Flight was on time and the flight crew was very friendly and they were able to answer questions in English very easily. My bag came out fast in stockholm.

Was great but they would not book my bag through to my final destination

First they postponed the departure from 20.20 to 02.05 - almost 6 hours. Then all communication stopped. At app. 23.30 all info boards confirmed that the plane was finally cancelled. And after a sleepless night I realised that two contradicting messages had been received: At 01.59 passengers were directed to board - at the opposite end of CPH Airport - as the plane would take-off at 02.05 and at 02.42 CPH Airport Authority (official traffic information) confirmed that plane was again-again cancelled. Irreparable image!

It's fine if you don't want to give free water or anything, but don't try to sell the food in first class like there is a chef that actively made the food from the finest local ingredients. Its still plane food and the chef hasn't been near that food for quite some time

I was very disappointed because a special assistance wasn’t given to me and water was given to me in 50 min after I asked about it.Poor service,

Smooth flight. Surprisingly good and inexpensive food choices. Clean cabin. The plane is not equipped with the entertainment system.

Failure of APU meant massive delays at start of journey , baking in an unventilated plane Not good

Delay ca 5 hours on the first flight and 2 hours on the next one

The airline ran late and I almost missed this connecting flight to LGW. The airline didn't act very sympathetic to my situation. I wished that didn't happen as my experience I'm sure would've been much different.

One flight has delayed, but connecting flight ( the same company) has another plan for us. And left TO TLL. Instead Finnair.Who waiting pax from BRUSSELS. GREAT EXAMPLE OF COOPERATION. 👍

Turkish Airlines was great. My new layover was over 18 hours due to inclement weather back home in Washington DC and the airlines provided me with a hotel room and dinner voucher during my layover

Bad sitting every flight not good experience with food either

My, Syed Zawar Hussein Shirazi frequently flyer membership number was not included on my boarding pass from O’Hare to Istanbul despite my reminder to the attendant at check in. Further she forgot to give me my boarding pass form Istanbul to Lahore and she needs to improve her customer service, please 🙏

Everything about that day was great I was happy with how things went as a first time traveling with the airline thank you for all that you’ve doing by taking us there to our various destinations thanks.

The seats were extremely small. Boarding was not communicated correctly. It wasn’t a pleasant trip.

I am always amazed with the great service they offer on their regional and international flights

Nothing luxury about Turkish airline compared to many other airlines

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.

Service was slow and checked bag was off last evening when flying business

Everything was good except that they didn’t give us seat for our connecting flight in Istanbul from Cairo. This created a panic situation. Hopefully they give all customers connecting flights seats right from the start.

The plane was too hot inside. There was no entertainment and we had to sit on the plane for one hour before takeoff. There was no free wifi.

Online check-in was unavailable for my flight. So I waited 40 min in the queue at the check-in counter. Then, unlike any other airline in the world (and I am a very frequent international flyer) Pegasus was adamant that my CPAP was just another carry on and that I had to pay extra for it. Then, after I had paid in advance for a seat, they insisted I could not sit in an exit row because I was over 60 years old (I'm clearly in good shape and buy exit row seats more or less weekly). We pushed back harder and harder and insisted on talking to the station chief, who spoke with the counter staff by phone (not to me) and eventually relented. Experience on boarf was ok-- for a budget airline.

You adjourned my flight by 1h 30 mns and only updated me 1h30 mns before the new scheduled flight. I submitted an email to Kayak asking for a refund. It was the most stressful experience I've had.

Not because when i try to do check in there is only in turkish language i can not select other language

Don't fly Pegasus, terrible service at the airport and boarding was really bad. Both flights I took with them were significantly late. This flight had us all changing the gate at the last moment and it was chaos.withour explanation or apology. The planes have seats that don't recline and seats are really hard. The crew on board was good both flights, but that is the only positive thing I can say about this airline. It's not worth it and I won't be flying them again.

The airport staff were some of the worst I've ever flown, and I fly at least 50x every year. From the staff at the gate, to the check in staff, to the ticketing sales staff. My experience in Instanbul was so bad Ill.never fly Pegasus again. They were incredibly rude, dismissive and not helpful whatsoever. This is the worst of the worst if you want to fly a budget airline I'd go elsewhere. The airplane seats are really uncomfortable and don't recline at all, you get charged for every single thing so in the end you will pay more flying with them. The crew on the plane were the only kind people we encountered with Pegasus.

Pegasus Airlines which is the most efficient and cost worth low cost airline all over the Europe

Flight from London was delayed and we had to hurry up to catch the connecting flight to Riyadh

The crew were outstandingly kind and cheerful. We carried our cat and they offered help.
