Cons: "No one told us the only inflight entertainment option was streaming via their app, until we were seated on the aircraft with no access to wifi."

Pros: "Prompt arrival"

Pros: "The agent at check-in was very friendly and helpful."
Cons: "Flight was delayed, so missed connection. As it turns out, Air Canada was aware all along that we would miss our connection; however, they still had us board. 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."

Cons: "DELAYED FLIGHT DIDN'T HOLD MY CONNECTION - MISSED BY JUST 15 MIN SEATS NOT COMFORTABLE - PREMIUM ECONOMY NOT WORTH THE EXTRA COST"

Cons: "Arrived in Montreal six hours late"

Cons: "With basically all my flights on Air Canada, there were significant delays. The delays on this flight caused me to almost miss my connection. I had to run full speed to make it to the next flight, and the attendants on this flight were very terse announcing as we were landing "Do not ask us about your connections; we have no information. Do not ask us about your luggage; we have no information" With other airlines in the past, if I have had a flight delayed by an hour, the attendants have announced where I should be headed for my connection, or have called ahead to the connecting flight (if within the same airline" and asked them to wait for us. I didn't feel that AC did anything to help make up for the fact that my flights were so late. Almost ally other AC flights on this trip we're also delayed."

Pros: "Friendly folks"
Cons: "My flight was first delayed, then cancelled, and there wasn't even bad weather at either airport. I still don't know why the flight was cancelled. My alternate flight had to be from a different airport and that flight was also delayed. I went from a non-stop flight to a flight with a layover... a 7 hour layover. Was not fun sleeping at the airport. On top of that, I had paid to select my seat and it wasn't honored on the flight back. Somehow I was unassigned because of the flight change during departure but I was still charged."

Pros: "Overall good flight in terms of smoothness, safety, timeliness, etc."
Cons: "No enrertsinment without downloading google app for phone or pad. Short announcement about this made shortly before flight and we did not react in time to do it. Thought I would read but overhead lights broken; complained three times before fixed."

Cons: "Our direct flight to Montreal was canceled due to mechanical issues. The rebooking process was discombobulating and we ended up arriving at our destination after the rerouting that was stressful and ensured that we lost a whole day of our vacation time. Our flight back the entertainment system in our seats did not function."

Pros: "Decent movies."
Cons: "I separated from my 2 daughters and husband because they did not allow me to pick seats or check in online. I was stuck in the seat immediately in front of the stinky bathroom in a seat that didn't recline, had no hdmi charging port and was pretty much continuously crowded by bathroom-goers. In fact, so many bathroom goers grabbed the seat in front of me that they touched my movie screen about 7-8 times, causing the menu to pop up and interrupt the movie. Otherwise, the food was gross and one of the flight attendants was very grumpy."

Pros: "The flight arrived about 30 minutes early. Also, it left a little late. For me, the less time on the plane the better."
Cons: "Guy next to wanted to charge phone a laptop in USB port in front of me b/c his was our of order. This worked out OK but in a small space it's not so good. He was bare foot too. Take of your shoes but wear socks, please....Plane was not hot, actual a litter chilly."

Pros: "plenty of room, media player, wifi, nice selection of snacks and meals."

Pros: "Quick professional services"

Pros: "The counter employees as well as the people who helped me navigate the airport ( I am disabled) were very helpful."
Cons: "The crew on the plane seemed very overburdened and somewhat annoyed by passengers. Maybe they were having a challenging day. I don't know. I didn't even want to ask for a glass of water."

Pros: "Service food on time flights"
Cons: "No movie for such a long flight."

Pros: "Seats"

Pros: "clean, polite, helpful crew"
Cons: "obtaining boarding passess via smartphone"

Cons: "Our flight was over an hour late getting to the airport in Morocco and when there we were left standing in the jetway after scanning our tickets for a good 30 minutes. The flight was so delayed, many of us missed our connecting flights and had to be issued later flights. I was originally booked to fly out the next day, which would NOT have worked out but was booked instead for 5 hours later. I stood downstairs for 2 hours trying to find my baggages, however, they never came where they were supposed to come out and I received 3 different answers on where they were. "They're at carousel 5," "you don't have to get them they will be checked to your final destination," no they're at carousel 3, so you can grab quickly and recheck upstairs." My bag wasn't at any of these places. I finally found a nice air Canada agent who took the time out of his day to actually go to the back and check on my bag to which he returned 10 minutes later with it. It was just "circling around back there" with nowhere to go. Had I not been persistent, my bag would not have made it to my final destination. I wish the story ended there but it does not. After a 5 hour wait, I sat at my gate which continued to say "American Airlines" I asked the gate if United Airlines flight was still leaving from there she just stated she "had no idea" frustrated, with no gate to go to with a flight leaving in 1 hour nobody seemed to know where our new flight was boarding. After 3 gate changes we were finally able to board our flight to D.C. I am sorely disappointment in both Air Canada and the YUL system. This would be my second time flying this way and both times I have had issues. It's too bad. I do not plan on doing so again."

Pros: "I liked the friendly crew members"
Cons: "1. Could not reserve seat on the return flight and still got charged for it. 2. My seat did not have the new outlet for phone jack and USB charger. I had to use old headset outlet on the arm-rest which did not work. 3. Planes delayed on both directions."

Pros: "Didn't take it"
Cons: "Customer service in Toronto did not know how to get us to Venice before our cruise departed. Wild goose chase sent us on a one hour, $26 train ride to Milan central station where we learned the train air canada told us to take didn't exist. Suddenly forced to take a 2.5 hr, $500 cab ride to Venice."

Pros: "It is one step back from Air Canada Rouge but it is the best airline flying to LA"
Cons: "I missed the blankets and pillows"

Pros: "Air Canada Rouge business class is excellent I would recommend it to anyone"
Cons: "There was nothing that I did not like"

Pros: "Comfort, decent entertainment selection, crew was pleasant and professional, boarding was smooth"
Cons: "Food = bland mystery meat entree."

Pros: "We had to sleep on floor of Toronto airport all night"
Cons: "Bumped from flight no compensation"

Pros: "Good legroom and entertainment options, on time. Enjoyable overall."
Cons: "Food showed British heritage -- stodgy, boring, overcooked. The bathrooms were dirty and out of supplies after a while."

Pros: "I hated both my trips with Air Canada. I payed extra for a better seat and the one I got was dirty. The tv was NOT working. On top of the 5 hours delay, I hated all the experience. The attendants messages is never clear and focus. It's like Air Canada is employing teenagers with NO work etics or professionalism. I am a frequent flyer and will NEVER flew with Air Canada again. The cheap ticket is not worth the cheap aircraft and cheap service I received."

Pros: "They arrived on time. Not much else."
Cons: "Over 4 hour flight. No food (not even pretzels). A few old movies. Flight delay with no communication. I only noticed when I was checking in at the kiosk and noticed that my one hour layover was now a 5 minute layover. Rebooked. When I arrived at destination, no notice that next flight was delayed, even though it was over 3 hours late. Thought I only had 1 hour to go through US immigrations and customs. Ran to the other end of the airport to be on time. Aircraft wasn't even at airport and flight was over 3 hours late. They couldn't have posted that so we didn't have to run across the airport? Changed gates, but no announcement. One other flyer was looking at the board and called out to the group waiting that there was a gate change. Left Vancouver at 8:00 am, arrived in Boston at 1:30 am. Won't fly with Air Canada again."

Cons: "Horrible to fly Air Canada"

Cons: "There was absolutely nothing that I found to complain about"

Pros: "comfortable clean and overall a pleasant experience"

Pros: "The seats were spacious and the electric/USB outlets made all the difference! By the end of the flight, my phone was charged and I was ready to see Montreal!"
Cons: "Paying for seats."

Cons: "Screaming kids right behind me for 3 1/2 of the 4 hour flight"

Cons: "Didn't accept my carry-on that was always accepted before with all airlines.At least from Mtl to Quebec,i would have been able to do it.I will reconsider travelling with A C ???"

Cons: "What a mess. Every DELTA flight I have been on in recent months has had terrible delay issues - I'm cancelling my credit card."

Cons: "I was dozing when the attendant came around- as a result went through whole flight without water!"

Cons: "Everything costs extra: picking seats, pillows, blankets, no Economy Plus for Star Alliance elites, any food, etc."

Cons: "It was 3am and my boarding pass wasn't bright enough on my phone. Instead of politely asking me to go print out my boarding pass at the check in stations, she yelled at me and told me I was holding up the line"

Pros: "Loved the plane."
Cons: "I tried to get business class it was full. In general, I don't spend for business class because AC BC is so poor (horrible food, iffy seats, broken entertainment systems). But this plane was different, unfortunately I couldn't get on."

Pros: "The flight attendants were very professional and nice."
Cons: "The flight took off late and did not make up the lost time during the flight."

Pros: "Arrived early at check in counter and was offered to catch an earlier flight"
Cons: "Was not able to use a toddler booster for my daughter"

Pros: "The ice cream and the one woman in customer service that actually seemed to care."
Cons: "My husband and I were flying to Italy, on the first leg of our flight neither of our screens worked so we had six hours with no entertainment. They gave us a card to make it up to us but (wisely) don't tell you what it is for. It turned out to be for 10% off your next flight if you book it through their website within a year. Useless. On our return flight we were delayed on the tarmac for over an hour with no air conditioning, they originally said they were waiting for a signature but then said that there was something wrong with the engines that help us take off, then the cabin filled with a fuel smell, then they said they had brought the wrong item for the repair and we were waiting for the correct one. When we finally took off my husband's screen didn't work yet again and this was a 9 hour flight. The flight attendant said that some of the screens hadn't worked for a while ( probably cheaper to hand out useless discounts than to fix them.). We received another 10% off card, which we cannot combine or transfer, again useless. We missed our connection because of the delay, they booked us on another flight but because they didn't tell us that we had to pick up our luggage or where (it was on a different carousel than the rest of the luggage from our flight) and that we had to go through customs we (and many others) missed that flight too. We finally got a flight out the next morning and they put us up at a hotel. We both had to miss another day of work and it was quite an ordeal. My husband's screen worked for almost all of that last flight before it seized up. We didn't bother to report it that time since another 10% off coupon wasn't going to do us any good. Overall it is concerning that Air Canada doesn't seem to be maintaining their planes in optimal condition and that their idea of compensation involves them making even more money from me. Never again."

