Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

Delay, after delay, after delay. It was hard as an adult travelling alone. I felt bad for the families with young children to entertain for several hours. Agents and crew performed to their usual good standard. Air Canada, never again.

I liked the flight but the check in was horrendous. I have booked with you before but not ever had to pay extra for luggage, it was not clear on booking, I didn't know there was different categories of economy that meant different allowances. So was alarmed when we had to pay a further £120 at the check-in at a point of not changing.

Delayed over 1 hour boarding and on tarmac for no apparent reason. Boarding was awful. Extremely late. No employee knew what they were doing. Loading zones out if order (zone 2 before zone 1).

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
