Overall a good experience as this leg I was in Business Class. The Lounge was amazing with a view of the planes. The flight attendant spoke way to quickly when giving the information for take off and landing and it would be of no use to a first time traveler. Overall a great airline to travel on.

Overall a good experience as this leg I was in Business Class. The Lounge was amazing with a view of the planes. The flight attendant spoke way to quickly when giving the information for take off and landing and it would be of no use to a first time traveler. Overall a great airline to travel on.

Smooth on-time flight but NO AC in the middle of the cabin. Business Class and the rear of the cabin were too cold but mid-cabin was stuffy and hot with virtually no air coming out of the ducts. Made for a very long and uncomfortable flight.

Air Canada’s problems are not staff related by and large, no. The problem is tiny jets between the U.S. and Canada - yes, believe it or not they are still “international” (just ask our own Mango Maniac in power in the U.S.). The little aisle is compounded by a design flaw of a “dog leg” starting at seat 12. Woe be unto you if you sit here as passengers and attendants do not have sufficient room to not hit you in the face with backpacks. One thing I will say very positively about Air Canada is you still provide pillows and blankets on transcontinental flights to all, not just the elites. Your tiny improperly designed jets are also a problem flying city to city within Canada also. One can only say you remind us of a “Jet Blue” or “Spirit” experience. Also your luggage space is downright Byzantine! We will endeavor to avoid you and use other U.S. carriers, albeit charging more.

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

The airplane has been replaced and late night layover have been extended from 3 to 7 and the only compensation was a $15 food voucher after most restaurants have been closed, not helping with children after a 18+ hour international flight

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

They are very proactive and made our boarding easy and always notified us about any changes well in advance.

This flight with a lot empty place , and I have more room, feeling comfortable.

Flight was good, breakfast could be much better. We had come from a domestic flight on the same aircraft and the domestic flight was much better regarding service compared to this international flight.

I accidentally touched a cabin steward as she passed by and she reacted harshly yelling in a loud voice “don’t touch me”. It was embarrassing and uncalled for. I would characterize a few of the cabin crew as pretentious and aloof. Not at all what is expected. That was the first leg of our trip from Montreal to Munich. The second leg from Munich to Nice was more in keeping with the service I expected.
