Pros: The crew were excellent. The seat was not very comfortable - it had a very firm seat cushion. The flight time was about 5 hours so it was OK. I adjusted to the feel of the chair. We had seats next to an exit door so we had more leg room which was nice.

Cons: The seat was not very comfortable. The seat cushion was quite firm. I sat for 15 hours on a Qantas seat which was quite a bit more comfortable. There was no onboard entertainment unless you had a cell phone and could download the West Jet app. I was spoiled by my flight with Qantas from Vancouver to Sydney. They had touch screens on the backs of the seats so you could choose movies, radio, games, and flight info and the seats were much more comfortable.

Mediocre 2.6

Pros: That it got me where I needed to go.

Cons: The crew, the food, the tv capability, the amenities. Overall it was the worst international flight I have ever been on. They confiscated my unopened beer I purchased after security point. They had me assigned to a wrong seat, so I had to fight my way 20 rows up as people are filing into their seats. The hot towel to clean your hands was dry and cold. The roll was hard as a rock and cold. The crew was rude and unapproachable. It took almost 3 hours to get them to reset my tv and when she finally did it glitched the whole time I tried watching it. The croissant was literally cooked to the paper and had to rip apart Croissant to get the paper off. They didn't serve the cocktail as promised. It was a pretty poor performance on all levels, and if this survey truly means anything, I hope this gets remedied.

Excellent 10.0

Pros: Very kind associate working at the gate. She helped me obtain my seat assignment and was a pleasure to speak with. Her happiness was contagious (even at 6am!). She put me at ease.

Cons: The last travelers in boarding line (including myself) had to check their carry on luggage because “there was no more room in the overhead compartments”. However, while I was walking to my seat, I saw ample storage space as well as suitcases that were laying horizontally or flat and could easily have been adjusted to create even more space. Given that most people pack their most valuable items in their carry on bags (as well as anything fragile), I was a bit uneasy checking mine. The associate who helped check my bag on the tarmac was kind. I was grateful that my luggage had a hard shell case.

Okay 4.0

Cons: Food was terrible. Paid for first class, expected something better than coach. Our food choice was a ham sandwich, there were better choices but the crew took them for themselves so nothing left for the 1st class passengers. Similar situation on our eastbound flight the week earlier. I doubt if Delta knows or cares that this occurs. After paying more than twice the coach fare, we expect something better than a ham sandwich on a coast to coast flight.

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,
