Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

Very nice and clean plane. Transit time between flights was tight though

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

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

The plane used to go to Chicago was a bit outdated and needed a refresh

The check-in and passport submission was complicated and repetitive, due to the poor communication between Air Canada and United. There should have been a single set of instructions and a single questionnaire that provided the data for both airlines.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

Internet was not working for a bet . Hard to order food with our credit card because it was not in your system .

Booked economy through United - air canada treated it as standby and was almost refused boarding.
