Super unproffesional flight . Flight attendants were unproffesional. I could hear them gossiping about theor boyfriends the whole trip

The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

The ticket price was reasonable, food was okay, not the best. I would use the service again.

Actually the flight was on time. New plane, food was okay but not great.

Old plane, hard seats, 1.30 hours delay, while seating on the plane waiting for departure.

Great boarding. Everything was on time. Plane was a bit old and the crew could have provided better drink service.

Crew was pleasant. Aircraft was very dated and uncomfortable for our nearly 4 hour flight. We were in row 17 and they ran out of purchasable food by the time they got to us.

Compagnie efficace et bons prix. Les sièges en classe club pourraient être plus confortables.

Lisbon, make sure to get food , coffee prior to going to boarding gates as there is no food being served after. Only vending machines. A lot of check points to get to the boarding gates. Not enough seating for passengers waiting to board. Crew was very courteous and kind.

We could not check in early, I think because we purchases through a third party, therefore once we got to the airport, no seats together, and only middle seats. Will never do that again

It was awful. For a 37 minute flight time,we had 1:30 hours delay. If someone had a connection flight he or she couldn’t reach for sure. The only positive point was online check in.

Not full, so lots of room, which is really the only thing that can make flying economy more comfortable. Direct to Toronto is great! I didn't eat or use the entertainment.

You do not have a space for flight cancelled. BUT!!! Air Canada handled it great. Was booked on another airline for the next day. The original flight was booked solid. But he precheck by the maintenance found a mechanical problem and the plane was not safe to fly. It was an inconvenience to have to wait until next day but I would rather arrive safely.

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.

I had written all my complaints on my trip from Grand Junction to Denver so I will repeat it here! I was absolutely appalled that I had to pay for a regular seat that I choose 24 hrs before boarding! Also I checked my large bag which I had to pay for as well, and by the time I boarded all the room in the bins were gone so also had to check that one. I noticed people pulling out oversized suitcases, bigger than the measurements stated for carry on, and also large pack packs stuffed full! So these people were taking up 2 or 3 spaces that the rest of us should have been able to use but couldn’t! NoTV on the flight! Thankfully I had downloaded the United Airlines app and was able to watch movies on my phone. Don’t remember the last time I flew in a plane with no movie screens!

The crew was friendly, the seats are too small. Air travel is barely tolerable anymore.

Not much food available, not able to choose seats to be near each other, tv did not work

Food was icecold or frozen including breakfast. Hopeless service. Rude crew.

Catering strike impacted food service. Snacks & water were available. Gate staff did advise "if you want food on the plane you will need to bring it aboard". Entertainment system not available on this flight. Boarding was early. Departure was early & arrival was early.

The flight was very uncomfortable and there was no snacks served for the 13 hours international flight. In addition, the flight was delayed 3 hours
