Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

Very bad experience with turkish airline tk 0001. Very uncomfortable seats and food ran out and crew was not helpful

The worst experience I have ever been in, they canceled my ticket the very last minute although it was Booked since October! They claimed it was not possible to change the schedule till January 11, 2026 and all my plans were screwed! My wife paid cash upfront a down payment for a surgery she was going to perform on dec 27th, and all these money lost! I’m considering seriously to get support

We were charged for checking in our bags! One bag per person was supposed to have been included in the ticket price, and yet Turkish Airlines charged us nearly $200 per bag!

Loved the food. No wheelchair was provided in Sofia even though wheelchair assistance was confirmed by Turkish Airlines

it was like a banya -so hot... They did provide a great experience with special food. one toilet broke midflight In general it was a peaceful and relaxing flight - for business class it was good.

I already checked in online and provided with a window seat by default which was OK with me. When I printed the pass at the airport, I found that the seat number was different (aisle but in same row). By that time, all window seats were taken up, I am surprised that TK can unilaterally change seats after completed online checkin.

I had ordered gluten free vegetarian but I got chicken instead. I wasn’t able to eat the meal. It’s hard not having food to eat when it’s an international flight. I don’t want to complain but when it’s a 14 hours flight. It would be nice to have something to eat.

Very bad this airline changes my schedule date of travel and get me stranded in Istanbul for three days, paid for only one day hotel accommodation with only one breakfast and i had to pay for lunches ,and dinners and hotel accommodations for the two and half days

Bad confort, bad seat take advantage of the political conflict to double the price
