Nothing"
Pros: "Cleanliness, crew (in general)."
Cons: "Problems with entertainment system sound seem to be a recurring problem aboard aircrafts - the jacks seem to be in bad shape in most, whether for the provided eraphones or those brought on board."
Pros: "Air Canada is not a goo Air Lines for customer service."
Cons: "I do not like there customer service policy."
Pros: "Airbus 380"
Pros: "Same as anove"
Cons: "Nothing"
Pros: "Service was poor. Attitude was less than enthusiastic."
Cons: "In order to make more money, Air Canada purposefully sits couples, families etc. who book together separately, in order to try to get them to buy upgraded seats together."
Pros: "Leg room adequite."
Cons: "Only beverages served, there wasn't the usual snack."
Pros: "Seat availability (lots of empty seats) Entertainment system had lots of movies & music Friendly flight attendants"
Cons: "Flight attendants could be more aware of his/her surroundings. For example, I was either stepped on (as a result, being woken up) or my backpack was stepped on several times when an attendant was walking down the aisle, and neither of those things were sticking out into the aisle. This has rarely happened to me on trans-Pacific flights (more crowded, longer flights) so I can only attribute it to the carelessness of the attendants and/or the aisle width but since I think aisle width follows international standards it's more likely the former."
Pros: "It was great"
Cons: "My "window" seat was beside a wall. So i actually didn't even have a wi dow seat, not really."
Pros: "They were able to put me on standby for the next flight and I made it on. I would have been upset if had to wait for the last flight at 10:55pm. I understand this is not always in the airports control."
Cons: "My flight from Montreal to Ottawa was canceled and I almost had a panic attack. I was flying alone for the first time."
Cons: "No good movies or music"
Pros: "I arrived early and was able to change my flight to an earlier one."
Cons: "The air hostess/stewardess was surly...and looked like she hadn't slept.."
Pros: "We left and arrived early, the seat was surprisingly comfortable (it helped that there were lots of empty seats, including next to me), my full-size carry-on fit easily in the overhead bin, despite it being a small plane, the in-flight entertainment was always on and pretty good... everything went well."
Cons: "Only the things I've grown to expect on any domestic service (e.g., no food)."
Pros: "The fact that I was rebooked immediately to my new flight AC-DC 705 at 8:50 am by two wonderful ladies at La guardia airport who comforted then boarded me unto a flight due to the fact that I missed my original flight. This occured due to the Airport being Unorganized! As I had checked in well before 3 hours and was on time for my original flight at 8:30 am."
Cons: "The airport was extremely packed, Unorganized and not well staffed. What I hated is that when I arrived at my original gate A7 the gentleman who boarded my original flight was unprofessional, rude, basically ignored me and said "You missed your flight !" Not even taking the time to listen to my situation or guide me in my next steps of acquiring a new flight to go to my classes and home in Toronto!"
Pros: "Everything but the size of the in-flight seats"
Cons: "Seats way too small and uncomfortable."
Pros: "AC changed to a different plane for our flight at the last minute, so seat assignments were messed up, and we had paid extra to choose seats. So why pay extra for seating when the airline can put you wherever they want at their discretion. In addition there was a minor delay in take off while the flight deck crew had to re-programmed the avionics to our scheduled route. But we made up the time en route and were only a few minutes late. On the whole, not a bad flight experience, just the usual frustration in the process. I long for the days when flying was a pure pleasure."
Pros: "Flight attendant very caring and friendly."
Cons: "Gate attendant very rude - made my daughter cry Her seat was way at the back. Baggage handlers lost a luggage strap - sturdy one 7 boarding pass The gate was changed to one at the end farthest from original gate It was supposed to be two flights - she ended up with 7 boarding passes in the end. Second really unpleasant flight with Air Canada in less than a year. Will avoid Air Canada from here on."
Cons: "Salty pretzels!"
Pros: "flight was on time"
Cons: "not even a little snack served with the drinks and the amount of legroom was minimal and I'm not tall"
Pros: "Good crew"
Cons: "No wifi"
Cons: "The WiFi did not work the entire flight (4 hours from Chicago to Seattle) and despite passengers inquiring multiple times, we were never informed whether to expect it to start working or not. Streaming TV was also poor quality on the United app."
Pros: "The crew was friendly and helpful."
Cons: "I have no complaints!"
Cons: "Drop-off bagage agent made me line up to get a new baggage tag even though my luggage had been checked up to my destination via COPA Airlines. A United Airlines check-in agent told me that the baggage agents don’t work for the airline therefore didn’t know what to do. These people need add training."
Pros: "Crew amazing, smooth flight and on-time"
Cons: "Legroom and the fact that there is even s lower version of economy now! Yikes"
Cons: "Serious turbulence. I don’t know to what extent it was avoidable, but my family was terrified for several minutes and nervous for the remainder of the flight."
Pros: "On time departure & arrival"
Pros: "Pleasant flight crew and comfy seats, even in coach."

Pros: "They did allow myself and children to board earlier 5/4."
Pros: "Crew was friendly, smooth flight."
Cons: "Seats are terrible."
Pros: "Getting off the plane"
Cons: "Crew disappeared for most of the flight as if it were a red eye and only served everyone one package of pretzels and came by with the drink cart once...this was on a seven hour flight. they did come by two other times wth a Tray of water but overall were not very friendly whatsoever."
Pros: "It was fast"
Cons: "Nothing to complain about"
Pros: "Legitimately, nothing was liked."
