The staff on the flight was awesome, very helpful and kind to my friend who is terrified to fly. We were even ahead of schedule.

To pay for a carry on item is just crazy to me... not to mention you have to pay for beverages and snacks. All you are given is water.

Website would not let me check in the day before or the morning or my flight. There was an error every time and I almost got to the end once. I could not change the time of my transportation and arrived 10 minutes past the check in deadline (an hour prior to the flight taking off). I was refused access to the flight and offered a flight 5 hours later. The staff was rude and not helpful. I had heard negative things about Frontier and now I know why.

The aircraft was extremely cold throughout the duration of the flight. Of all of the long haul airlines I've flown with, I find that American Airlines offers the least leg room.

Plane was old and dirty, seat pocket had junk in it. Seat was broken and couldn’t stay up. In flight movies were from few years back with a center tv and no head rest screen. Crew on overseas flights tend to be older in age and less tolerant..much better on continental on the same route.

Seat pitch on the plane unbelievably cramped. When seats are so close that if you drop something on the floor you have to be a contortionist to get it, you know it's a problem NEVER fly the 787-900 economy.

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,
