Enjoyed the A330 comfort, and the inseat entertainment. Horrible disembarking experience. No gate when we landed to sat on tarmac for 40 minutes, and missed my train.

Cancelled flight, had to rearrange plans independently and no vouchers offered

This was my second leg of my trip and was delayed so was worried about my connection in Montreal. Still hungry so on boarding I asked a flight attendant if I could use my $14.00 voucher on the plane for food as I was starving. She said she would check and let me know but she never came back. So no food again as none was offered. Had to get my bags and check them again and that was ok but don’t understand why I had to go through security and because of them almost missed my flight. No food offered nor possibility to purchase food so still hungry and just watched a movie and hoped I could get food when I landed. Was able to use the $14.00 voucher to buy something and had my family bring food as I was now starving. I’ve been travelling on AC for years and this was my worst experience ever. After our flight got cancelled in SXM and was told the staff there didn’t work for AC so couldn’t do much to help us was not a good experience

When I came in the front door in Montreal airport I didn't know where to go, first time traveling. Signs were not directing me.

I had a great experience at YUL Air Canada. The service was top drawer as I needed help to board.

Disappointed my flight was delayed to TO as i had a connection to make. Ran through the airport I made my flight but I initially had 1.5 hours to connect. Unnecessary stress!

The speaker flight attendant talked over was way too loud. Hurt my ears -had to take out hearing aids.

The flight attendants were lovely - very warm and kind. Really appreciated it.

The Q400 plane is getting old and very noisy. They should allow the quieter jets fly onto the island.

Went on an earlier, standby flight, but was delayed so we only save 30 minutes getting to Toronto. AND we were in business class on our original flight but had to go in economy on the earlier flight because pilots and crew “had to” go business. What?!?! The paying passenger (I am Super Elite) has to go economy so they can dead-head employees? That’s messed up. As in my other posts, I only take AIr Canada because there is little other choice for the destinations I need to get to. But I am not proud to show my Super Elite tag on my luggage.