Pros: "The flight was on time, boarding was well-organized, the service was friendly and helpful."
Cons: "The line to the washroom was quite long - there were only two washrooms at the back of the plane."

Pros: "Everything was ok ! I love late departures"
Cons: "From Cancun to Mtl, we had to wait 2 hours before boarding!"

Cons: "The crew"

Pros: "I liked the flight when I got off the plane because it was over"
Cons: "The whole experience was horrible, the landing, the food, the noise, the unconfortable seats, the plane was too hot and especially the bad landing...never again...it was the worst trip I have ever taken and I fly 2 times a year."

Pros: "Entertainment selection was excellent and the liquor selection exceeded expectation. Very smooth flight."
Cons: "Didn't give us US customs forms, had to ask, only got one, had to ask again, and then rushed to fill them out and THEN customs threw them out and we had to do everything on the computer. I would think that the crew would be familiar with this process at their home airport and not waste our time. Also, no one could tell us if we would have to go through security again and if we could buy any liquids in Paris duty free to bring home due to the liquid rule and going through security. Just a wildly uninformed airline (asked our crew and other AC officials) they couldn't answer a few simple questions."

Pros: "Prompt, courteous staff, clean ."
Cons: "Don't love having to watch movie on a phone. Would prefer screens on plane."

Cons: "I did not like that I could not use my own ear phones to watch movies during my flight. Also they do not offer visa debit on flights so I was not able to purchase ear phones. Which made the 4.5 hour flight long. And my head rest was very uncomfortable, I am short and it pushed my head forward too much which hurt my neck. It would be nice to have the option to remove it. Also on a 4.5 hour flight they should offer free little snack like peanuts or a fruit cup."

Pros: "The staff was very pleasant and accommodating."

Cons: "Boarding was delayed due to crew unavailability. Entertainment did not work due to connectivity issued during flight. No cookies nor snacks were served vs outbound flight where they offered 3 snacks!"

Pros: "Good crew"
Cons: "No wifi"

Cons: "I ran to the gate from my previous flight, but it turned out this flight had been delayed. The flight boards and United app didn't show that though."

Cons: "I was flying with Air Canada. The UI for watching movies was not good, it had a hard time to respond to the inputs. It was also hard to move the videos forward to the part I needed. Plus, the audio wasn't working well with my own earphones."

Pros: "Getting home."
Cons: "It was an older airplane. For a long flight from Montreal to San Francisco, a plane with more room would be more humane. People were lined up for the bathrooms most of the trip since could not use the small first class bathroom. If one wanted a meal, it was one you had to pay for. Broken monitor"

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!"

Pros: "There is nothing to like about Air Canada's Rouge service. Their sardine seat layouts are amongst the worst in the industry."
Cons: "1. Seat comfort. 2. On-time departure. 3. Boarding Procedures. 4. Pre-boarding announcements."

Pros: "On time departure & arrival"

Pros: "Pleasant flight crew and comfy seats, even in coach."

Pros: "Clean plane, comfy seats and friendly staff"
Cons: "All was good. Didn’t have any problems."

Pros: "Flight on time"
Cons: "Travel plans will be impacted due to lost luggage"

Pros: "the comped hotel"
Cons: "Improper handling of situation. There was flight scheduled later, but CS agent kept jerking us around. By the time I reached the United counter, the next flight was full. My total flight time was 36 hours. I still can’t believe that the pilot was missing. Worse yet, the agent at the gate could have made things much easier instead of telling everyone that a pilot was on his way to the airport."

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."

Pros: "1 hour late"

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."

Pros: "Nice attendant, food OK, no delay."
Cons: "Internet costs"

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: "Polite and friendly staff."

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: "Put us up in the hilton."
Cons: "Told us to run across the airport just to get there and they already shut the doors 20 minutes before the scheduled departure. had to miss another day of work..."

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"

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."

Cons: "Flight delay"

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: "Snack delicious"

Pros: "Nothing"
Cons: "The flight was delayed more times than I can count & cancelled around midnight. AWFUL!"

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: "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."

Cons: "The plane was tiny and the seats were tiny. Could not carry on a bag and it took a long time to get the bag back from having been gate checked."

Pros: "On time"

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: "Quick flight and also very nice people working. They took good care of us for our short time with them."
Cons: "I have no complaints about this flight. It went very smooth."

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"

Pros: "Nothing."
Cons: "Everything."

Pros: "Nothing"
Cons: "Flight was 3 hrs late leaving Louisville and there was no acknowledgement of that or apology from the United staff."
