No charger and no entertainment on the way back. The plane's super old-like 80s old-with zero TVs. At least the free Wi-Fi works, so definitely bring your iPad. Also, no meal on this 7-hour flight.

No charger and no entertainment on the way back. The plane's super old-like 80s old-with zero TVs. At least the free Wi-Fi works, so definitely bring your iPad. Also, no meal on this 7-hour flight.

Meal and drink service was good. Old plane with old business class seats were quite disappointing

Flight and attendance were very good we had 2 hour delay that took the shine of it

The seat design in the premium economy section leaves virtually no room under the seat to store a bag or purse. Other than that, it was a great flight. Arrived early.

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

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

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

Horrible, we were on a little DeHaviland 400 that was really small and shaky. I am 5' 4" and I had to duck my head to get in it felt like an old war plane.

It might have been closer to being on time. Maybe next time I could fly from London to Toronto?

Air Canada canceled my flight last minute and I gave me next’s day night time my flight. No accommodations at all. I have a function on Xmas eve. So I had to took rental car last minute.i never ever book a ticket with Canadian airlines at all.
