Usually air Canada flights suck but this one wasn't bad. I was pleased that they had a vegetarian option available for everyone.

Flight was as good as I have come to expect from West Jet. Always my first choice.

The check in process was delayed as one name got changed from the Expedia booking to air Canada (last letter missing from William) so we could not self check in as the name did not match the passport. It was stated by staff "that happens all the time". Everything else was great.

Would be nice if Expedia were clearer about checked bag charges before booking.

Flight entertainment wasn't working all flight.

Delays were annoying but not the airlines fault

A free coffee would be great but they want you to pay 2:50 pounds. They are one of the few regular airlines that charge for coffee and water.

Uncomfortable economy seating, unhealthy food. Standard operation.

The poor staff on our flight had to deal with some shenanigans from other passengers switching seats, pretending they didn't speak English, disregarding safety instructions, choosing not to sit in their seats, not wanting to put their carryons under their seat or in the luggage compartments....and they dealt with it like champs! My husband and I were super impressed!
