If there was a less than one star that is what they deserve. SFO flight was late. They gave away my seat on my connection to Kalispell. They basically blamed me for being late and not being there on time. Two others from my flight were allowed to make the connection but told me that they gave my seat away because I was late. We all showed up at the same time from the late flight. I talked to 3 people including customer service and did not get a single “I’m Sorry”. Do they not communicate with each other when a flight is late and they have passengers for connections running late? They told me they don’t talk. The best they can do is put me standby for 9:30 flight and if I cannot get on that flight I have to wait until morning. My daughter is in a competition tomorrow morning and thanks to Alaska Airlines I’m going to miss it. I’m sitting here writing this review, paying for a dinner I should not be paying for and probably searching out a hotel room until morning when I can catch a flight. Unbelievable the lack of empathy.

During flight, the flight attendant would not fill my travel coffee mug with coffee. It seems about 50/50. Sometimes they fill it up, other times they do not. I wish it was more reliable, one way or the other.

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.
