Great staff/service on board. Check-in/boarding staff are very good, but overall supervision of their passenger intake processes needs attention.

Great staff/service on board. Check-in/boarding staff are very good, but overall supervision of their passenger intake processes needs attention.

Food wasn’t good but not their fault as I should have pre selected

The entertainment selection itself was ok but the screen couldn't be turned off which was annoying because I wanted to read and not be distubed by flashing lights in front of me. I could see other people having the same problem with their screens. The crew seemed to be too busy to be bothered by our questions/requests. I found the seat quite uncomfortable, especially for a long flight. As a short person, I've accepted the inconvenience of always having seats higher than comfortable, but my neck hurt after a while because the headrest was too high and couldn't be adjusted further. The seat pockets in this plane seemed to be faulty. I could see people near me having the same problem of everything falling on the floor because it kept detaching from the back of the seat. It was pretty useless to keep anything in it, even the menu and sick bag wouldn't stay in. The food was meh. The omellete was just a hunk of egg - my next flight leg also offered omellete but was so much better than this one.

PLEASE GIVRE US PERMISSION TO BOOK SEAT NUMBER EVEN WITH FEES

Chicago to Istanbul was a much better experience than I expected since I’m more accustomed to Qatar Airways business class. The business lounge in the Istanbul airport was amazing - loved the lockers and phone charging stations, and the bathroom was a spa experience in itself. The onward leg from Istanbul to Karachi was utterly disappointing. Terrible plane, and I felt like I was in economy - the seats don’t come near to lying flat and the food was mediocre. What a sad downgrade - it isn’t as though the ticket on that leg was cheaper. So, on that front, there’s no contest with Qatar airways.

Paying extra for premium seats was wasted. Turkish Airlines takes 2 seats for bassinet. The lady next to me had a baby with bassinet Bassinet was in front of my seat

Absolute worst airline. Charged us $720 to check 4 bags (2 of which were carry-on). Entertainment systems didnt work. And on a 12 hour flight they served 2 meals and never once came around outside of those 2 meals with a beverage or cup of water. Will never fly them again.

Food could have been hotter. More padding needed in economy seats

I will avoid this airline as much as possible. Service was rude, and I don’t think the crew knew how to answer a CALL LIGHT. I pushed my call light on the ohare to Istanbul and the Istanbul to Thailand flight because I was very very thirsty. NO ONE CAME. I pushed it twice! NO ONE CAME! Why have a call light when no one will come? My experience was the WORSE AND I WILL NEVER EVER FLY WITH THIS AIRLINE AGAIN. The cabin crew needs to learn MANNERS AND BE RETRAINED on their jobs on how to be helpful and kind instead of being short with their customers and ANSWER CALL LIGHTS! I honestly wouldn’t be suprised this airline goes out of business.

My flight from Washington, DC to Istanbul was close to excellent. However, my Turkish flight from Istanbul to Johannesburg South Africa was outrageously horrible. The flight was delayed three times and we did not get proper notification of the delays. We then missed our connecting flight in Johannesburg and right now we are struggling to get reimbursement for the overnight hotel cost that we had to then incur in Johannesburg and the new flight tickets that we had to purchase as a result of delays
