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

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 😁

Pros: "Not much to say here. It was a short flight, and it went smoothly."
Cons: "I’ll say the same thing about almost every flight I have, and this is mostly for the airlines. People might fly more and pay a bit more if you give us more room. Being crammed into a tiny seat with a bunch of strangers is never pleasant. Same in this flight. Nothing terrible, just the usual. Also, to the other passengers, sit down until it’s your turn to exit. What is wrong with you that you can’t sit five more minutes? Be polite and let the people in front of you go first, let them have room to grab their bags instead of having your elbows in their face."
Pros: "Everything except the delay"
Cons: "No delays, took bag crew forever to load the plane, they were extremely late....waited over 35minutes"

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

The flight attendants were great! The seating for business class is better on other airlines. The food was also good!

Great food, great entertainment and very helpful, caring & attentive staff.

Flight Singapore - Istanbul was perfect. Flight Istanbul - Sao Paolo - Buenos Aires was really good but there was a big delay in Sao Paolo (Brazil) due to a problem with the ground staff and not related to Turkish Airline. Overall a very good and solid experience

The segment bkk ist was ok. The segment ist to yul the boarding was chaotic with 5 control before get in the plain, in addition to normal control by scanner and metal detector during transfert

The in flight entertainment was very good but unfortunately I feel they could have been more attentive to the customer. This is saw on all my Turkish airlines flights , besides dinner service you never really saw the attendants.

The flight was great. From the first to the last step, the staff was very helpful and understanding. I also always enjoy Turkish Airlines food because it’s flavorful, fresh (like salads and very delicious bread ) and has special things like olives, dates… I loved that bean salad and apricot pie. I also enjoyed the movies. Thank you!

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

I recently flew with Turkish Airlines, and I can confidently say it was one of the best travel experiences I’ve ever had. From the moment I boarded, the crew was incredibly attentive, warm, and professional. They went above and beyond to ensure everyone was comfortable and well taken care of throughout the flight. The highlight, however, was the food! I’ve flown with many airlines, but Turkish Airlines sets the bar incredibly high when it comes to in-flight dining. Every meal was fresh, flavorful, and beautifully presented. The variety of dishes, even on a long-haul flight, was impressive. It felt like dining at a high-end restaurant at 35,000 feet! The seats were comfortable, the entertainment options were great, and the overall atmosphere made the journey enjoyable. Turkish Airlines truly excels in combining luxury and hospitality. I wouldn’t hesitate to fly with them again—highly recommend!

Very nice and friendly crew. Boarding system can be improved.

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

It was very good, good food good stuff, The toilets were a little stinky.

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

Pathetic service by underpriced, please call me back at the earliest

All was good. I would have preferred free drinks besides water (coffee/tea).

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

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.

My first two flights were late. I missed my last flight. The next flight was not until the next day Seating on large plane was uncomfortable. In the center row, there are posts that do not allow you to spread your legs. The entertainment center did not respond well. . Food was okay. Though there was much confusion about where the special meals that. People ordered(not me) went

Email noting gate change was good. Very bad: credit card machine broke down to charge for a checked bag. Lady at the counter read my credit card number OVER THE PHONE to a woman in Germany. Very insecure!!

Because of a thunder storm in JAX we spent more than an hour on the run way in the aircraft. The crew did not even offered water to passengers.

Two things to note here. First, Lufthansa separated me from my small children. Apparently you need to pay extra to ensure that your children are not abandoned. This is different from KLM-Air France, where children sit with their parents automatically, and I usually fly KLM-Air France. I didn't realize Lufthansa was different on this score and is willing to leverage the wellbeing of small children to generate more revenue. Second, my flight arrived 3 hours and 54 minutes late, so I am entitled to financial compensation as per EU passenger rights regulation. From other aspects of Lufthansa's behavior during this trip, I expect that their approach to this is to start a war of attrition with their passengers to avoid giving compensation as much as possible - again, very differently from KLM-Air France. But we'll see, maybe I'll be pleasantly surprised.
