Flight was late but loading plane was much easier in Istanbul than athens. Food was so-so and choice was limited. Flight attendants were extremely courteous and helpful; however, it was difficult to get attention during night time service. Overall good experience and the price was right

Flight was late but loading plane was much easier in Istanbul than athens. Food was so-so and choice was limited. Flight attendants were extremely courteous and helpful; however, it was difficult to get attention during night time service. Overall good experience and the price was right

Turkish Airlines is a solid airline. They use the less trustworthy Boeing airplanes on this route (VCE-IST) so the flights more bumpy then when I have flown on Airbus planes, but it was okay. The service good. They seem to offer a reasonable selection if movies, although no way to listen to them as they didn't provide me earpieces. The food was surprisingly good. The day was uncomfortable. The flight was on time.

Food and crew were superb. I flu with a 777 which has old TV screens. Although the movie selection was very good, screen was not sharp enough to wacht a movie

Poor connecting flight logistics and ground transportation for such enormous airport. Airline does not consider time required to complete the security check or transition from one to gate to another

Food wasn’t good but not their fault as I should have pre selected

The seats seems abit small and the reclining is too much, the seat in front of me came back too much and made it uncomfortable for me.

The crew were kind and very helpful. Did not expect food service. Was served a warm soft sandwich bread , was delicious. Overall the service, the staff were great. Highly recommend others to try Turkish Airline

As a first time flyer with Turkish Airlines. My experience was very good due to the factor that there were to many passengers on the my first flight compared to my connecting flight. However, I know that nothing is perfect and all companies are trying to accommodate their passengers to the best way possible. I will always say, a FEW INCHES will go LONG WAY. That's something all airliners should consider, and not only the money aspect!!! A long time commitment is better than one time service! Thank you

Bag service at Iad airport was not nice at all. They served economy class first unvip first. This happened many times with different airports

We had requested a wheel chair assist for my husband who has Parkinson’s. The first seat we came to we got off the plane was staffed by 3 men-one was on his cell phone, one was sleeping and the fellow we spoke with was rude and seemed as if he didn’t care that we had a plane to catch in one hour. A person with a wheel chair came and took us to the center area for wheelchairs. Here we waited for 20-25 minutes while our flight went to “boarding.” Finally a woman came with a cart and we zipped through the airport.

I alrady responded to this request, and expllaned at length that this was the worst flying experience in my 77 years. I will NEVER fly BA again.

Airbus A350 is poorly designed for wheelchair users and reduced mobility passengers. The angle of the pods makes it awkward to transfer. I was able to but I have ab stability. It could be a real challenge for people with more severe mobility impairments. You'd think Airbus would have come up with a solution for this or thought more about us disabled folks more when designing this aircraft.

The crew has always been great on BA. They are very friendly and accommodating. I like that they have vegetarian options already in the menu. And the free wine is a nice perk.) I noticed (both directions of my trip) minor upgrades/ replacements needed on the plane itself (touch screen didn't work with touch; bathroom light didn't go on). However, this is one of my favorite airlines.

It was not British Air, we were put onto Air Portugal for our London to Lisbon leg.

Everything was spectacular except the boarding. It was just a mob of people while all groups were called over the public address system.

The Britts are wonderful to fly with and the crew were very hospitable. Again, I really wish they had been able to retrieve my carryon bag from baggage claim before the flight so I could be in a less worrisome state of mind, but that's not on them. I completely understand. The window seats with the dimmable windows were very cool!

There was a delay for the San Francisco-London flight, but we were all informed via text and email. The staff was very friendly and nice and the food was good. I do recommend that the airline offer something without eggs or something vegan for the vegetarian meal option. A lot of Indians are lacto-vegetarian, while some could be allergic to eggs/dairy.

food options were terrible. for a 10-hour flight, there should be 2 decent meals. Also, flight attendants should come around with drinks more than just at the meals.

Smooth flight. The seats were comfortable but the reclining mechanism didn't work very well. My wife's seat required the flight attendant to push the seat forward while she pushed the button. The leg support didn't want to return to its home under the seat. I ordered the diabetic meal which was full of carbs. It was low in sugar but carbs turn into sugar so was it really diabetic? Overall the flight was pleasant, long but pleasant.

Crew were nice, food was good. Boarding was horrendous. We were driven around the airport in a bus forced to climb a long flight of very steep stairs with no adequate handrails to board the plane . In many many years of flying to the US I have never been required to do this . There was no assistance for those needing help getting up the stairs to the plane. A fellow passenger helped me. No idea how other elderly, physically limited passengers or those with young children managed . It was a full flight with crowds trying to get up the stairs. It was an accident waiting to happen.
