Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

The WiFi didn’t work and the seats are too close together. Very uncomfortable.

So so. Terrible aircraft choice for that leg of the flight.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

amazing! they were so kind and allowed us to sit on empty seats so we could stretch our legs and sleep good. Food is amazing as well plus dessert in the middle of the flight!

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

I can say I will not be taking this airline again any time soon. Seat were uncomfortable and too tight. Lack of chair screen and little overhead space.

American Airlines canceled the flight twice and was unable to facilitate a change of city for us after our travel plans became affected. We lost alot of money due to this and it seems like the airline was trying their best not to facilitate this. Mind you, I am a very loyal member.

Pretty good service and US Migratory officers providing services in Canada was awesome, because the arrival was quick and smooth

Rouge needs to offer seats with better pitch in economy. Many sick people on a full flight.

Overall, I would have to say my experience with Air Canada was mediocre their DC tens. Need to be updated not comfortable at all. Only one out of my four flights was decent. The staffing was very nice. Going through customs in Montreal was quick and easy. Air Canada has room for improvement with their facilities.

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

When we got to the airport for our flight from Chicago to Montreal which was scheduled for 2.00 p.m. they had no record of it and booked us on a flight at 3.30 very disappointing . We also had to pay 50.00 each for a seat. All things considered ,I will never book thru Kayak again. Next time I will only book directly thru Air Canada no second party booking Sue

My flight has been canceled and I had to cancel entire trip.

No food for a 6 hours flight! Plus very expensive to buy ! Sit uncomfortable! Awful!!!

There was no food on this flight. We had less than 1/3 full plane and were not allowed to spread out. Staff gave the story of the plane had to have all of us up front for 'balance.' Total bs.

There were changes to my flight with many email and very difficult to keep up with details of changes. I consulted Air Canada website that said I was to depart Casablanca at 9:35 but when I got to airport that take off time was delayed by 2 hours. That's 2 hours at an airport instead of bed. I don't understand why Air Canada website didn't show the change in take off like they showed the change in transfer. Do better.

I was delayed from Montreal to Tokyo for 3 hours and they didn't compensate anything
