Lucked out with extra legroom seat. Seat was broken though.

The whole customs process is a seemingly endless mess.

Good Movie Selection, food was descent, no screaming children,

Layover in Frankfurt too long; Unable to sleep on flight, nearby windows were open creating too much light, seating a bit too close to relax.

I left New Jersey during snow storm. Flights had been cancelled on the previous days but our flight was not. It did not leave on time, had to switch planes before we actually took off. My luggage was lost. I did not make my connecting flight. Had sty over in Panama. Got to my destination a day late without my carry on ( checked at the gate...lost). Still have not located my other 2 bags. Very stressful expirence. Will not fly united again. Staff at my lay over was poorly trained at handling the situation and my luggage issue is taking a very long time to correct.

Good service from crew. Fairly quick boarding process.

Aircraft seemed fairly new on inside, but didn't have power outlets. Small uncomfortable seats on a long flight that is almost always full.

Terrible customer service both on the phone before the flight, but Especially from the gate agent. Wow she was really horrible.

The flight attendants on board were good! They helped get everything straight. Easily could have been handled by the incompetent gate agent. Wow.

Delta did a really good job as always. Cheaper, more comfortable, and a WAY better experience than Alaska Airlines.

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.
