I did like the food, very nice stuff.

I order some to help to find my gate for a another international flight,but no one came. For such long flight, definitely need to have sits with more space. Very hard to flight in such tight space

The flight itself was very nice quality again. Crew was very friendly, priority boarding for international business. pod seating was super comfortable.

No alcohol beverage service before take off. One of the only airlines that does this. Also flight was delayed again in Istanbul. We were delayed on our layover in, and out of Istanbul. Both times stuck on the tarmac. I see this as a common problem

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,
