I would like to review the next flight from Toronto to Fort Myers as it was a disaster!!

I’m a thin guy, but my hips were plastered on either side of the chair. These chairs are so unbelievably small now. It’s miserable flying in them for anything longer than an hour

It was just fine. I managed to make all my connection too sbut had trouble in Munich with no wheel chair and trouble trying to get help from the airport people to get to the other terminal for my flight. Finally a wonderful lady Amelia, helped me to make my flight connection Timon with zero time to spare.

Boarding was slow due to airport security. The flight, staff, service and comfort were excellent. A little more complementary meals for 4 hours + flight will go a long way.

Awful. No running water on the plane. Bathroom extremely grimy, panels taped into place. Breakfast eggs with a terrible texture.

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

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. .
