Business Class pods are horrible. If you're petite, you might be able to sleep on the uncomfortable seat and bed. Crew and food are fantastic.

Business Class pods are horrible. If you're petite, you might be able to sleep on the uncomfortable seat and bed. Crew and food are fantastic.

This flight was in the air when the national power outage happened on 28 April 2025 in Spain and Portugal. As a result Lisbon airport was closed and the flight was diverted to Porto. There were no phones, internet or ATMs working and the Turkish Airlines ground crew in Porto were trying to find alternative transport to Lisbon (by bus). This did not materialise until late in the evening. The Turkish Airlines ground crew suggested that passengers may find their own way of getting to Lisbon. That in itself is a failure of Turkish Airlines, but understandable as there were no means of communication. The Turkish Airlines ground crew also said that any expenses insured for travel to Lisbon will be refunded by the Airline through their website. Unfortunately, I could find no way to travel back to Lisbon other than to hitch hike with an Uber driver. Because no systems were available and no credit card payment possible I paid the driver 140 Euros in cash with no receipt as systems were down. I arrived at my Lisbon hotel at 23:30 (flight was scheduled to land at 12:30). Upon contacting Turkish Airlines for compensation they are not willing to do anything as I do not have an invoice for my expenses. They do not even consider the 10 hours of delay and inactivity on their part as a reason to provide any sort of curtesy towards me. I find their behaviour appalling.

Pretty standard for long haul international flying. Food was fine, tv/movie selection was great, wifi did not work at all, crew was pleasant enough.

My experience with Turkish Airlines was highly unsatisfactory. I was prevented from boarding my flight from Istanbul to Miami because they closed the gate 30 minutes before departure, despite my timely arrival. This inflexible rule forced me to book an alternative flight to Atlanta for $1,342.92, as there were no available flights to Miami. Upon reaching Atlanta, I had to book another flight with Southwest Airlines for $270.98 since there were no connections to Miami. Altogether, I spent $1,613.90 on additional flights. Consequently, my total travel time extended to 35.5 hours. The overbooked flight and the enforcement of such unreasonable rules enabled Turkish Airlines to exclude passengers without providing compensation, thereby compelling them to buy new tickets to reach their destinations. This practice is unacceptable, and I intend to report it to the Better Business Bureau and the relevant regulatory authorities.

On this route the plane was also late and I almost missed a connecting flight to Tashkent. Moreover, my bag did not arrive with the same plane and only on the next flight from Istanbul. I was supposed to travel further from Tashkent to Astana and Saudi Arabia and if I didn't collect my bag in Tashkent I would have missed the next flights because I couldn't travel without my bag and all valuables inside it.

Turkish airline always good Only Turkish representatives at the gave need to be more helpfull to any staff who traveling on Turkish airline . One situation happened Ist to jfk on Feb 29 TK3 had seats I asked them to transfer me to tk3 because Feb 29 tk1 was oversold and they advise me that I might not make it for tk1 I asked them to transfer me to tk3 and they say no they can’t do it I been telling them you know that I don’t have a chance for tk 1 why would you let plane go with some empty seats on tk3 if you can transfer me to tk3 and have less staff on tk1 and still told me no I waited for tk1 9 hours and only last minute I got seat on tk1 It was not easy situation but I am glad I made it home Thank you Turkish Airline One more suggestion for Turkish Airline you need to make a FIRST CLASS cabin it would be so cool 🆒 Good luck all the best See you more

Service for wheelchair person is very poor. No display at exit door from Delhi to Istanbul airport, so you cannot decide where to go, and the helper for wheelchair person asked $10.00 american money, when I said you should not charge or I asked him to take indian money. He said he needs only American dollars and bring me back and dropped me at the same exit door helplessly. I felt bad very much but was helpless. And ranaway. I was to take his picture to post it on the website. So many passengers were waiting for the help, ultimately one buggy came and helped the passengers and the driver did not ask any money. Please let the air authorites know the incident.

Vol Paris Istanbul en retard. Baggage en soute mis sur autre vol car seulement 15 pour attraper le vol. Baggage livré en soirée le jour d'arrivée.

The lines to check in both at LAX and coming home from Cairo were ridiculous. Close to 2 hr to check in. I had pre-checked at LAX so I was able to get into a shorter line but it was still over 45 minute wait. In Cairo the travel agent with us was able to get us in the Business Class line but that was over an hour wait. Then in Cairo the plane was delayed over an hour. Missed the connecting flight. The airline gave us a food voucher for a few US chain fast food restaurants and the items that could be ordered we limited to only 2. Had to wait 4-5hrs for the next flight. I get that flights get delayed and its not really anyone's "fault" but the airline has an opportunity to demonstrate that they realize that this is a real inconvenience and step it up a bit.

There were delays in take off. It could be due to airport management, not due to Turkish Airlines management though.

The entertainment screens need to be updated. Very difficult to navigate through with old equipment.

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!

Terrible experience. I was stuck in Germany for two full day because your flights can't leave on time. You guys suck!!!

When I got to the airport, the airline lost my reservation and couldn't give me a boarding pass. I had to sit with the travel center for an hour until they could figure out what was going on. I thought I was going to miss my flight.

Poor communication from airline, didn't start boarding until 15 minutes after we were supposed to be in the air and there was no communication from anyone about a delay except the screens showing we were "on-time" and already "boarding" which finally updated 5 minutes after we were supposed to be in the air to "delayed".

Prompt boarding, safe landing and they didn't lose our luggage. No entertainment and no USB plugs to charge phones. No food, though I might have been asleep.

I was served cheese that had mold on it. I brought this to the flight attendants attention and she informed her supervisor. They were apologetic and offered me a replacement, but I think that is extremely insufficient compensation given I ate bad cheese causing food poisoning for my birthday vacation. Both me and the flight attendants photographed the cheese, and I was told they’ll “put in a ticket” to ensure it doesn’t happen to someone else…….

Seating was so poor, once the person in front of you recline their seat, they are in your face. Leg room was terrible, and I am 5foot 8inch person. Dinner was so fool of fat, chicken thigh was in one peace, hard to cut in that small tray. This is my second time traveling on the same flight from Denver to Munich, and I received same bad food, and the seat discomfort. Lufthansa was no longer the company what it once was. I am flying 25 years, and it's only worse than before. Fly crew was at times rough, bathrooms are smaller and dirty, no refill of the soap....missing toilet paper....Disappointed

They cancelled my flight day before without any support to rebook.

Plane was very delayed. US agents unhelpful in connection flt and in seating. No real info given on delay.
