Heavy Hispanic woman got ill and I was really worried she might pass away because she kept laying forward asleep or passed out on the back of the seat in front of her. Finally they found a doctor who was bilingual and he took great care of her. So bravo for that UA!

Food quality was poor changed to smaller plane st last minute and had to get seats reassigned, no gin on the plane. Flight was delayed , your website was slow and could not do check in over the web, when I️ got to the counter 3 hours before my flight I️ was still delayed because I️ couldn’t do an online check in. Made it to the gate with one hour to spare but don’t think you should penalize people because of your own issues

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
