The service was great. However the lounge only gets passing grade

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

KLM is my favourite airline. Never ever let us down.Staff are first class.

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

Quick and efficient as always. Air France managed to loose and damage my luggage that never made it onto my KLM flight.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

It was nice to be on a legacy airline, people try at least.

I travel frequently. The flight was late again... KLM should really try and be on time

Everything was good except for the seating arrangements. We could not get seats to be seated together with my wife. We’re unfortunately.

My first time in business class The in flt staff was outstanding in every aspect of service, the food was amazing, the business seat space made the 11 hour journey easy peazy

It was good, but always can be better. The airplane was old.

I am a US citizen coming from Uganda to IST to LAX I was to be rerouted to Houston for Ebola health screen at no extra charge per TA app. At IST Turkish counter 4, they refused to reroute me to Houston unless I paid $1000. Finally, they said they would route me to Houston at no charge but not to LAX. SO I PUT OUT AN EXTRA $300 for Delta to LAX. IF THE US HAS A MANDATORY HEALTH SCREEN, THE AIRLINE NEEDS TO COMPENSATE THE PASSENGER NO EXTRA CHARGE TO FINAL DESTINATION

I always travel on Turkish Airlines but seriously I am I am considering to change because this is not the first time that the flight attendant are rude and they dont help. I asked for cold water with ice 5 times and I got water with no ice and this is not the first time to ask for something and you dont get it. Also I noticed this behavior only towards people who are not turkish.

Will be better if the flight will be on time

There were not enough extra leg room options to purchase. Also the seat Infront of mine was broken and the gentleman literally laid back into my lap for the whole trip. This was the most uncomfortable trip I have ever been on

A lot of things can be done to improve in flight experience

My flight was diverted to a different airport, not my intended destination. My initial flight was scheduled to Chicago Airport, but they changed it to Washington with just under 8 hours before my departure. As a result, I had to pay an additional $700 to book a new flight to my final destination. I tried contacting Kayak, but they were unable to assist me, even after purchasing travel insurance.

late arrival on a TK flight meant I missed my next TA flight. Had to wait a day to get a flight and they would not reschedule me all the way back to Denver. I had to buy a last-minute ticket from Washington Dulles to Denver on top of paying over $6000 for a business class ticket. I don't think I would ever fly Turkish Air again.

Not great!!! Seats in Business class were horrible; no cushion!!!

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

Gate was difficult to know. Flight number from Lufthansa directed to a different flight number by SunXpress, which was different from my actual flight per the airport. Multiple people (at least 3 others) were lost with me at the airport in Munich (I didn't know them) trying to get to a different terminal. Too many confusing signs, and no one could help. When I found some Staff members (surprisingly difficult) told me "you have to figure it out." Yeah, that's why I'm asking and walking around in circles. Thought I would miss my flight, turns out I had plenty of time, but I couldn't figure it out for the first hour. 90% airport's fault, not SunExpress.

Getting boarding pass for international connected flight was a hassle. Huge libe to get boarding pass after two connected international flight is excessive to put someone on stress. They should provide online checking for all flights

The most horrific experience we had with the airline that we had in our life Everything was substandard at best. For just one hot tea they charged 4 euros We paid for Lufthansa months in advance ,to get there they didn’t have us in record and after 4 and a half hours layover we almost we got one seat at the first row and one in the back of the plane On top of that our suitcase was seriously damaged and it’s unusable. Here we are halfway around the world in foreign language having to fix this on our vacation time Would you kindly and quickly resolve this matter

That was no easy way to get on board in the plane was very hot and I couldn’t talk to the crewmember there super rude and they couldn’t fix the AC. They felt very uncomfortable for 3 1/2 hours flight. I would not use airline next time. Thank you.

Unable to get Lufthanza code to obtain a boarding pass for my flight. Had to exit and re-register to get on the flight. Extremely frustrating.

My flight was delayed for more than an hour due to planning amd scheduling issues all of which were Lufthansa's responsibility. They failed dismally at doing what was agreed upon and their reparations were inadequate and completely useless to us. The flight crew were lovely however the ground crew working out of their customer service were the modt rude and obnoxious people i have ever had the misfortune of meeting.

My luggage is missing. No one can give me information on its whereabouts. I am frustrated. All my personal belongings and daily medications and other electronics are in that luggage which I need urgently.

The crew that checked at the gate was completely unprofessional, i had a child, stroller and a carry on luggage and the crew did not bother providing any help getting down 3 flight if stairs. I asked for hel and they ignored me

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

All good but air not give the pasing er any food even glase of water
