Airline reviews

The rules regarding business class lounge hotel/room access were very confusing. Between flights we had an 11 hour layover in Istanbul, but were denied a room to rest as our layover was too long?? Keep in mind that we arrived there at 3:30am after a long flight. Even multiple Turkish airlines employees were inconsistent with the rules. We ended up paying a high price at the Yotel in the airport in order to get some rest. Good thing I did, as a medical emergency was declared on the flight from Istanbul to Atlanta and I was apparently the only physician on board. Luckily I was able to stabilize the passenger and the flight wasn't diverted. The crew called an overhead announcement for a medical doctor, but insisted that I show them a copy of my medical license which I did. Very strange in my 35 years as a physician and responding multiple times to inflight medical emergencies over the years. I was very glad the passengers issue was resolved, but an acknowledgement of at least a thank you from the crew would have been appreciated.

Our flight attendant was stellar with great anticipation and attention to details. Food was very good, and overall flight, though very long, was really good.

Turkish Business Class is a wonderful experience, and the best inflight dining experience I’ve had to date.

They are absolutely impossible to get hold of. A death in the family caused us to delay our departure. They are impossible to get through to and after waiting 41/2 hours I was told they would not consider helping us. They cancelled our return flight and have not reimbursed anything. I strongly urge readers to consider a different airline.

Delicious food, comfortable and clean plane. It's a little cramped in the hall in front of the gate.

Absolute worst airline. Charged us $720 to check 4 bags (2 of which were carry-on). Entertainment systems didnt work. And on a 12 hour flight they served 2 meals and never once came around outside of those 2 meals with a beverage or cup of water. Will never fly them again.

Turkish Airlines is amazing. I have a problem with the ticket I purchased through the kayak website. I have filed a complaint related to the fact that I was contacted by phone on the day I purchased the ticket and told that the amount that the ticket had been advertised for was not accurate and that I had to pay more. This is totally fraudulent. I will look into addressing this further tomorrow and will never ever use kayak again.

Definitely not a fan of Turkish Airlines, their seats are very uncomfortable. Felt very cramped up. Food was very poor in quality too, very little to drink during service.

The seat in the 787 was broken and did not keep us in the upright position. Also the entertainment system was broken for some channels and only had audio and no visual display.

Long haul flight need to have better snack/food options. Toilets were not refreshed regularly. No toilet paper or hand wipe tissues.

Food was much better than my outbound flight. On-time. Good service. I had a problem with my entertainment screen, but the attendant fixed it promptly.

Food is delicious I’ve tried Thai green chicken curry and it was perfect!

I pre-ordered my meal and did not receive it. The seats are very old, uncomfortable and dirty. The crew was excellent and made my stay on board comfortable and enjoyable.

The only thing that the airport can improve which will help Lufthansa from delay flights is to warn the passengers that are flying to the USA to be earlier to the gate due to the documents check that in our case delayed the flight

SEA to Munich flight was turbulent and you could hear rattling in the plane. The food was TERRIBLE, return flight was better. We will not fly Lufthansa in the future.

Flight was very late, meaning a missed connection in Frankfurt, and staff completely unhelpful or just absent. Handicap accommodations, reserved in advance, somehow never made it through the system for the second trip in a row!

Flight was good, staff members were helpful and energetic, food can be more tasty.

During the boarding process women with small children were not invited to board first and were clumped into general crowd boarding, also during the 3 hr flight there was no food or water offered and I was traveling with a small child who needed water. I would appreciated that next time Luftansa informs that on 3 hr flight there would be no food or water offered so that I can prepare for the flight. In addition, traveling to the plane with the bus and then climbing up the stairs into the aircraft with small child and overhead luggage was probably the worst experience that I had in years traveling. Overall, will try to avoid traveling with Luftansa by all means. Thank you

Someones phone kept ringing and the flight assistant did nothing about it. Not even an announcement.

Fast boarding, great entertainment on board, lots of updates from the capitan during the trip, no lost luggage issues
