I waiting for 2 hrs to retrieve my luggage. Didn't get home till 3am.

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Flight attendant told passenger to move my bag in order to accommodate his not allowed roller bag then proceeded to crush my bag. When I complained flight attendant said roller bags take priority. Yet this flight was on Rouge which only allows one personal carry on. But not enforced. So I was penalized for paying to check my roller bag.

My flights were all either late or canceled. It was stressful and a waste of my time. This is the third flight in a row with Air Canada that has been a scheduling mess. Not appreciated.

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.

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.
