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

Digital check in is very poor with air canada compaired to other airlines

Flight was delayed 3 times. My luggage was sent to Saskatoon instead of Casablanca - airline got it sorted out in two days. Received $45 in meal vouchers to use in the airport.

Seats were so small. I’m 6ft and a good 20% of me hung out into the aisle and the flight attendants come dashing with the cart. On multiple occasions they hit me before saying mind your elbows and knees. I’m like, yes, but where do i put them. There isn’t a space that exists that i can fold into. The carts are so close to the seats when they pass through that i regularly felt water dripping on me as they poured drinks. Overall 3/10 experience. Highly unlikely to recommend

Baggage delayed we had to catch our cruise without any clothes 😒

Air Canada Rouge is great. Toronto Airport is the usual nightmare
