Delayed on the way in 2 hours!!! And now on the way home delayed then cancelled!!!!!

Delay in luggage again for the second time of the trip. I would not advise using air Canada or at least I will never check in a luggage. Luggage issue overshadows the nice crew members unfortunately.

The baggage drop-off for Air Canada in Toronto for passengers flying international was terrible. One of the worst experiences I have ever had. The line was ridiculous; there was no one to help facilitate people avoid confusion, and the baggage system for the line I finally ended up in had to be re-booted right as I got to it.

Flight got canceled. Instead of the booking me for the next flight at night I was booked for the following day at a later time. I was able to fly out that night because I had to call and deal with a human!!!

No charger and no entertainment on the way back. The plane's super old-like 80s old-with zero TVs. At least the free Wi-Fi works, so definitely bring your iPad. Also, no meal on this 7-hour flight.

Horrible! Rude flight attendant, barely any service on such a long flight. I wouldn't recommend Air Canada to anyone.

Canceled my flight in March and have been waiting for 3 months now without the refund after it was promised

Smooth ride but I wish they have better food selections.

At 6'2" the seat space was very cramped for economy. Otherwise good.

Not being allowed to use anything other than visa to buy food is embarrassing and upsetting. I have a debit card which has actual money on it to be used immediately but they only accept Visa which has theoretical money. I was hungry and they had food and I had to go without while Everyone Else Around Me Ate. It was horrible and unfair.
