Flight wasn’t bad for what I paid for. One MUST definitely do his/her homework before flying to be prepared for all of the extra costs, etc... I was glad I did and was prepared with my own food, neck pillow, etc. I didn’t expect much in terms of creature comforts and therefore wasn’t disappointed. There isn’t much space in the cabin, so I was glad to have my 6-year old in between us 2 adults. Crew was pleasant r and professional. Ticket agent was helpful if a bit “assertive”. I probably won’t try to book them for long flights, but for short flights their fine

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.
