When our flight was delayed in Denver the agent at the check in gate worked very hard to get our flight plans changed with as little impact as possible.

We understand that delays happen but due to a delay on American Airlines we have lost our luggage and it doesn't seem likely it will be returned. We had five pieces of luggage lost during our flight from the U.S. to Spain. When we arrived in Madrid we were told that all five pieces had been located. When we went to pick them up the next day there were only four pieces at the airport. We were told the fifth suitcase would be delivered when it was located. It's ten days later and there's no sign of the luggage. It has taken multiple phone calls to get the information about the luggage correct. They assure me that they have everything correctly documented and then when I call back they haven't changed a thing. It has been a very frustrating process overall.

Stuffy on the plane. This might not be the airline’s problem but it was hot and the air vent didn’t cool me down.

Delayed flights leading to incredibly tight connection times, staff inconsistent with messaging re the source of the delay, zero compassion for customers, offering $700-$1,400 to get off the plane when you charge $200 to change a flight 2 weeks in advance is especially galling! Will not fly with United again whenever there is a viable alternative to my destination.

The staff was courteous and efficient. The entertainment selections were diverse. The seating was adequate for a long haul flight.

The check-in process took 50 minutes at the counter as the staff told me that I needed a visa for China (transit) while that info was incorrect. I had to deal with online customer service while the person at the counter couldn’t help. It finally took 3 people at the counter to send me away. Once on the plane for a 14+ hour flight, I couldn’t use the bathrooms freely as they were filthy. The staff obviously didn’t maintain the bathrooms during the entire flight. The food served made me wish that I had bought take-out food for 3-meals prior to my boarding. the quantity of food was inadequate for the long flight as well. 1 extra snack would have been appreciated. I will likely book my future trans-Pacific flights with another airline.

None of the experience was pleasant

First flight was delayed causing us to miss the 2nd flight and we ended sleeping on a chair at the airport waiting for a morning flight. AMERICAN AIRLINES didn't even have the decency to put us in a hotel for the night due to their delay. Then they added a 2nd lay over which was delayed for hours also. Traveling was to visit my mother who had cancer and I was sick so this made the trip even more distasteful.

We left Chicago close to 6 hours late and they didn't bother to put anyones luggage onboard. So we arrive close to 6 hours late and no luggage so we have to wait in line to fill out paperwork to have our luggage located/delivered along with everybody else who had checked baggage. That can not be a cost effective way to run your business

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.

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.
