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. 👍

The ground crew members at check in counter were courteous. The boarding was seamless. Flight departed as scheduled. Service on board was great

Turkish Airlines lost my reservation!!! I had the ticket, the receipt and they lost it!! Because the flight was fully booked, I had to wait 8 hours!!! Turkish Airlines provided me with NO FOOD, NO WATER!!! Absolutely ridiculous. They were pathetic. They admitted it was their fault for losing my reservation but provided me with nothing.

everything was excellent except for the meal on the fight from the Istanbul which was disgusting, the only choice of food available was pasta which was served frozen.

Very comfortable in business class. Excellent service. Good food. Smooth trip.

This was my third time using Turkish Airlines. I was well satisfied with the overall experience! I believe that no one is perfect and that everyday we are trying to do the best we can to help others by giving a part of our lives through service. I believe from what I’ve seen that Turkish Airlines, have come close to that service! I will definitely recommend and reuse their services again! Thank you!

Flight was late but loading plane was much easier in Istanbul than athens. Food was so-so and choice was limited. Flight attendants were extremely courteous and helpful; however, it was difficult to get attention during night time service. Overall good experience and the price was right

Turkish Airlines is a solid airline. They use the less trustworthy Boeing airplanes on this route (VCE-IST) so the flights more bumpy then when I have flown on Airbus planes, but it was okay. The service good. They seem to offer a reasonable selection if movies, although no way to listen to them as they didn't provide me earpieces. The food was surprisingly good. The day was uncomfortable. The flight was on time.

Food and crew were superb. I flu with a 777 which has old TV screens. Although the movie selection was very good, screen was not sharp enough to wacht a movie

Poor connecting flight logistics and ground transportation for such enormous airport. Airline does not consider time required to complete the security check or transition from one to gate to another

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

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

flight was half full, plenty of empty seats, was able to lie down across 4 seats, food was good, arrived on time

Not great!!! Seats in Business class were horrible; no cushion!!!

The seat space seemed small especially when the person ahead reclined but other than that, very good.

One one boarding scanner was working to scan 400+ passengers to an Airbus 380. Food in premium economy was mediocre.

Insulting. Lufthansa flight from Munich to EWR had us getting our luggage when we were told in Florence that it would follow us to Indianapolis. It did not. Then very slow security in EWR caused me and three other passengers from Lufthansa flight from Munich to miss the boarding closure. Behind me were two elderly grandparents and their ten year old grandson. We were all refused entry on a plane to Indy that was still at the gate. The doors had not even closed inside the terminal yet. No apologies or compensation offered. Not even a meal voucher let alone a free hotel stay for our inconvenience. I m not sure what the other three passengers behind me did ( they were elderly with a grandson, recall), but I stated 12 hours overnight in a chilly EWR airport until next flight to Indy at 850 next morning.

The food could be better, more snacks. And have some plugs to chargue the phone.

No entertainment since it was a 3 hr flight. Good leg room for economy.

If I book through Lufthansa, I expect to fly on Lufthansa, not discover. Food was bad, plane was delayed. Will not be flying Lufthansa again.

All was good. I would have preferred free drinks besides water (coffee/tea).

It was a safe flight with a friendly cabin crew.

The flight was never confirmed, I was not sent a ticket, and my account was charged for this flight. I’m trying to get my money back for a flight that was not booked or confirmed. Terrible experience

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
