Excellent customer service, from the check in process, to boarding, to flying 21 hours from Boston to Phuket with infant- we couldn’t have asked for a better experience! Everyone was so accommodating and helpful as we traveled with our 7 month old a lot g distance.

Passengers in front of you slamming their seats back that crushed and spilled my food all over me. Happened 3 times!!!

Stellar crew -- super friendly, served water/juices constantly, polite, attentive. To be commended Great choice of movies and entertainment but no wifi???

This was an older 777 -- no wifi -- pretty surprising on such a key flight at DOH-JFK! This is not the airline's fault but I had a crazy lady next to me who was very disoriented, who could not speak English and needed assistance. No one would deal with her! She had a little pouch with her name on it -- like a UM -- so someone knew something was not right when they put her on the flight. I bought drinks inside the terminal for this 14 hour flight but they were all confiscated at the additional security at the gate!! WTF

Good 6.0

Very nice staff.

Lack of diversity with the area crew. It would be good to have some Black area crew staff.

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.
