We were sitting in first class. My husband went to use the restroom in our cabin and the female flight attendant told him to go back behind the curtain and use the bathroom assigned to his cabinet. He is Colombian and she surely profiled him, as I saw two other passengers from coach use the first class bathroom with no concerns.

There was a huge line for security but a sign telling us to expect a 15/20 minute wait made it more acceptable. The boarding to the Alaska flight itself was seemless and the on board staff were very friendly and helped stow my bag. The captain apologized for the late departure of only 30 minutes and kept us informed of how the flight was progressing.

Flight was delayed more than 5 hours. My all schedule had to be changed. I had to wait at Newark airport for 6 hours with my two little children. I want denied board compensation. Alaska has to fix it. I am very upset about this flight.

My entire family was upgraded into better seats. For my two kids, they were moved into economy plus. My wife and I were upgraded to first class. I did not ask for the upgrade, nor was I charged for the upgrade. So as you can imagine we were all very pleased. Even our bag's were properly managed upon our arrival.

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.
