One of the worst days of my in Istanbul very disrespect people they changed my flight 2 times I miss one of my flight from Istanbul to DFW they forsed me to buy another ticket they do not care about customer they take advantage of you. You get scammed from every where if have other options please don't go through the Turkish airlines

Surprised for charged $341.00 FOR my luggage. THY opportunist, taken advantage of the people not knowing luggage must be paid.. I flew 7 months ago with Lufthansa same place to Los Angeles my family lives and work in L.A. no luggage PAYS BIG zero .. I WILL NEVER TAKE ANY FLIGHTS ✈️ FROM TURKISH AIRLINES EVER AGAIN 😒 Please Don't recommend TURKISH Airlines to nobody.. I am a retired person. With very limited S.S. check for a month..$341.00 is my kitchen expenses for at list 5 weeks i am a vegetarian salads and sandwiches.. thank you very much for your investigation asking my experience about the flight with ROTTEN Airlines 😀

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

The crew was not professional enough for that time. Multimedia connection had a problem frequently

I already checked in online and provided with a window seat by default which was OK with me. When I printed the pass at the airport, I found that the seat number was different (aisle but in same row). By that time, all window seats were taken up, I am surprised that TK can unilaterally change seats after completed online checkin.

What I did not like was that the airline changed my seat in Bodrum to one that was not in business class. Up until that moment I was in seat 1A. Then suddenly they told me I was in seat 1K and my "tablet was not working". - meaning my tv screen. I said that was not ok and they said go tell them in Istanbul. Each Turkish Air rep that I consulted told me there were no available seats in Business class. Finally I talked to the 4 airline representatives outside the lounge. When I talked to a woman and explained I wanted to change my seat back to what I had, A lady consulted something, asked me if I signed anything, then turned to a man nearby and spoke in Turkish. The man consulted someone and spoke in Turkish to the woman. Then she said my seat was now A1. Why was my seat changed out of business class in the first place? What would have happened if I had not talked to someone at the lounge? I am totally confused.

Seats were in disrepair. Seat back pockets were all broken. Seats recline very far, which is comfortable for occupant, but confining for person behind.

Plane was hot in our section of aircraft making it difficult to rest. We informed the staff but adjustments were not made. Seats were terribly uncomfortable- unlike the other long haul flights we have flown on Turkish Airlines. It seems both issues are due to plane being an older Airbus

Turkish airlines always is an excellent airline, bottle water, comfort kits were provided. Decent food on board, friendly staffs.

Check in, was fine, boarding was good, we left on time, punctual flight, aircraft condition was also good, Boeing 737-600 , all went well, I did not expect more or any better

Flight changed and cancelled several times over the months in advance that I booked it. However, actual flight went well, no delays, spacious seats. Had some landing issues but otherwise, fine. Also loved that they don’t check weight of luggage!

Seats are disaster, not comfortable at all. With my height 183 cm there were no space for my legs... The airplane was Turkish airlines and no entertainment on board.

Bad. Cancelled and delayed flight. Payed 25£ for seat but got just normal one. No one refunded the money.

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

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 😁
