I'd definitely take Turkish Airlines again, and maybe even arrange for a longer layover to be able to see Istanbul."

Cons: "Nothing! Everything was great"

Pros: "Nothing whatsoever."
Cons: "Worst customer expireince ever. I was making a short trip to visit my very sick mother. Turkish Airline changed my connection time without notifying me such that I had 5 min left for my cooection in stambul. They gave me no other option and blamed this on Kayak and kayak blamed it on the Airline leaving me with no options. I had to stay in Birlin at my own expense. Complaint filed with Turkish airline resulted in nothing. I made several calls for update and only repose I got was we will send an email to the complaint dept. and you will here in 24 hours. This has been going on for over 5 days with no contect, update or resolution. Once back in the US, I plane to file a formal complaint with FAA and more. DO NOT take this airline. They are worst airline I have ever used and will never use it again."

Cons: "Nothing to dislike!"

Cabin service included Turkish delight, hot towel, an amenities bag, hot dinner, hot breakfast, and snacks available thought the flight in the galley. Entertainment was on demand and included a wide selection. Seats were comfortable with reasonable distance between rows for coach (better than on many U.S. carriers). They have ample restrooms and they are split throughout the coach cabin, which made lines for the restroom almost nonexistent. Restroom amenities include hand lotion and refreshing spray - very nice."

Pros: "The service was very respectful and friendly."

Cons: "My seat did not recline and was broken. I was not happy about this as it was a 10 hour flight, and could not get comfortable"

Pros: "FOOD,, CREW ATTITUDE & TIMEING."
Cons: "AS BOVE"

Pros: "New, clean, and outstanding seat layout gives lots of room. Flew a 777. Crew was very friendly and efficient. This is more roomy than any U.S. or British 747 I used to fly.

We stood in a line for more than an hour because of this incorrect information. Additionally, the passengers were forced to stand in cold, windy rain because bus shuttle service and boarding was inefficient. Business class ticket holders were afforded no advantage while checking in either."

Cons: "No leg space Not a lot of TV shows"

Cons: "When I arrived at my final destination, Barcelona. Turkish did not have my luggage. I was convinced that they had lost it or somebody stole it. A day later they texted me and told me that they had my luggage and delivered it. I would have loved to gotten it without delay but I did get my luggage back so that's super nice!"

Pros: "Comfortable seats, nice crew...i forgot to reserve my vegetariano meal, but the crew provided for me.."

Pros: "Very good service, food, equipment and timeliness"
