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 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.

Awesome, the whole way through. Thank you, this is the new Canadian Airline benchmark.

We were given a complimentary seat upgrade which was so unexpected but so lovely!

Porter was excellent. Boarding was a breeze. The seats were a little uncomfortably but the overall trip was excellent.

Only packaged snacks were served. It was a flight at lunchtime and a hot meal would have been a great.

Reserve check-in was very slow compared to regular check-in. Internet was slow

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

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

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Our seats were all the way in back of the plane,

Food choices were very limited. Taste of the dishes was average.

I liked nothing about this flight nor the incredible lack of service and communication on this flight from the Captain to every staff member. Arrogant, entitled and lacking any kind of basic customer service

Everything should be better, terrible flight and airport service. Delayed for 6 hours, flying around for 1 hr, and keeping us on a plane for another 2,5 -3hrs.

The plane was dirty. It appeared that Air Canada did not know vacuum cleaners had been invented. Second, the overhead bins were about 1/3 or 1/2 the size of "normal" bins. That was a problem. The worst was disembarking in the weather in Montreal. I have cold agglutinin disease. That means my red blood cells clump together and then are destroyed when exposed, even by breathing to cold air. A few seconds of exposure can be dangerous. I am now experiencing extreme fatigue caused by the anemia from that experience. I should have had more assistance descending a narrow ramp and then traversing, even if only a few feet, of icy pavement. The blowing snow penetrated my facial covering and has caused problems.

Good airport. Good entertainment on the big flight. Did not have a good way to prop up or mount my phone/ipad

I booked my flight ni November and was placed on standby? How does this happen. Flight was 1 1/2 hours late departure plane was switched to a smaller plane easy to tell this is a government run company they don’t care about anyone

Boarding was a disaster one person checking in 200 people took 25 min to check in zone 1&2.

Old, noisy plane, bad coffee, delayed. Flight attendant was very nice.

Boarding could be improved, no need to wait after a previous group is completed

We boarded 1.5 hours late. Long wait for the bags when we got to Mexico City. Long wait to get on plane with people mover truck. Friendly staff. They answered all questions as best the could. Such a long, long walk from the plane to customs. Thank you, Michael A. Burris Cambridge, Massachusetts USA

Delayed in Fort Lauderdale 3 hours , gave us $15 coupon for meals at 20:50, when most of the restuarant closed at 21:00.
