Turkish Airlines apparently no longer gives you 2 checked bags allowance on international flights, so that pleasure cost me $165 for my second suitcase at the airport. On top of that, they damaged that very suitcase, which happens to be a designer one and part of a set - ripped one of the four wheels right off.

Turkish Airlines apparently no longer gives you 2 checked bags allowance on international flights, so that pleasure cost me $165 for my second suitcase at the airport. On top of that, they damaged that very suitcase, which happens to be a designer one and part of a set - ripped one of the four wheels right off.

Pretty standard for long haul international flying. Food was fine, tv/movie selection was great, wifi did not work at all, crew was pleasant enough.

Seats were in disrepair. Seat back pockets were all broken. Seats recline very far, which is comfortable for occupant, but confining for person behind.

Very poor service. Not friendly and special food ordered but not served

The flight and crew members was excellent. The food was nice too. Over all service and time is commendable.

Very bad from ISTACC leg of flight specifically the seats. These seats are for economy not for Business class. I suppose when flying to a third world country you can fly any craft and no one questions it. I was very disappointed for that leg of the flight. This needs to change.

The flight attendants were very attentive and recognized that I had a very short layover for my connecting flight. The head flight attendant went out of his way to find out my connecting gate and ensure that I expedited the aircraft quickly.

Plane was hot in our section of aircraft making it difficult to rest. We informed the staff but adjustments were not made. Seats were terribly uncomfortable- unlike the other long haul flights we have flown on Turkish Airlines. It seems both issues are due to plane being an older Airbus

Turkish airlines always is an excellent airline, bottle water, comfort kits were provided. Decent food on board, friendly staffs.

The food was disgusting that only what i wanted to say
