Easy boarding and finding seat; good food and liked that wine was available, good movies to choose from

Seat was not comfortable, I am 5'1" and the head rest was too high, fortunately I had my own foam neck support. Bathrooms could use more cleaning during flight as one was grossly covered with urine right after turbulence was experienced. One crew member appeared to be having a bad day and seemed unhappy to be at work and was impatient with all.

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.
