Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

headphone jack didnt work for the first flight and not much variety

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Not as good as expected Air Can needs to improve totally rated on internet as worst

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Everything was good. Flight was on time, luggage pickup was quick. The staff were great. Could not ask for anything more.

lots of delays the crew were unclear about where to pick up my carry-on, which they took from me to check in on the plane.

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

There is not enough space between two chairs and raws.

Terrible. 3 missed flights and 24 hours delayed with lost bag and promised $100 compensation from United and absolutely nothing from them…

Seats were comfortable, flights boarded easily, arrived early in Toronto and on time in Nassau

It was a lovely flight. Very attentive crew, comfortable seats, good food and entertainment. Highly recommended. Only difficulty was with their app.

Terrible. Flight was delayed for hours and we ended up arriving at our home at 4am after 20+ hours flying.

Flight was cancelled around 45 -1hr minutes before scheduled take off time due to mechanical issues we hadn’t even boarded yet. Had to reroute to Orlando so someone had to drive 2 1/2 to come and get me… the alternative was go through Toronto and get a later flight which didn’t work for my schedule. The flight attendants barely gave anyone a smile…not the same as flying when a client/passenger was important. Very disappointed. By the way I have never ever made a complaint online about any company with feedback…even when I probably should have. The only good experience was the boarding desk associates who were very professional and got me on another flight with my checked bags…very nice team.

Actually as my experience with air Canada from Canada to Newark it was crazy for me because it was a lot of delays which for me it shouldn’t be like that, but I was able to coup with it so that was my experience I hope next time they will do good on that thanks.

Boarding was challenging as we had to use the stairs from the tarmac. Stairs are okay but a roller bag makes it challenging.

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not
