The best airline food being served for business travellers. Excellent food.

The economy seat was so uncomfortable, had not enough leg room for 13 hours flight, front seat basket was broken and couldn’t hold anything, food quality was horrible( we got food poisoned ) we charged for logged which used to be free. We paid too much for this flight and very disappointed. Turkish air line better to make satisfy and respect people instead of find different way to scam people.

The business class seats are designed for someone taller than I am, so my feet were dangling (the footrest was just a smidge too low). Which caused problems with my sciatic nerve and made for a long uncomfortable flight.

Overall great airline that still provides two suitcases, has a huge hub and crew goes above and beyond to assist you. Boarding took a lot of time as there were only 2 people checking in. Also, in Istanbul, taxing took almost 30 min.

Very good overall.... apart from the cost of extra check ed in luggage where they charge £17 per kg, and no option to just buy an extra bag allowance (at least on the route I took)

Amazing! Big line at Check in was diminished in 10 minutes. Boarding was quick and efficient. Service and food great. Only minor point: seats could be a little broader and for me being small, something to put your feet on during the flight would be great.

Except for spending an extra day in Istanbul due to late departure from Athens on Saturday and missing the connection flight TK0044 to Cape Town and again arriving 45 min late on Monday in Cape Town, it was all good.

The best food I’ve ever been served on an airplane. The security at the gate was frustrating as was the heavy editing of the films and television shows offered.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

It was an old airline with the old configuration of business class seats. Not really what we signed up for for the longest leg of the trip. Disappointing.

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.

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

Pegasus is a very efficient airline. Passengers, however are sometimes unruly. Getting up right after take off. Getting up right when we land and before getting to the gate. Switching seats to the front so she can get a better seat. It is unfair for those that actually paid for seats. Flight attendants seem to not enforce it. One or two bad actors ruins it. Overall, the airline is great.

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

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