The Carry-on luggage that approved by TSA and all other airlines,- always an issue with Air Canada. This is inappropriate as my carry on suitcase meets the requirements however it always asked to check in on AC flight on the gate. Yes I have it for free, but it takes extra time to pick up on the carousel. Apparently it fit the overhead space, so why AC has this issue all the time?

The terminal this flight boarded from was so far away, poorly temperature controlled, and generally uncomfortable. The plane was small but the flight was short, so it wasn't so bad.

Seriously need to improve the time schedule and the plans

Great TV, easy boarding, wonderful ground crew and flight crew.

Rude Customer Service at checkin, 90 minute limit in flight check in is too strict. I was in line for 30 minutes because of slow/insufficient workers. Somewhere I got to the the counter of course the employee warned me about the 90 minutes. People were cutting the lines. No one did anything.

Everything was great. I really like how they had their safety film set up showing you the beauty of the country.

I liked the early check in. Flight was a bit bumpy due yo weather. Overall, everything went well.

Limited snack options cause the snack vendor was on strike

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic
