I dispatched a guitar in a hard case. It was labeled fragile and sent to a separate compartment. The guitar was poorly treated and the case was broken all over. Very disappointing. On top of that I had requested window seat and got the middle seat. No food was served and there was no movies to watch or anything, considering this was a five hour flight

Friendly staff, quick to get on the plane after a long wait in the security line. TSA is very inefficient in SAN.

The cabin crew didn’t let us know we got free drinks on the premium seating area. Hey should invite us proactively to order our drinks. The menu does not contain info on what is included on the premium seating purchased. The seats are too narrow.

United's flight was delayed by 6 hours, couldn't make the connecting flight from Washington DC to Denver so they routed me to san francisco, spend the night at the airport there and then travel to Denver in the morning. Fortunately there was a very helpful crew in Schiphol that was able to get us on a flight with american airlines to philadelphia and then on to Denver.

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.
