Got home 30 min earlier than anticipated. A welcome result when you're tired from a long day of travel. Customs and bags were quick and we were home in no time.

Got home 30 min earlier than anticipated. A welcome result when you're tired from a long day of travel. Customs and bags were quick and we were home in no time.

Not sure what happened, but for some reason we had to sit on the plane for an extra 10 minutes once we arrived in Abbotsford. Obviously, it was an engine issue.

The gate personnel and flight attendants were all friendly and diligent. The poor attendants from London to Calgary were 2 colleagues short, as one of their team broke her leg on the way to work, and the other stayed with the invited colleague. I felt bad for the crew, but they did a great job regardless.

We were delayed by an hour without any commu8nocation about what was happening. Long lines just hoping to hear how long the wait would be.

8 hrs. Of waiting instead of couple of hours..the only good thing I'm still able to go to my destination...

Flight delayed missed connecting flight crew not very helpful very frustrating customer service

Our biggest complaint was a major schedule change that was not communicated to us in any way. Luckily the time change went later not earlier so we did not miss the flight. Our email addresses and phone numbers were on file but we received no email no text message no nothing. Short flight so not much to say.

The personal item sizer cannot take a standard backpack, and the cabin luggage sizer cannot take a standard carry-on. Designed for people from the island of Lilliput!!. and also compels people to pay additional fees to check their bags. Making money by ticking off the passengers is a very short-sighted business strategy, especially since they have a choice of carriers

The plug in to charge our phones are all loose my block would not stay in!!

My flight was cancelled due to weather but Westjet got me on a new flight in a timely and efficient manor.

Delayed over 1 hour boarding and on tarmac for no apparent reason. Boarding was awful. Extremely late. No employee knew what they were doing. Loading zones out if order (zone 2 before zone 1).

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

Excellent. I could change my flight and cone back a day earlier. Everything was great thanks 😊

5 hour additional delay in vancouver with 3 kids and all the compensation was a meal voucher of 15 each, which goes nowhere in an airport. This delay resulted in us needing an additional hotel night in Calgary at the cost of almost 300 dollars

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

I wish they gave the earphones earlier rather than when we are already in flight.

Very nice staff members are very nice and friendly helpful

We were a little late pushing back ,but arrived a head of time.

The crew were fabulous. The flight was bumpy and I always like the captain to tell me what that is about or my imagination gets carries away.

W ended up getting stuck in Edinburgh Scotland during the air strike. They cancelled our flight and No help to get us rebooked. All said down that cost us over $2,000 extra at least to get home. Hopefully we will be reimbursed somehow! Won’t be flying Air Canada again
