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

Air Canada cancelled our flight and reschedule it 26 hours later that completely interrupted my family's long waited Japan trip, it wasn't due to natural reason such as weather but under the company's control. On the day we wasted 9 hours of our time from 6am to 3pm, including a few hours in the customer counter waiting for supervisor to handle our rescheduling. When we came to the counter for rebooking help there were at least 4 employees on the counter but we were told they were not trained to handle customer rebooking, we were also told the supervisor could come 10:30 to handle our rebooking, but she showed up more than one hour later, the end result was exactly the same so the few hours we spent waiting for her was completely wasted; We already prepaid hotel and all the tickets for the our stay in Tokyo so all of the cost for the first day is completed wasted; The $80 meal voucher issues was far less than our financial loss due to the financial cancellation, and it was not surprisingly invalid (as Your company screw up everything possible along the flight), the vouchers were supposed to last 72 hours, when we tried to used it at our lounge next day less than 24 hours from its issuing at a designated restaurant, the worker there couldn't scan the vouchers after multiple tries on all 4 vouchers issued, so we had to pay the food from our own money; For the two return flights they were also full of unfortunate events that caused bad experience and further delay and waste of our time, both flights departed late and the last leg had another significant delay of more than half an hour after touchdown, the gate was for some reason not available so we waited more than half an hour, when we got out of plane it was almost one hour later than the supposed arrival time; The gate you arranged is the farthest in Vancouver airport, also was the luggage pickup location in Seattle airport; We also called customer service for rescheduling help and after a long time wait (more than an hour) we got a call back but the CS representative was equally clueless and unhelpful. Other than a fatal crash, your company couldn't do anything right and provided the worst service possible among the tons of flights we have taken in our lives.

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. .

taking our carryon and forcing us to check it through

Obviously the leg room...but I guess that's what business class would be ..expensive though.

I was very excited when we were to arrive 19 mins early . However that did not last long since there was no available gate and sat there waiting almost a hour.

Seats horribly uncomfortable. Air nozzles didn't work so very overheated.

Every person and every experience with Air Canada was excellent. All customer service was outstanding and done pleasantly. The notifications through their App were timely and informative. This airline shines. All other airlines should take training from them.

Better than usual. We’ve flown air Canada for years at least once or twice a year and used it to bring our Canadian American son back and forth from USA and Canada and Europe and we have had MANY bad experiences with late flights, missed connections, boarding issues, for almost 10 years. Just lots of bad experiences. This one wasn’t bad at all. It’s simply what we expected. Even though the first flight this time was 45 min late in leaving due to a maintenance issue, that didn’t mess us up. But all else was fine so we were pleased.

It was just ok, after a weather delay and had to take 3 planes in one day I asked for another cookie and she said no only one per passenger, found that a bit pity after spending my whole day in airports and planes
