World-class service at a price, convenience of connections, still free seat resevation and decent luggage allowance, two suitcases, for all of which other carriers extort extra payments.

Little bit quicker tray collection after meal.

There was a female attendant who as soon as I got to my seat asked me to stop blocking the aisle. I found this very annoying because I'd only just stopped at my seat. I found her manner disrespectful.

Transfer desk in Istanbul is terrible. Poor customer service. It took 6 hours to get transferred from the airport to the hotel.

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.
