Was notified on a timely manner of any changes, if any, of the flight schedules.

My seat was covered in vomit and I will be reaching out to Air Canada

We were happy with the service and cost of checking a bag

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

This flight with a lot empty place , and I have more room, feeling comfortable.

It's kindof ridiculous that your system is even asking me about this since my flight was canceled and I wasn't rescheduled.

Flight was cancelled. Not enough agents to deal with the people in the line. We left and found our own way to Vancouver.

Flight was good, breakfast could be much better. We had come from a domestic flight on the same aircraft and the domestic flight was much better regarding service compared to this international flight.

Flight was great. Meal was really good. Boarding was terrible. Too many people in a small boarding lounge, zones not clearly marked.

3 hr delay at the gate while they were doing maintenance. Next time, do not board passengers while maintenance is being performed
