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.

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.

Turkish Airlines will be my first choice to fly in the future.

Flight Singapore - Istanbul was perfect. Flight Istanbul - Sao Paolo - Buenos Aires was really good but there was a big delay in Sao Paolo (Brazil) due to a problem with the ground staff and not related to Turkish Airline. Overall a very good and solid experience

I recently flew with Turkish Airlines, and I can confidently say it was one of the best travel experiences I’ve ever had. From the moment I boarded, the crew was incredibly attentive, warm, and professional. They went above and beyond to ensure everyone was comfortable and well taken care of throughout the flight. The highlight, however, was the food! I’ve flown with many airlines, but Turkish Airlines sets the bar incredibly high when it comes to in-flight dining. Every meal was fresh, flavorful, and beautifully presented. The variety of dishes, even on a long-haul flight, was impressive. It felt like dining at a high-end restaurant at 35,000 feet! The seats were comfortable, the entertainment options were great, and the overall atmosphere made the journey enjoyable. Turkish Airlines truly excels in combining luxury and hospitality. I wouldn’t hesitate to fly with them again—highly recommend!

The fully flat bed in business class on the 777 is a little narrow, and the 2-3-2 configuration is now dated, but otherwise a comfortable and pleasant flight. It’s hard to beat the value too.

My experience with Turkish Airlines was extremely disappointing. I was denied boarding for my flight from Istanbul to Miami because they closed the gate 30 minutes before departure, even though I was present and ready to board. This arbitrary rule forced me to book an alternative flight, not even to Miami but to Atlanta, costing me $1,342.92. Upon arrival in Atlanta, there were no connecting flights to Miami available through Turkish Airlines, so I had to purchase an additional ticket with Southwest Airlines for $270.98. In total, I had to spend $1,613.90 on new flights. As a result, my total travel time extended to 35.5 hours. The flight was overbooked, and implementing such arbitrary rules allows Turkish Airlines to exclude passengers without compensating them, compelling them to purchase new tickets to reach their destination. This practice is unacceptable, and I plan to report it to the Better Business Bureau and the appropriate regulatory authorities.

This time around, I felt that the crew wasn’t very professional. Speaking / laughing loudly and rushing through service.

I canceled this flight after turkish airlines did not provide any consideration for a death in the family while in Singapore

Istanbul to Miami Sector the plane was nice and clean except for no WiFi during the entire flight. The flight from Karachi to Istanbul was another story .The sad part is we paid for business class to be comfortable. The foot rest didn’t work. The flight attendant had to push the seat to put to recline position and/or put it back. This was not only for me but for other passengers in business class. The tray table would not come out so had to get help from the passenger sitting next to me. I understand that they may have to use old planes but Turkish Airlines have to make sure that the things are functional especially the duration of flight is six hours and they are charging a lot of money. It seemed that i was flying a domestic sector instead of an international flight.

I like Turkish Airlines Business Class to go to Europe, but it would be nice to avoid the back and forth to Istambul, and the very long layover. Regarding the 10 hrs. layover I have to say Turkish Airline lounges are superior and offer really good quality sustainable food… for ultimate comfort they also have great showers and suites to rest!
