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.

What’s not to like about this airline? Honestly, I am such a fan of their Airlines that it’s hard to imagine flying any other in the United States.

This was the first time flying for my granddaughter. She is 16 and was a little apprehensive to fly. The pilot & crew were very kind and welcoming. They provided a peaceful setting with their warm smiles & welcoming greetings. She commented about being greeted as she boarded the plane & being thanked as we said our good-byes. This was a trip she'll always remember. Thank you, Alaska Airlines!

Absolutely nothing!

Boarding and expected part of the flight were fine.

Because if weather, were were placed into a holding pattern, then rerouted to Ontario, where we were refueled and then flown back to San Diego. Very little information was passed along. The crew began to get short and frustrated with the passengers.

Fortunately as a passenger the economy flight area was very spacious due to low numbers of passengers. Which provided a comfortable seating space.

The entertainment could and been a little more variable in the film range provided. But generally overall I had a excellent flight. Food was good. Crew were very good and I would definitely consider flying United on my next visit out and recommend that my family did. Thank you United.

The flight, comfort, crew and entertainment was good on my flight

My luggage didn't make my connection so it was put on the first flight from PDX to SAN in the morning. The bag was scanned as arriving in San Diego, but it is lost and they think it's permanent. I had all my favorite things in my bag (it was a 10 day trip) and now I have to account for all of them, submit a claim and hope I'm reimbursed. It was a horrible end to an otherwise great vacation :(

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.