Cons: "My plane broke, worked multiple mechanicals, returned to the gate, my severely delayed departure caused all my connections to be missed thus creating more compounded issues. HUGE HUGE headache. Almost forgot, I'm still missing my luggage 2 whole days later."
Cons: "Excellent"
Pros: "The space on the plane, we left on timeand arrived early and I was able to sit by myself."
Cons: "One of the stewardesses spoke very harshly to me. I felt very embarrassed and offended."
Pros: "At least UA rebooked me next day no charge."
Cons: "Had to cancel trip until next day due to initial flight so delayed I would have missed connection in Denver. Since UA claimed was weather related, I woulda been responsible for hotel."
Cons: "The delay!!!"
Pros: "Nothing"
Cons: "Cancelled the flight two hours before departure. Weren't apologetic."
Cons: "Had to pay for entertainment. This was my 50th flight this year and first time any airline has no free entertainment. Probably will boycott united on future flights"
Pros: "Nothing"
Cons: "Not sitting by my wife."
Pros: "Polite and friendly staff."
Pros: "Nothing."
Cons: "Super delayed. 4 hours plus for a less than 2 hour flight. Unacceptable. Arrival at 3:15 am vs 11 pm."
Pros: "I overslept my flight and United was able to find the next available flight into Denver which helped me tremendously. The guy on the phone was very pleasant and helped so much."
Cons: "Boarding was disorganized and hard to understand. Flight was delayed because of paperwork that wasn't signed, which caused me to miss my connecting flight."
Pros: "There is no food essentially. No entertainment unless you have your own electronic hand-held device."
Cons: "See above."
Cons: "The plane wasn't very clean. And I might have liked another option besides a weird trail mix for a snack."
Cons: "It was freezing on the plane."
Cons: "Seats are too close."
Pros: "The Embraer ERJ-170 has comfortable seats!"
Cons: "More leg room"
Pros: "The seats in premium economy are comfortable and the the entertainment is good"
Cons: "Their was a 3 hour delay but is was for weather conditions in Newark"
Cons: "There was a delay with the flight. I wish there had been earlier communication about what was going on, i.e. Why it was delayed, how long will the delay be."
Pros: "I cancelled that flight... Hope my refund is coming soon"
Pros: "It was a small plane and it made up for some lost time in the delayed departure. The one air stewardess was also nice."
Cons: "Waiting for hand luggage on arrival slowed me down to catch my connecting flight. The flight was delayed to start with."
Pros: "The crew was nice"
Cons: "It wasn't on time to board"
Pros: "The seats were comfortable and spacious place were awesome :) The snack was very good, the best I had so far while flying. Service was great :)"
Cons: "I didn't like that because I was 4th group to get in the plane, all the space above my seat was full and I had to go put my carry-on quite further down. It didn't cause me any problem because my connection flight had a long layover, but if had not been, I could have been late."
Pros: "Friendly flight attendants, helpful staff at the ticket counter."
Cons: "Unable to check into both legs of my flight even though Air Canada used United for the first leg."
Pros: "Arriving."
Pros: "I was very nervous, but the flight attendant made me feel at ease."
Pros: "On time!"
Cons: "Old plane- lots of noises/raddles. Flight attendant not especially friendly, but that's ok? Wish United went direct from Louisville to Ft Myers. Need to add trip to Frequent Flyer Account"
Pros: "Boarding was fine"
Cons: "I paid for a non stop flight in first class. Flight was canceled and I got a coach seat in the back of the plane for my second flight which had a broken monitor that didn't work until the rough landing jostled it back to working order. Finding my luggage once I arrived was a nightmare."
Pros: "Nothing"
Cons: "Everything. I had a very tight schedule to visit my friends in canada. What was supposed to be a quick flight turned into almost 24 hours of travel and ariving 12 hours late. I was lucky to have 3 days in with my friends now i only have 2. Not to mention what was supposed to be an inexpensive trip turned i to an expensive one when you are forced to eat airport food after being constantly re routed. I bought my ticket based on ariving to ottawa in the morning this however was not the case. I will be seeking a refund."
Pros: "Nothing"
Cons: "Held up at check in because of understaffing. Long TSA line. When we finally got to gate wouldn't let us board. Then agent was extremely rude about putting us on a different flight. Have always flown Delta and am sorry I ever strayed. It will never happen again."
Pros: "service was great"
Cons: "There was no air circulating on the plane the entire flight. The plane was over 90 degrees when we got on. Everyone on the flight asked for the air to be on and we were told it was. No air was coming out of the vents. Horrible flight."
Pros: "Crew was friendly"
Cons: "A lot of turbulence for the 1st hour of flight"
Pros: "The piolets and staff were kimd"
Cons: "The airline kept delaying and canceling the flights with little to no notification, resulting in people missing work, connecting flights, and other important situations. there weren't many employees working at the airport to assist the people who were in unfortunate situations involving the flight, including myself. Overall it was a poor experience flying with United airlines, but that won't stop me from future planning."
Pros: "It was a pleasant surprise to find out I had a choice of movies to watch on my iPhone. Be sure to install the United Airlines App so that you can take advantage of this service."
Cons: "We were among the last 10 people to board and with the small plane size we had to gate check bags, but not a big deal."
Pros: "The flight attendants were great!"
Cons: "If you can tell that overhead storage space is going to be full so much as to pass out the green tags to check at the gate, why not just insist upon it? Instead of making me walk all the way to the back of the airplane and then having to walk all the way back to the front with the bag. Not everyone is familiar with all of your procedures without any explanation for them."
Pros: "Nothing"
