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.

Flight was actually on Air Canada. The flight itself was fine. Nothing special. Food was pretty pathetic except for cookies. They offered plenty of food and drinks but just wasn't very good. Even for airline food.

Boarding experience was smooth. Flight attendants were friendly and helpful. Entertainment system on the Houston-Edmonton flight did not function for passengers on the left side of the aisle. On the bird's eye flight from Quito to Houston, they should not serve a meal. No one needs to eat after midnight and it is disturbing for those passengers trying to sleep.

Excellent service despite turbulence during the flight. Flight attendants were remarkable!

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

Delay and keep changing gates. I have to run around from B to C then to E.

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

My suitcase was completed destroyed. The top part is broken and unusable now.

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.

Abandoned me in hallway in a wheelchair… which I asked for because I sprained my back. After waiting in the hallway, I decided to walk the rest of the way since someone respecting me up.. My experience with the united was totally the opposite. Wheelchair access, propped swift and save me a lot of grief. Air Canada totally disorganized.

Bad experience boarding and flight got delayed didn’t make it to my next flight

The food on the trip Toronto to Athens could be better: the chicken didn’t taste good.

Conflicting information provided about baggage allowance. One screen said I had a carry on and another said I didnt.

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.
