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!

Staff was friendly

United has a system glitch and we were delayed. I got in around 1 am instead of 11 pm. I decide to order a glass of wine and since they don’t give receipts. I found out i was charged for 2 glasses instead of one. To top it off the co-worker i was traveling with didn’t get charged due to the inconvenience and delay. i travel a lot with United (higher status than him) and would have liked that offer (and not get charged one i didn’t order) being a mileage plus and credit card holder. I did go on line and ask for a credit and they did make it right and give me a credit.

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.
