Great! Personable crew. I love that they pour complimentary beer and wine.

I love the 2 seats per row. More room. The crew were excellent.

It was amazing although they did bump us up to the front which gave us more leg room and a meal. The service was great! The staff were friendly. :)

Overall very good... staff were friendly and helpful. boarding was good for the most part, but a little hard to get our carry-on bags on there.... I think people should be directed to keep their coats and small bags with them until all the carry-ons are loaded, and then, if there is space, they can put their small bags and coats up top.. makes it much easier to put baggage up. i loved the internet feature, but the entertainment was not there unless you have your own Netflix or similar platform. My chair did not recline, which was very annoying, and the arms won't go up near the isle, which makes it tough to get in and out of the seat.

Staff were excellant. Only snacks served. Some turbulence so we were offered Free beer or wine.

The staff is always great. Just the fact that our flight was the only one delayed from Halifax when all other carries were still flying. It happen a year ago out of Toronto as well. All others were flying but our flight got cancelled 1 hr before the time of departure.

The only issue had when i mentioned about comfort was the man beside me was on the larger side and took about 1/3 of my seat where i was pressed against the wall/window of the plane for the trip.

The check-in staff, boarding staff, and flight crew were all very friendly. Really miss the Porter lounge in Ottawa.

Thanks for giving a beer to everyone in the seat infront of me and then telling me that I can’t have one because they are going to land. I guess I need to pay for a seat and then pick one in the very front of the plane

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

The flight and crew were good. Departure and arrival were timely. Check-in was professional and helpful in Malaga on return trip (same on outbound trip from Toronto). The ad before ach program was punishing - specifically for the internet/data service with the content creator that was showed twice in each ad pod. It was so annoying I made an effort to forget the name and would not use the service. Provide an opportunity to fast forward or skip the darn ads once they have been initially viewed.

Extra attention to kids, thank you, we appreciate! Perfect landing

Over the wing seat at emergency exit only downside people using lavatory have no respect and wait in the space

Flight delayed any hour and couple of big gate changes

The pilot came out and chatted with the passengers. He explained why there was a slight delay. The crew was excellent. Very helpful. I had to buy meals for my whole family and they were in different seats, so the crew had to deal with that. They were very pleasant and accommodating and did a great job!

We were unable to land in Liberia. It was not the airline’s fault, but we had to be diverted to SJO.

We had things stolen from our luggage, we also were refused an upgrade on a flight that was not full.

When we left, it wasn't Great . People were drinking heavily, very disrespectful Extremely loud, the entire trip. I think the crew members, should have get their attention. Coming back was great.

I sat in the club. The seeds were fantastic. The meal was great and Entertainment was good. The crew was fantastic. I recommend it to everybody.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.

All male crew was just too woke for me. I felt like a sardine. I will never take a window seat or the rearmost seat again. I booked early and did not pay for seat selection and that was a mistake. The security at IAH was atrocious. I was violated and radiated as I was in a hurry to connect to my other flight. I may have lost items under the seat in front of me that I couldn't see nor bend over to look.

Liked nothing. As per previous segment it was delay delay delay.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

Was a normal flight but it was delayed, and there wasn't an explanation.

Pitch was very small. Knees were on the seat back in front of me.

Wonderful as usual except for other guests that were unruly and not kept in check by the Crew.

The flight was initially delayed, then cancelled. American Airlines says the cancellation was weather related, though the actual weather was not bad in both Washington and Providence and between. There were very few cancellations that day. In fact, AA2120 from Washington, DC to Boston flew with a minor delay at about the same time. So, the weather somehow affected only this particular flight AA5230. The next available flight was the following morning. The American Airlines refused to reimburse accommodation (hotel at DCA)

Fine. On time, cabin service was fine, bag arrived. All good. Flying into DCA so did not collide with any helicopters, which is also good. Horrid incident that could have and should have been prevented.

Good experience but the snacks are not gluten free, so I cannot eat them.

Standard. No different than a discount carrier on a short trip.

Everything was great. Boarding, early departure, early arrival, and deplaning were smooth. Smooth flight.

I blame kayak for my last trip to dca. Kayak cancelled my direct flight and put on a one stop flight and made lost whole day from my vacation and had not even refunded my ticket.

I flew out of Reagan National. My flight was delayed, delayed, delayed, and then canceled ...THREE TIMES over TWO DAYS. Staff were seemingly not empowered to provide information on why the flights were screwed up. A real nightmare.

Flight was delayed but the real issue is how long we sat after boarding. Space very limited for an overnight flight and seatbacks didn’t recline so it was almost impossible to sleep.

The staff made sure I was comfortable, moved me to a better seat with more leg room

Somehow, my booking was under my preferred name instead of my legal name so they almost didn’t let me board the plane at LAX. This problem should have been notified to me when I was still in Toronto.

When arriving over 2 hours early to check k in at Charlotte airport I was told I would have to check my carry on ? Apparently the flight was full and may not be room. I was not given a choice and the agent was quite unpleasant about it. I am a senior amd was not comfortable me having to worry about my bag being lost vut it didn’t seem to bother him. There were lots and lots of people of all ages in line when we boarded with carryons and most larger than mine .the rest of my journey was pleasant vut this was totally unacceptable.

The layover was 6 PLUS hours and we were only given a $15.00 voucher. We missed our first activity in Quebec due to the delay.

Miserable staff as it was a late/delayed flight and crew wasn’t in the best spirits. Completely understood as neither was most of the passengers. Still unacceptable l.

It was a short flight, and no entertainment. That was not a problem for us, but there is no option for "not applicable". There was a bit of turbulence, so there was no food service.

the fact air Canada changed my flight from 850 PM to 815 AM with zero regard to the plans i made that last day, the cost i lost out on as things were non refundable amd shortening my first vacation in 7 years sickened me. when we purchase a service thats whats we expect. when we want to change the service we have to pay for that option but you do whatever you want . i called accessibility dept as i have a cpap and an implanted loop recorder first person said no problem just let security know you cant go thru scanners. then i got an email saying i had to fill out a fit to fly form . which again there was NO need to have that none. But that cost me money and time to have a doctor fill it out. then when i went to check in online i was declined i had to see a person at the airport instead. i couldnt get my boarding pass like everyone elseso here I was contacting air canada so I would have a easy travel experience and it ended up being a nightmare with more work for me, more cost and time. the flight itself was great the nightmare around it i will never subject myself to again. i tried to stick with supporting Canada but Air Canada was not worth supporting. very disappointed especially with a dept that is supposed to help disabled people not make an already challenging event not worth going thru at all.

Most courteous, helpful employees and all flights were on time.

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was
