Pros: Better staff than normally, which was both surprising and pleasant. Flight made it on time for the changeover in Zurich, which is very important.

Cons: Extra charge for luggage - it showed up in the itinerary only after everything has been paid for. And even the paid suitcase allowed 23 kg only. It has been just over TEN years ago that you had two suitcases at 32 kg each included in price! Does the airline seriously believe that you can travel around the world with just a swim trunk in your pocket? This policy is an insult to any world traveller. We do not all go into an all-inclusive resort! The only drink offered during the flight was plain water, again a step down from before where they also offered others, e.g. orange juice. Seating - now that big persons have the right for two seats for the price of one, when will the same rational apply to tall people?

Cons: The entertainment system didn’t work well to start, and then stopped working altogether 2 hours into a 5hr flight. The staff tried to fix it and were very apologetic, which made up for it. The seats were a little too hard for me. I was pretty sore by the end of the trip.

Cons: To my shock, my boarding pass while scanning to enter the aircraft was rejected with wild flashing red lights saying my trip was cancelled.

Cons: Turkish Air keeps their planes unbearably hot. I’ve complained before and they always say it’s “Normal” for the industry. I fly over 1000,000 a year and I’m telling you it’s not. Also, I bought an “Extra” room seat and the seat is still ridiculously small for anyone over 6 feet.

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.
