I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

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.

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.

Liked nothing. As per previous segment it was delay delay delay.

Basics were there, but a 5:15 flight with almost no food ans no entertainment, it is quite long.

Extremely uncomfortable sitting in a small space for 2 hours, especially for older people. Understood it was circumstantial.

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

We left really late. Things that were out if anybody’s control I guess.

Excellent as always. Service was excellent and fully bilingual. Cannot complain .Will travel again. Always have and will continue. Highly recommended.

Cold processed snacks for $$$$ Screaming children of family of 5 out of hell, nowhere to hide, strapped into a chair forced to listen to 3+ hours, crew completely lost control….Check in is completely automated with staff looking at you like you always were supposed to know how to stick your luggage sticker. The airport has no usb or usb-c charger you are forced to buy a cube for $20-$30. Somewhat disappointing well it was the first and the last time

The best thing about the flight was the cabin crews in the business class. The young Asian lady was just fantastic!

It’s a good airline. Polite service and good communication.

We ran into trouble in Montreal. Exited the plane and Air Canada was excellent getting everyone quickly to their destinations. I give Air Canada a 100%.

The flight was delayed and we would have missed our connection. We had to switch to a different airline in another airport

Multiple delays and flight cancellations meant that I arrived five and a half hours late at my destination. There was limited communication from the airline. The airline left my checked bag at my departure city and stopped tracking it almost immediately. The airline has made no apparent effort to return my bag despite filing a report, and has provided no communication or ability to check on the status of the bag.

I'm 6'8" (2.03m) so more legroom would alwqys be appreciated, especially on long international flights. The food choices were underwhelming.

1didnt have wheel chair I ordered wheel chair in my ticket flight

Flight was over an hour late departing and when we got to Montreal there was no gate and so we had to wait on the tarmac for over an hour!!!!!

I like the tv show the seat was ok and the crew was awesome
