Mediocre 3.0

Cons: Late departure, late arrival, stuck half an hour on the ground before being able to get out of the plane while the PA blasts a message about Alaska being the most ponctual airline : a joke

Excellent 10.0

Pros: I used the call button for the first time because I had ignored the drink service and desperately needed coffee. The flight attendant came back with a smile and got me some of the best coffee I could've asked for.

OK 5.3

Pros: The airplanes were nice, clean and comfortable,

Cons: The food was nasty! The choices were aweful, the crew didn't look profesional!! They look like they were going to sport event.

SEA
SFO
OK 5.3

Pros: The crew was courteous and professional.

Cons: The seats were too close together. For someone that is tall, the airline standard that is followed is inadequate without paying an up-charge.

OK 5.3

Cons: Start serving people early and the plane smell musky

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.

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.
