Food not included with insane flight costs

Good 7.6

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.

Excellent 8.0

It was overall a good experience, cannot complain about the service as it was great.

The weather caused a bumpy return flight but that is not the airlines fault.

Excellent 8.4

One of the crewmembers (regrettably, I did not catch his name) was incredibly kind when I moved seats to accommodate a couple that wanted to sit together. He really made this flight great.

Seats were comfortable but the row I moved to did not allow me to recline.

Excellent 8.0

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.
