I did not like the fact that the first leg of our trip from Canada to Nassau was delayed by 3 hours so we missed our connection to London. But yet the follow day our flight never left Canada until about 1:10 the following morning. Only 2 of the 3 persons in my group was issued meal vouchers. We lost a day of sightseeing in London. On the Canada to Nassau London I requested a cup of water which the stewardess shrug me off and never brought it

Unfortunately, my experience with Air Canada was not as great as I had hoped. The flight attendants were not very friendly or welcoming, which made the overall experience less pleasant. I expected better customer service and a more positive attitude from the crew. I hope Air Canada takes this feedback into consideration and works to improve the passenger experience.

great flights both ways on time both ways.staff(ladies) where great at check-in.

Crew attitude and attentiveness. Comfort of the seats. Entertainment options.

Was disappointed when landing in Canada was made to wait for over 1 hour with several other parents and babies for our strollers . The expectation was that the gate checked strollers would be there when exiting aircraft. This was not the case we were told to walk to a point and wait for them . After being left there and not being updated we were met with very hostile and rude air canada staff . There where no apologies or understanding even though all the children where very uncomfortable and the parents very frustrated as you can imagine . Instead the air canada staff at the airport where very rude and made an already frustrating situation much worse instead of trying to assure the parents that that were making effort to fix the situation. One gentleman in particular was very rude to some parents telling them to move when they were simply seeking information. He made the other parents including myself feel very uncomfortable. He also told a gentleman he was capturing images of everyones boarding pass when this was untrue as he was only taking a photo of the gentleman pass which was strange.

Had to cancel the flight because there was a 14 hour layover before the flight. Unacceptable.

I wish they gave the earphones earlier rather than when we are already in flight.

We were a little late pushing back ,but arrived a head of time.

The flight is very short, may be a little snack can be offered

They canceled my flight last minute, no hotel provided and they rescheduled Sunday night, hope they refunded some money
