The entertainment system was nice, the drinks were good, and the food was OK in Economy Class

The cabin crew was not very outgoing and not proactive in any way when it came to helping customers. The overall 777 plane was OK. I would have liked to see if the A380 was nicer. The entertainment screens were lower resolution with a good, but not great selection of content.

flight attendants from Nairobi to Istanbul were rude and unaccomodating. asking for a glass of water appeared to overwhelm the flight attendant.

The food was great. The seats were soft and there was enough legroom.

We were stuck on an aisle where the seats don't adjust on one of the flights, but it was a relatively short flight. The boarding process was a little disorganized, but we were able to get on the plane quickly. The worst part was the home airport. I don't know how much control Turkish airlines has over that airport, but the bathrooms we're absolutely disgusting.

The flight crew was great. Very pleasant and helpful.

They lost my luggage. Also the plane left Seoul almost an hour late. The plane itself was very old, so no electronic devices of any kind were allowed, some of the seat controls didnt work, and there were no private video screens. And this was in business class.

Nothing.

The flight was canceled but United and delta were still flying to New York. Air China was not working with them to help us. The earliest next flight was five days later...... their staff were extremely unprofessional. I asked to update to business class. One staff told me it was 1300usd, another one told me it was 3600usd, and one told me it was 10,000 usd???

Scored an awesome seat with no one next to me in a small cabin between first and coach class.

Even after I had carefully check luggage restrictions I got thoroughly hassled about my ski bag and had to pay considerably extra and do major persuading. The fact the air china desk doesn't open till within 3 hours of flight time at Tom Bradley international terminal at lax is madness. All these red eye flights going through security at once was one of my worst flight experiences. I the picture I took of it is an awesome representation of the term madness

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.
