It was good but Food I didn’t get as per choice, I asked for Non veg but I got veg . Entertainment, there is no Panjabi movies and Hindi movies also almost same which was a year ago .

Boarding is chaotic and confusing but otherwise it was fine.

Very good in general but we were assigned seats in different rows.

On plane great. Everything else needs improvement. Missed both connecting flights because of flight delays. The directions to go to the hotel desk were terrible. On the flight here I mistakenly went to wrong “hotel” both and got hoodwinked into paying for transportation and stayed in lesser hotel. The staff at airport were not helpful and signage is not clear. Next time I will fly different airline. Not sure how they got such a high rating with how they manage flights at Istanbul. Also the flight temp is hotter than any other carrier I have flown.

First Flight got delayed had to get rebook for another plane ride to connect the next day the process was not helpful at all had to figure the whole processs myself poor service plane was small and customer service was horrible will not fly this airline again

Boarding took long and there was a long queue. The seat didn't recline. The crew didn't have access to any medicine.

Excellent overall. Boarding was a mess. Queue up too early, takes too long for them to start boarding but they want everyone to queue up and wait and wait.

The boarding process was a disaster. I was comfortably seated in the lounge at Athens when I got a notice the flight was boarding so I rushed to the gate. When I arrived, it was NOT boarding and we waited an additional 10 minutes before boarding started. There were no announcements regarding the order in which passengers should board and it was a bums’ rush. A total mess.

Turkish Airlines changed our business class seats at the last minute and said it was a computer glitch. No other airlines has had this glitch. The steak was like leather and nobody could eat it. The boarding process was extremely slow and we had to stand and wait in line for over an hour in EWR and almost as long in IST. Again while coming back our seats were changed from row 3 to row 6 for no reason. The food was a lot better from IST to EWR. The service was poor from EWR to IST and good coming back.

Boardings in Newark and Istanbul were kind of chaos. Dedicated lines for assigned seats seems to be a smart idea, but most of the people were getting confused and were going back and forth. The agents were yelling where to go. The food was limited. Whatever we asked, they were out of it. For example, I would imagine that most of the people would prefer chicken over pasta. By the time they reached us, only pasta was available. For a long flight, in our case almost 11 hours, it’s very uncomfortable to remain put in the seat where not enough space to stretch the legs. But this is the another story about economy and upgraded flights.

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

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

Gate was difficult to know. Flight number from Lufthansa directed to a different flight number by SunXpress, which was different from my actual flight per the airport. Multiple people (at least 3 others) were lost with me at the airport in Munich (I didn't know them) trying to get to a different terminal. Too many confusing signs, and no one could help. When I found some Staff members (surprisingly difficult) told me "you have to figure it out." Yeah, that's why I'm asking and walking around in circles. Thought I would miss my flight, turns out I had plenty of time, but I couldn't figure it out for the first hour. 90% airport's fault, not SunExpress.

Getting boarding pass for international connected flight was a hassle. Huge libe to get boarding pass after two connected international flight is excessive to put someone on stress. They should provide online checking for all flights

The most horrific experience we had with the airline that we had in our life Everything was substandard at best. For just one hot tea they charged 4 euros We paid for Lufthansa months in advance ,to get there they didn’t have us in record and after 4 and a half hours layover we almost we got one seat at the first row and one in the back of the plane On top of that our suitcase was seriously damaged and it’s unusable. Here we are halfway around the world in foreign language having to fix this on our vacation time Would you kindly and quickly resolve this matter

That was no easy way to get on board in the plane was very hot and I couldn’t talk to the crewmember there super rude and they couldn’t fix the AC. They felt very uncomfortable for 3 1/2 hours flight. I would not use airline next time. Thank you.

Unable to get Lufthanza code to obtain a boarding pass for my flight. Had to exit and re-register to get on the flight. Extremely frustrating.

My flight was delayed for more than an hour due to planning amd scheduling issues all of which were Lufthansa's responsibility. They failed dismally at doing what was agreed upon and their reparations were inadequate and completely useless to us. The flight crew were lovely however the ground crew working out of their customer service were the modt rude and obnoxious people i have ever had the misfortune of meeting.

My luggage is missing. No one can give me information on its whereabouts. I am frustrated. All my personal belongings and daily medications and other electronics are in that luggage which I need urgently.

The crew that checked at the gate was completely unprofessional, i had a child, stroller and a carry on luggage and the crew did not bother providing any help getting down 3 flight if stairs. I asked for hel and they ignored me

I resent being called a ‘guest’ of Pegasus airlines and then they refuse to give me water, because they want to sell it to me. Also, the baggage allowances are ridiculously stingy. I also resent the way staff are on the look out to catch passengers out. I would never dream of treating my ‘guests’ like Pegasus treats us.

Great flight and great crew. Many thanks to them for their hard work making our trip so relaxing.

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.

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.

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

Late departure. No announcements. Boarding was a disaster. Some kind of technical issue scanning boarding passes.

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
