I am frequent flyer, means tried many different airlines in past.
Booked premium economy to Toronto, as my departure was in the morning and I did not need to sleep.
Taking back in the evening I decided to upgrade and found out it was not worse money. Seat and bad was extremely narrow. I am normal size, h180 cm and 75 kg, but could absolutely not move and turn around.
Food very average.
Having my business ticketI went to business lounge, but could not enter, as I was not “normal” business passenger.
First I took it as a bad joke, but it was very, very serious.
Many airlines make very complicated rules and at the end they loos customers.
Never Air Canada again.
