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

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

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.

Terrible. Delayed. No one would help. Just limped about like a piece of meat

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

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.

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

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.

First was canceled no compensation second day was delayed Worst airline I have ever seen

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

Service was courteous and attentive. Sat in the exit row. In exchange for leg room I had people tripping over my feet to use it at a hallway from one aisle to the other, had no access to films viaa viewscreen and no underseat storage for medicines or other personal travel needs. Next time I am seated there, I will refuse the exit row.

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!

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".

The business class seat is the same as economy with 2 people instead of 3. That's not how it should be.

Checking in could not be done in the UK for this prt of the flight . Since we only had an hour and a bit at Singapore it was very stressful not knowing if we had appropriate seats. The flight itself was Ok and the 787 had a bit more legroom than the777 from Munich to Singapore. Food wasn't great.

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…….

They lost my Bebe stroller til today I can’t reach anybody to find my Bebe stroller

You get what you pay for. Beware 747/8 entertainment interface ...the touch screens are rubbish.

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