Experience was great overall. However, the connection time between my flights (1hr 15 mins) was too short. We had to get through security check and US immigration in that time, and I made it to the gate just as they were announcing it was about to close. Flights with such a short connection time should maybe not be offered for purchase, or an advance alert would be helpful. Other than that the in-flight experience was excellent, especially the food. Many thanks!

The seats needs to be comfortables, at least please add more padding to the seats.

Incredible service. Incredible entertainment. I felt like they just kept serving us something new avery hour. My wife and I both had a joyous flight.

They out me in the baby row so I was surrounded by toddlers, they also did not send my luggage and was not able to book my connecting flight

I was so grateful for the kindness of the crew. They made a long trip very pleasant. Food was delicious. Many movie options

My flight from Dublin was delayed two hours which ment that I missed my connecting flight to Phoenix. American Airlines provided a hotel room and rebooked my flight for 7:30 AM the next day. I didn't get to the room until 11 pm and I had to be at the airport the next day by 5 AM. The airlines did their best but the schedule was challenging for an 81 year old.

Dinner was fabulous. Would have enjoyed a wine with it. None offered... for sale??? Breakfast was disappointing but adequate amount of food.

Excellent flight and crew. Boarding at Dublin Airport was a very difficult trying to find the right gate.

Dublin airport is big and US Customs and Immigration screening officers are is part of the process there. This eliminates screening upon arrival to US, however should be taken into consideration when playing your transfer. After all, pleasant experience enhanced by draft Guinness and Irish coffee at the buffet area near the gate. We loved boarding by the row, back of the airplane first.

There was a mixup with our tickets. They said they did not receive payment for them but yet we had seat assignments. We had to purchase last-minute tickets which cost us three times as much. that’s why they got a rated of a one.

It is a wonderful airline. The cabin crews were friendly and the food as well as the service the were excellent.

Good but could be better for comfort and entertainment aspect

Overall it was not a pleasant experience, I was given the middle seat even though I asked for a change they didn’t honor

No WiFi working on either flight. No leg room at all, the seat in front of me left dents in my knees. If I put the tray down, it was so low it was propped up by my knees. (I’m only 182.9 cm) I’m usually cool on planes, but the planes were both hot during taxi and take-off.

Very bad.i will never book British flights for future

Moved me away from my family and refused to fix it.

I noticed the crew was so much nicer and friendlier. It would be nice if British Airways would serve soft drinks during the flight

Must have had an elderly tour on the trip. Plane boarded via tarmac and had both front and tail stairway access. We waited about ten minutes at the rear entrance while elderly folks entered the forward access and walked all the way back to last rows of the aircraft! We could not access the row until every one of them finally reached the final rows. There should have been an agent directing folks Forward and Aft based on seat row. It was comical.

The airport experience at check-in, just to drop a bag, was horrible. The were two agents working, two watching. We stood in line for just short of one hour. I asked the agent if this were normal and he said, "Well, yes. Just two computer terminals." No apologies. BA needs to fix this ASAP. Meanwhile, I've moved BA to the very bottom of my booking list.

Good shuttle to Europe. Face check boarding needs overhaul. 2 stations for 200 people and still with passport check. Why have both? Why is this now slower than 5 years ago?
