Nothing !

Service was horrible. No leg room. Flight attendants were gossiping loudly behind me. Flight was late to leave and we were stuck at the gate once we landed.

Okay 5.3

Boarding was simple and efficient Seat was better than usual

Dinner was okay, the mid-flight snack was awful and made my wife sick, breakfast was better. Entertainment console crashed four times, first crew member didn’t seem to care (aloof for most of the flight), other attendants seemed marginally more interested. No one checked back to see if the problem was resolved. Flight attendants seem to be in “check the box” mode doing only what was necessary.

The crew could not have been better. I was really pleased with the movie selection. However, the food is really terrible. I got a dish that was chicken, mashed potatoes and green beans, which would have been acceptable had it not been covered in bbq sauce.

Absolutely nothing

Everything about the flight was awful. Food pathetic, my monitor didn’t work, smooshed between 2 overweight passengers. Flight crew lacked simple etiquette.

The fact that my original seats were not given. The other issue was that Alaska wasn’t my airline but American was. They didn’t even tell me until I got to the gate, moved over to another and then got transferred over to my gate.

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

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.
