It was a very small plane and was ok. No food or entertainment so there should be an option for NA.

It was a very small plane and was ok. No food or entertainment so there should be an option for NA.

I travelled in Business class for the first time and wish I could do that again.

The crew from Toronto Santiago (and the other way) weren't nice people. They seemed angry. Other flights with Air Canada had much nicer crews. Bathrooms always had sticky floors. Yuck!

No entertainment system. Paid extra for wider seats but not worth the cost. Flight left a little late and arrived early.

We boarded and then deboarded the plane after being told it needed something done that couldn't be fixed. Sent notice about 3h flight delay, then they clawed it back and we were 1h delayed. Very poor communication.

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

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

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