Turkish Airlines was great. My new layover was over 18 hours due to inclement weather back home in Washington DC and the airlines provided me with a hotel room and dinner voucher during my layover

Bad sitting every flight not good experience with food either

My, Syed Zawar Hussein Shirazi frequently flyer membership number was not included on my boarding pass from O’Hare to Istanbul despite my reminder to the attendant at check in. Further she forgot to give me my boarding pass form Istanbul to Lahore and she needs to improve her customer service, please 🙏

Everything about that day was great I was happy with how things went as a first time traveling with the airline thank you for all that you’ve doing by taking us there to our various destinations thanks.

The seats were extremely small. Boarding was not communicated correctly. It wasn’t a pleasant trip.

I am always amazed with the great service they offer on their regional and international flights

Nothing luxury about Turkish airline compared to many other airlines

Entertainment was good. Flight was delayed, nearly missed my connecting flight. The gate was changed on several occasions. My luggage did not arrive on time and had to leave without it.

Service was slow and checked bag was off last evening when flying business

Everything was good except that they didn’t give us seat for our connecting flight in Istanbul from Cairo. This created a panic situation. Hopefully they give all customers connecting flights seats right from the start.
