budget airline, not a lot of amenities but perfectly priced for a 3.5hr flight. Crew/Pilots were great, communicative, and overall provided a great experience for the price point. Have flown with Norwegian when coming in/out of Norway for the past x10 years now!

budget airline, not a lot of amenities but perfectly priced for a 3.5hr flight. Crew/Pilots were great, communicative, and overall provided a great experience for the price point. Have flown with Norwegian when coming in/out of Norway for the past x10 years now!

Unfriendly staff at boarding gate. Unclear announcement at about gate change. Low cost airline with no amenities on board. Bring your own water.

Terrible communication about cancellation of flight. Put on a flight the day after our departure day even though there were seats the following day

…not even a power outlet. Nothing but uncomfortable seating with unhelpful staff.

Overall flight was fantastic.i really enjoy the whole journey .

Little more legroom would have been nice. But it's a very short flight, so it was fine really.

Short flight, some waiting to board, but no issues and no frills.

No staff at the gate and the flights were not posted on the board so we missed our flight. Horrible experience. Be VERY careful flying Norwegian. Super limited ability to communicate with their slim staffing and restricted hours.

Tickets were cheap but it says no where that food was not included, I travel Austrian, Swiss and Turkish airlines all the time always food is included, never flew Norwegian again

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.

Requested food items were always finished but the available food was warm and tasted good Good entertainment options.

Bad chairs in business class like economy ( not turning into bed )

The entertainment selection itself was ok but the screen couldn't be turned off which was annoying because I wanted to read and not be distubed by flashing lights in front of me. I could see other people having the same problem with their screens. The crew seemed to be too busy to be bothered by our questions/requests. I found the seat quite uncomfortable, especially for a long flight. As a short person, I've accepted the inconvenience of always having seats higher than comfortable, but my neck hurt after a while because the headrest was too high and couldn't be adjusted further. The seat pockets in this plane seemed to be faulty. I could see people near me having the same problem of everything falling on the floor because it kept detaching from the back of the seat. It was pretty useless to keep anything in it, even the menu and sick bag wouldn't stay in. The food was meh. The omellete was just a hunk of egg - my next flight leg also offered omellete but was so much better than this one.

Space between seats is challenging but otherwise excellent service in every way.

Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

PLEASE GIVRE US PERMISSION TO BOOK SEAT NUMBER EVEN WITH FEES

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

https://www.instagram.com/reel/DGVSRsasQcG/?igsh=dmkxa2s1eHNlbHZs

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.
