The seat did not recline and we called the stewardess, he forced it to recline, but when we landed, it did not come forward because the seat was broken. The stewardess came, He tried to do it but couldn't do it, the flight commander came and spoke to us in a bad tone, telling us to get out of here, she waited at the head and acted as if there was a child and we couldn't get up, it was very shameful, I don't even know if it's true, but she said if you don't get up, the plane will not land and will keep turning around. Then a passenger pushed the seat from behind and it worked. Then we wanted to talk to the supervisor again, but she did not come next to us. We fly so much and this is the first time we encountered such a style.

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Horrible. Boarding was terrible. For a huge airplane, we needed to be transported to the plane. The boarding area was overcrowded and frantic. .The seats were so uncomfortable. The food was fine.

Only chicken as a meat dish through out the flight

Nothing really was great as such. Seen other no name airlines perform better.

It was a nightmare. I booked business class ticket from Ediburgh to Beirut via Istanbul to attend a funeral. I had a wonderful experience flying to Istanbul from Edinburgh. Then I could not get a boarding pass issued to Beirut. It seems that although they booked me and I had a reservation number, I had no seat allocated and the flight was full. I was asked to go from one desk to another and made to wait for 2 hours. I missed my flight as I did not have a seat assigned and it was full. The only option was to put me on the next flight, 6 hours later, for a fee of over $400. They said that was the best they can do to 'help me' and to 'take it or leave it'. Well, I was not about to be bullied; I stood my ground. I booked and paid premium for the journey, which was confirmed. The eventually accepted to not charge me extra and i waited a total of over 8 hours in the airport with no compensation. On top of my grief with the risk of missing the funeral service, I had to put up with their indifference and condescending attitude. They spoke about me in Turkish thinking I would not understand (I hold a British passport) in front of me. When they eventually handed my passport and boarding pass back to me, I showed them I was born in Istanbul and that I understood everything and said a condescending 'thank you' back to them in Turkish. You should have seen their faces. I said that consumers have rights and it is a shame that Turkish Airlines does not have good customer service to at least acknowledge and apologize for errors committed by the airline. Blaming the me, the client, for such an error and placing unreasonable ultimatums, rudeness and dismissiveness to be rid of me, particularly when I was vulnerable and visibly grieving was really shocking... The airline taints the city of Istanbul and the people of Türkiye. Such a shame.

Was not able to check in online, so had to stand in line for 90 minutes to get a boarding pass, and I had no luggage to check. Why not let people check in in advance on line? Or at a kiosk at the airport?

Boarding did not have a clue what is an EU disability card

Not a good experience from Lagos was very terrible paying for one extra bag is #403,600 in dollars is $331 which is too high and when get to Ny I don’t receive my bag till 2nd day some of my stuff was damaged am not really happy with Turkish Airlines very poor services.

3 of us were in the business class. All good except the Flight out of Mumbai is too early. It is at 6:30 am. Reporting is at 4 am. We had to get up at 3 am. US connection has 4-5 hours of layover. It would be nicer to start the India flight late (give more time to sleep at home) and have less layover duration in IST.

Pegasus is not a very comfortable airline. They’re not in any way hospitable

It was like moving cattle around. Very abrupt, uncomfortable and not much hospitality

All good but air not give the pasing er any food even glase of water

Flight delayed by 1hr when we already boarded because someone had to get off. Leg room is terrible for 6ft people like me.

I used the airline 5-6 times for the last year and every flight have had perfect timing and I like it. Despite catastrophic absence of space for my legs 😁

The crew was utterly non helping and non courteous.I asked for a water. The air hostess could have said it's paid . She informed me that I will come later after serving but never turned up. The seats were never comfortable.My first and last flight with Pegasus.I am not taking again

The plane left Istanbul 1 hour late and the AC was not really working great it was so hot inside and no air. This was my worst flight in a long time since I had a flight with Ryanair.

Cheap and cheerful. It’s a super cheap, no frills flight. Very professional and as it’s an A320 relatively spacious. Seats do not recline. Happy with the service. You get what you pay for. Can’t complain

I had 4 flights for less than a week and there were no delays and issues. Thanks to the crews and for perfectly organised service.

There is no usb for charging the phone you should provide the water
