We liked the comfort and seats. The crew was not very friendly nor did they check on us to see if we needed anything. Had to ask for water several times

We liked the comfort and seats. The crew was not very friendly nor did they check on us to see if we needed anything. Had to ask for water several times

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.

I wasn't able to bring my little dog with me, because of the feedback team's extremely slow response. How are they even allowed to operate with this paste??

The sleeper seats, the staff, and the food was truly delicious. I loved the mocktail options.

Great service. Seat was a bit small but it was fine. Food was great

Horrible service at the baggage claim. Stuck on plane for an hour due to taxing and no gate.

I really would like it if they provided at least some limited free wi-fi.

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

Same as before boarding process and lack of crew experience in the process

Excellent service. Made United 's business class look like a cattle car

Long line with check in at the DIA British Airway counter.

It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

Everything excellent except for bag drop off. We started at the D area and that was so slow that it was eventually closed just as we were about to go to a station. We then went to F. We got one suitcase checked and then the screen showed that the station was no longer operable. There were long lines everywhere so we had to ask if we could butt in to the next station to finish. Again, this was the only incident, otherwise it was an excellent flying experience

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

We never made it onto this flight due to BA's lackluster organisation.

We arrived late to London, and consequently were 5 min. late to be allowed through security for our next flight. Even though dozens of people missed the same flight, BA did not radio ahead to hold open security for an extra 5-10 min. to allow people to get on the flight. This caused an additional 6 hour delay in London after waiting over an hour in Customer Service to get rebooked. They did not have enough staff on hand to help people in a timely manner. Not at all happy with the BA's customer care or customer service.

Boarding was fairly chaotic. One of your employees clipped my ankle as he was passing with an empty wheelchair and not only did not apologize but stated something to the effect of “oh forGod’s sake.” There was plenty of room for him to pass. otherwise, everything was excellent.

Seating is tight if you don’t upgrade. Food was decent. Boarding and unboarding was efficient. Smooth flight. Could make upgrades more affordable

The seat was very uncomfortable. It helped to use the foot rest. Could not sleep because of the seat.

The crew was so unfriendly. Our (the last) section of the plane only got drink service once during an over 9 hour flight. When it come to the main meal service we only got a vegetarian option and where told the chicken option gone. About 30 minutes later I went to the bathroom and lo and behold the whole crew were eating the chicken option.
