it was hours late with a fake story about the high wind

I had a fine time, but when I booked my tickets, I chose my seats. I had picked specific seats. When I checked in, I learned that my seats were gone, they'd put me in random seats instead. I didn't care for the flight from Toronto to Philly, but for Haneda to Toronto, I was very uncomfortable in a middle seat instead of an aisle seat.

Air canada definitely needs to get better with their timing for flight as our first flight time was changed and moved earlier and flight from hnd to yyz was delayed by like 1.5hrs

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

I like the free air Canada wifi and being able to watch things on there. The basic snacks are good, just wish I could have both. If I’m being really picky, the flight attendant who filled my drink, filled it half with fizz and didn’t take the second to let it go down and add more, so I got maybe half a cup of pop.

Seats too small and too cramped, I have stomach cancer and I threw up after the flight . No advance boarding for disabled people. No aisle seats available for disabled people who have to use the washroom frequently. No space for cabin baggage for disabled people who have to carry bulky medications or equipment to use on the flight. Baggage rules and fees are ridiculous. I have been an aeroplan member for 30 years and I fly frequently, but from now on I will choose offshore carriers. .

I would like to get my money back. I flight was 4 hours late on the way to detroit, And same on my way back to Brussels they cancelled my flight and give me an other ticket and i had to wait 5 hours.

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

My seat was one of those that couldn't recline, but the problem was that it was abnormally upright, so the headrest actually made the seat concave, which was uncomfortable and hard on my lower back. I had to ball my jacket up and use it as lumbar support. goodness I had it with me.

We had a long walk from one gate to the other. The busnessclass was full and we could not get seats together.
