The food selection has been better in the past but due to Covid it is understandable. This particular flight did not have any entertainment and the Air Canada App did not work to access movies.

my flight was cancelled and I was not notified of this. in fact I got a confirmation on September 7, 2021 from Kayak and when I called to check on seats that is when I was told that flight was cancelled back in April. I had to spend the next 3 hours scrambling to change my entire trip and still have not received my entire refund for the cancelled flights.
