The seats seems abit small and the reclining is too much, the seat in front of me came back too much and made it uncomfortable for me.

As a first time flyer with Turkish Airlines. My experience was very good due to the factor that there were to many passengers on the my first flight compared to my connecting flight. However, I know that nothing is perfect and all companies are trying to accommodate their passengers to the best way possible. I will always say, a FEW INCHES will go LONG WAY. That's something all airliners should consider, and not only the money aspect!!! A long time commitment is better than one time service! Thank you

Flight was delayed. While standing at the gate, a note appeared on the sign saying the gate had changed to a gate far away. No member of the Turkish airlines team got on the microphone to instruct passengers to go to the other gate, to ignore the chiron, etc. Finally, the message disappeared. Eventually, the flight began to board. Very slowly. More slowly than I experience with other airlines. Though Istanbul may just be slow . . . In all other ways, great flight, great entertainment (top notch movies), great service, excellent food, comfortable lie-flat seat, dimmed lights, etc.

Staff at the airport wasn't helpful or friendly. Probably the worst airport experience I have ever had, going and coming. The staff on the plane was better. Still not super friendly or personable. However, they were not rude like airport staff. They ran out of certain menu items. Maybe could have been prepared better? Overall just ok.

It was a pleasant experience. In flight entertainment could have been better

The desk crew at the LAX crew could do better. A girl named Mahesi was very abrasive and unfriendly. She needs a better customer service uproar.

It was peaceful excited We enjoyed it always Turkish peaceful excited

Istanbul to Lahore flight was less than standard for international business class cabins. Seat did not were not flat and it did not operate easily. I had to push buttons hard repeatedly to operate the seat. I was in 5A seat

IAH to Istanbul was outstanding across the board. The flight from Istanbul to Male was good, not great.

the cabin was kept too hot. couldn't sleep as a result

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

Terrible. Lost our luggage for 4 days. Did not advise passengers there was a strike in Barcelona Airport and had zero personnel on hand at airport to advise passengers on where to go to file claims. We had to fend for ourselves. No assistance at all other than an online claims submission process that we had to find out about on our own.

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

Everything could have been better. What needed to be wrong with United went wrong

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

Very good, i got two seats for myself, and was comfortable with the blanket i got

I hated the FRA Airport. Confusing signage, including the path to Immigration and Security It seems that the airport grew haphazardly over the years. I have been through multiple WW Hubs with much better experiences.

Economy Priority seats are extremely uncomfortable. There is no way to escape the boxed in feeling, particularely because the distance between to rows are too short, the hard edge of the front row is keeping legs confined. There is no elevated place to put your feet. I am of average, European size.

Terrible. Both flights were significantly delayed, no luggage, made me check my small bag when many, many others had much larger carry-ons, not even a bottle of water . . . I will not fly Discover Airlines again.

I was deceived on the Kayak site expecting a ticket, but instead finding a "standby" reservation. When I tried to change the ticket, I paid almost twice the price of the original ticket. Then, the airline refused to give me the reserved seat I had chosen and paid for. I think I deserve a refund for this leg of my trip because I was doubly charged and did not receive what I had paid for. I put in a complaint with Lufthansa because the ticket was sold originally sold as a flight they listed. Someone here needs to take responsibility.
