Nothing

We were delayed. Crew was rude. Then we flew to another airport just to get fuel, which further delayed us. We arrived late to the connecting airport and missed our connecting flight home. Not given food vouchers. Had to pay for 1 checked bag despite flying internationally. Overall, very dissasatisfied with Alaska Airlines and I will be sure to go out of my way not to book again with Alaska.

Flight was late and crew was very rude about it. Not to mention the flight times kept incorrectly updating and I almost missed my flight even though I was 4 hours early to the gate. Worst experience flying that I have had.

Hospitality of the crew.

My luggage that was to be loaded in the cargo area of the plane never was put on the plane. No clothes, no shoes, no medications, no gps radio equiptment, and no special fishing equiptment, (as I was on a sportfishing vacation). Really, Really dissappointed.

Last row seats don't recline. Unfortunate while on a red eye flight. There is no entertainment. Flight attendants could learn to juggle or do some magic tricks. Tell jokes maybe?

The crew was helpful and friendly, my flight was inexpensive

The seats were incredibly uncomfortable! Also, many people did not understand how to turn off the televisions, so it was pretty distracting to have so many monitors going when we all trying to sleep.

That it got me to Paris safe

No outlets to charge your phone, and the tv played the same movie over and over. The meals were also cheap. Didn't like any of them. Should have flown southwest or delta.

I like the efficiency and speed of the process.

Myself and another person were assigned the same seat. It was resolved.

I was told repeatedly I was in the wrong seat and told to show my boarding pass because I did not appear to the stewardess to belong in first class. No other passenger in first class was treated this way. It was rude and embarrassing, and frankly very unprofessional.

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.
