Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

So far so good but food and entertainment are not available for this flight

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

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

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
