Loved my first time flying on Bangkok Airways. The crew was handsome and beautifully groomed in their uniforms. Service and food was great. Leg room and comfort was good. Pilots were great, supported by the mechanics, air traffic controllers, etc. Very positive experience. Carol

Seriously, they not only allow just 5kg per person for handluggage which in itself is a joke, they also do not allow that two parties traveling together bring one handluggage weighing 10kg? Why? Nobody knows. Total and complete failure for such an expensive airline.

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.
