More room. International flight - by the time you put your purse and shoes under the seat in front of you, add in the pillow and blanket they give you- makes for tight fit.

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

3 hour delay on run way, not even a drink offered, staff seemed rude and rushed, felt unwell so asked twice for paracetamol and was told to wait, never got it

First time flying internationally with AA and probably my last. Not military friendly at all. Didn't allow free checked bag for military family members (dependents) on orders like other airlines. We were charged $100 for baggage weight overage (5 lbs!)even though we had military orders allowing us extra.. Didn’t allow military members to board early. Inefficient and long wait time to board. Seats are smaller and more uncomfortable than other airlines.. no drink service for over 7 hrs of flight! After initial meal was served, the crew never offered a snack or drinks until the breakfast's was served 1 1/2 hrs before landing. Overall expensive and poor experience for the entire flight.

Boarding process was good. I was assigned the most rear (non-reclining) seat in both directions, which wasn't great.

not enough crew for business class and not great service as a result. underwhelmed overall

The crew was very helpful and the aircraft was clean. More attentiveness to us in business class.

Crew never smiled, never helped , told me to make my own bed ( in Upper class), never offered a drink

British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️

3 hr delay. No water given while on the plane for 3hrs.

No fast track available, no organisation. Unpleasant boarding system at gate 20 at JFK. When giving feedback to the lounge team I was told to talk to the manager instead of taking the feedback.

The whole experience was great. The only improvement would be the entertainment selection

I will travel by BA only in future also. Only suggestion is they should give aisle seat in front near washroom for senior citizens

It was good overall. Entertainment was ok, one of the TV screens had issue. Bit old plane but leg space was good. Overhead luggage had good space. The worst part was experience at Heathrow airport, it was total chaos.

Comfortable, pleasant staff, quiet, good entertainment, food, drinks. Better than American (flight back) when we were crammed in and staff sometimes indifferent.

Pretty disappointing. Paid for business class. It was burning up the entire flight. For a 7 hr flight, after the first few hrs. The crew disappeared. Poor service.

One frustration after another. No gate personnel until very close to departure. Boarding procedure was chaos. Plane was dirty from previous transatlantic flight. Entertainment system not operational. Gate change for connecting flight which required another round of security clearance, almost causing a missed flight. The final blow was lost baggage upon arrival.

CVG to London was a good flight . Thank god the plane was not full . Seating was tighter than any international I’ve taken . We arrived in London 10 minutes early. Had it not been for handicap assistance I would have missed my connection. Had it not been for the extra 10 minutes because we landed early I would have missed my flight . 3 hours and 10 minutes from plane to plane as they were boarding when I arrived . None of that is the fault of British Air but the understaffed and confided security at LHR. Because of this I will never use British Air again unless I don’t land in London . Not the airlines fault but I never want to miss a flight because of the blunder in London . The worst I’ve ever encountered in international travel . Sorry British Air but your home needs better management.
