Was great but they would not book my bag through to my final destination

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. 👍

Great leg room and very clean plane nothing could be better 😁

THE SEATS ARE A JOKE!!!! YOU CALL THIS BUSINESS CLASS SEATS ? ITS A DISGRACE.. NARROW, CLAUSTRIPHOBIC SEATS CAN NEVER BE COMPENSATED FOR BY FOCUSING ON BETTER WUALITY FOOD SERVED....... THE CONFORT OF THE SEATS AND THE WIDTH & PITCH OF THE SEATS ARE WAY MORE IMP. THAN FOOD THAT TK IS FOCUSING ON... WILL NEVER FLY AGAIN EVEN IF THE PRICE OF BUSINESS CLASS SEAT IS SAME AS ECONOMY CLASS..... JAL/ QATAR/ EMIRATES HAS WAYYYY MORE COMFY SEATS

Rude staff. I would avoid using the word racist but definitely partially or discriminatory. My 72 yrs old mother who is also disabled was traveling on this flight. She was the second passenger boarded to the plane. The First elderly couple ahead of my mother were allowed to use the airplane bathroom but my mother was denied entry stating it was for safety reasons. My mother objected the the couple in front of her were allowed but hostess still stated that due to the flight safety reasons she can’t use it. Even my mother explained that he is using blood pressure medication that’s why she have to use the restroom frequently but the crew continued arguing her. At one point the Mae attendent even suggested that if that’s the case my mother can urinate in her seat. The level of disrespect against an elderly lady is beyond my comprehension. This matter will be taken to the social media to shame the employees involved.

my experience was great with Turkish airlines . the problem i encountered was with kayak booking. When I booked . it showed that im allowed a bag . and when I got to the airport, i had to pay $165 for one bag.

Not up to Business Class standards. Two of the three toilets were out of order. The hostesses were aware and didn’t show any responsible act to do something. Food quality was not what we expect from Turkish hospitality. Overall we were not impressed and disappointed.

During mid flight, try to get a flight attendant to help I couldn’t find one Otherwise, everything was perfect

I was not given basinett seat.The connecting flight was missed due to airline fault i was not accomodated for hotel.Drinks were normt served frewuently.Never travelling again on tirkish airlines.I always travel wiyh family by turkish airline but no more.zero stars

It was ok. Not the experience I expected from Turkish airlines

I loved and appreciated the agent at the check in counter in Amman. He was very professional and helpful. I believe his name was Lawrence. All I saw from him were smiles after smiles after smile. Very kind and professional. Overall trip was comfortable and pleasant.

The crew were very hospitable and pleasant. The food was pretty good. Unfortunately, there was a flight delay of more than 2 hours. We're not sure why but it appeared to be outside the control of Turkish Airlines.

Terrible. Delayed. No one would help. Just limped about like a piece of meat

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.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

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).

Staff very helpful. Seat comfortable. Food generous and pretty good.

More legroom (I am 6’4”) and my knees were in the back of the seat in front of me. Food was laughable

Good flight. Entertainment equipment was sub-par - old-style 2-prong jack headphones that don't fir ears well. Entertainment software interface was slow and glitchy to navigate.

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
