Considerate flight attendants. Turned lights down for evening flight, so we could get some rest.

Flight was not on time. Time was changed a day prior with no reason explained. No in flight entertainment on this flight.

Not a single part has a positive remark

Well - this partner of westjet was terrible. The amount of re direction to get to the final terminal was absurd .. that's just my venting My real problem is that then "crew" or team that represent s the American Airlines / compass part was just useless. A hand full of people - myself included didn't get a chance to board the plane as they didn't make any announcements. Beyond disappointing. When you check in they take your cell phone "in case " well no call no txt no nothing. It was a joke the level of service No apologies or anything just a group of any tired patrons getting the worst customer experience. I'll never EVER book a flight that has anything to do with American Airlines or its partners

Delta never used to be my first choice in airlines, but of my recent experience with them has been excellent. The people from the counter to the plane have been professional and courteous. This is why I will fly with them more frequently.

I asked for a change of seat at the gate and was given it. It really made a difference to be at the window.

I had to change my return ticket early because of an emergency and Air Canada charged me $481.00 whenI only paid $371.00 fora round trip. How is that possible?

Compared to the flight going the other way, this one was much more comfortable. I didn't have someone's seat back in my face the whole time, and was able to enjoy games on my own device. I like that both USB and normal power options were available, so I was able to play games and charge my phone so I could use it after landing. The food was passable as well, which was surprising.

It's unavoidable when flying between multi-lingual locations, but having movies and stuff pause three times for each announcement gets annoying. The rolls served with the meals were very dry. These are small nits, and the flight was generally enjoyable.

Prices are per person, are for e–tickets and include all taxes & fees in CAD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
