I needed to make changes to my flights. When I called customer service, they assisted me with care professionalism.

A bit rush for transit. Food and entertainment are not available

Wonderful and fast TSA checkpoint. The line was fast and our gate was close by

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

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

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

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

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

Terrible all around. Flight was late and airplane was very uncomfortable. The crew were unhelpful and hid in the back. Did zero work. No entertainment.

I booked and paid extra for exit door seats also pre paid for my luggage air Canada changed plains and I never got what I paid for and they made me pay for luggage again they also did this to my wife. They are the most unorganized company I have ever dealt with. I am sure I will never see the extra money I paid for the seats or the recharge for the luggage. They are subsidized by the taxpayers and don’t give a dam just a horrible way to do business

Nice crew - very small plane and uncomfortable, with no entertainment options…

Multiple change of the gates at Pearson, delayed flight was extremely uncomfortable.

Never made this leg of the flight since we rebooked through United instead. Did not make it to immigration/US custom due to the delay. Had to spend the night on our own dime in Toronto

YYZ air Canada security messed up which led to my kids missing their flight and having to go on a separate flight later in the day without the rest of the family. Customer service was horrible and have no sense of urgency or compassion for their customers. They refuse to compensate for their errors and making my kids wait hours in the airport. This isn’t the first time we have had issues with this airline and I won’t be flying with them again.

Cancelled flight had to fight for a hotel voucher and lost my upgrade. Not great business.

We were given an upgrade which provided more seat room and a meal. However seat designated overhead locker space was used by others.Boarding was delayed with part or the delay due to staff assisting diaablef individuals aboard. Personal observation would suggest that 3 individuals rorted the system. They used wheel chair access to the plane, boarding with family ahead of al other passengers, but required no assistance until boarding occurred. On departure 3 “disabled” individuals were seen walking freely near the baggage carousel. One person even assisted with a luggage trolley! The rorting is most likely widespread and not airline specific

Flight attendants were delightful, smiling, anticipating needs, and overall excellent. Pilots kept us informed and made 1 of the best soft landings!
