Horrible crew, horrible seats configuration, ridiculous space in the toilets, Air Canada is no longer a option.

Flight and attendance were very good we had 2 hour delay that took the shine of it

Be careful about the bad policy and when purchasing seats

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.

This is a great non-stop YVR-MIA. Very comfortable plane, and no transfer through a city that gets major winter weather!

Terrible canceled flight and lost my luggage. Flew me to Halifax. Tgat flight was delayed, had to spend night in airport chair.

My seat was not comfortable. Flight was smooth. Regretfully we had two delays before takeoff

My seat was covered in vomit and I will be reaching out to Air Canada

3 hr delay at the gate while they were doing maintenance. Next time, do not board passengers while maintenance is being performed

Baggage delayed we had to catch our cruise without any clothes 😒
