I am always amazed with the great service they offer on their regional and international flights

Nothing luxury about Turkish airline compared to many other airlines

Entertainment was good. Flight was delayed, nearly missed my connecting flight. The gate was changed on several occasions. My luggage did not arrive on time and had to leave without it.

Service was slow and checked bag was off last evening when flying business

Everything was good except that they didn’t give us seat for our connecting flight in Istanbul from Cairo. This created a panic situation. Hopefully they give all customers connecting flights seats right from the start.

Requested food items were always finished but the available food was warm and tasted good Good entertainment options.

Bad chairs in business class like economy ( not turning into bed )

The entertainment selection itself was ok but the screen couldn't be turned off which was annoying because I wanted to read and not be distubed by flashing lights in front of me. I could see other people having the same problem with their screens. The crew seemed to be too busy to be bothered by our questions/requests. I found the seat quite uncomfortable, especially for a long flight. As a short person, I've accepted the inconvenience of always having seats higher than comfortable, but my neck hurt after a while because the headrest was too high and couldn't be adjusted further. The seat pockets in this plane seemed to be faulty. I could see people near me having the same problem of everything falling on the floor because it kept detaching from the back of the seat. It was pretty useless to keep anything in it, even the menu and sick bag wouldn't stay in. The food was meh. The omellete was just a hunk of egg - my next flight leg also offered omellete but was so much better than this one.

Space between seats is challenging but otherwise excellent service in every way.

Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Late. And service was very slow - passengers sat for well over an hour with dirty trays etc surrounding them

Entertainment devices on A380 need to be fixed, the seats might do with updates.

I like everything about British Airways. Excellence. Perfect. Exquisite service.

The plane was dirty the food was awful and the boarding process took too long

Everything. Employees offered to help me because I had to use a cane.
