The seats were very comfortable with a fresh package of pillow/blanket and earphones waiting for us. A free meal, and snack. The take-off and landing were timely.

The bathroom was the worst I have ever seen. Old urine splattered on the seat (it had to have been left uncleaned from an earlier flight). There was no soap, The floor as still wet from urine and tp was still there. I was disguisted. Also there were only one bathroom in the back of the plane, which must have been a way to get more available seats. If other airplanes take that tactic, I'll stop flying altogether.

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. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
