Pros: The crew was amazing and cheerful considering the 2 hour delay and that is was so early in the morning

Cons: The communication was non existent. We started to board then suddenly the crew shut the door and everyone disappeared for 2 hours. We were left wondering what was going on and there was no one to ask!!! No updates on the apps just that our flight was boarding at a time well past

Okay 5.2

Pros: The plane was timely and clean.

Cons: It’s suggested to arrive 2hours before your flight, however the check in desk wouldn’t allow anyone to check in and take luggage until 1 hour before the flight began boarding. Keep in mind we still needed to get through security. Was a little annoying but not to awful. The worst part was the seating

Pros: Alaska Air sets the standard. Seated in exit row. Power outlets at seat. 500 movies/TV shows available to stream on devices. Ok food available for purchase. Flight attendants seem knowledge and a cut-above service-wise.

Cons: Honestly in-flight food for purchase is just ok. Not great, not terrible. Just doesn't seem like they're trying that hard. Unusual for Alaska.

Cons: The terminal was under construction and extremely crowded. We could have used some help from the ground crew shepherding people, keeping hallways clear. Would probably be useful to not have gates immediately opposite each other both trying to board with space being so limited.

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,
