The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

My flight being automatically moved messed up my travel plans, and I had to quickly find an alternative mode of transportation. I couldn’t get a refund from any of the companies involved. Kayak, Ibiza, or Vueling. I am still unsure of how to settle my concern.

Plane delayed due to weather. Plane boarded, then told to unboard due to a maintenance issue.

I've taken British Airways before and it has been great. On this trip to Spain and Portugal we had two BA flights. On both flights we were taken by bus from the terminal out to the plane on the tarmac. There were many older folks on these flights, and to ask people in their 70s to lug their carry-on and personal items up the long mobile staircase to the plane entrance, is very disturbing. I won't be taking British Airways in the future. Many people on these flights were very unhappy.

The food on the flight was of marginal quality. Small bits of chicken, instant mashed potatoes and some carrots. The rolls were very dry, nearly inedible. The seats were quite small and didn’t allow for any shifting of position during the flight. There was limited leg room.0

Terrible customer service. I booked business class and the counter agent didn’t bother asking me about any choice or preferred seat, basically assigned me that last seat and couldn’t even answer if it was a business class seat. Also iberia lost my suitcase on my flight from JFK to MAD with the layover in BCN. Useless customer service at the counter. Thank goodness I happened to check the baggage claim area of the next flight in…there it was.

Good plane, excellent food, crew and entertainment. Seats in business could use an upgrade

We departed late but made up most of the time in flight. Our ticket was pure economy, so it wasn’t anything fancy; however, I heard that we arrived in Madrid at the exact same time that First Class passengers arrived! Overall, our experience was similar to what we had on other American Airlines transatlantic flights - good value at a reasonable price. We were even able to get our carry-on baggage onto the plane without needing to gate check it.

It was fortunate that the flight arrived in London in accordance with schedule, and the luggage was promptly transferred to the luggage carousel. However, I find it concerning that even minor issues in economy cabins are prevalent within the industry. American Airlines, in particular, appears to have the least legroom and feels more crowded due to the proximity of neighboring passengers. Additionally, the crew’s adherence to protocol is inconsistent. While they may enforce certain rules set by the FAA on a select few individuals, they often overlook numerous violations, such as failing to reset seat recline during landing.

Easy and organized getting in and out of the flight

This review if for American Airlines. From London to LA, British Airways customers flew American Airlines and there was a small incident on the plane with a customer that was sitting next to me. She had a gluten free meal which she selected online. The flight attendant brought her food and both times, it contained gluten (bread, cracker) and by the second time, the customer mentioned about the issue to the flight attendant because she is highly allergic to gluten. Customer was very gentle and just wanted to note that both her meals contained gluten on the tray. The whole situation could have ended really well if flight attendant just apologized and mentioned she would relay the message to the responsible party. Instead, she entered defensive mode and started making some BS excuse about how the cracker that was supposed to be mine, fell onto her tray instead. Mind me, I already had that cracker on my tray. I doubt I would be given two. Also, she mentioned that the bread from the previous meal was gluten free. REALLY? I ate that bread and it tasted like it had PLENTY of gluten. The whole situation was handled so poorly, not only by that one flight attendant, but by 2 others. The reason I intervened is because the customer sitting next to me was tearing and all she did was mention the mistake which could have cause her health great damage, and instead she received attacks and excuses. AA, you should train your employees how to better handle situations like this. A 'well, I don't see why this problem is a big deal since you (the customer with allergies) read the ingredients and avoided eating the cracker that "accidentally fell" from the tray of the customer sitting next to you,' should not have been coming out of a flight attendant's mouth.

Continue to be disappointed that the “food” for “ordinary” fare paying passengers is poor - on this flight it consisted of a packet of two biscuits and a small bottle of water … not even offered a “free” cup of tea or coffee. Suggest a review of the “menu” and offer a hot drink to ordinary (economy class) passengers. On this route there are many far cheaper flights available - paying almost £200 for a flight that could have been bought for less than half this price should have some “perks” - offering hot drinks to all passengers would, in my opinion, be a cost effective measure which would improve the image of British Airways.

Aircraft was comfortable even in economy, clean. Entertainment screens were excellent and. Hoice was very good. Good was just ok. Crew was not bad.

Entertainment system didn't work well. Also no new movies and limited choice of other programmes. . And only one USB A charger option. Most modern electronic items needs USB C. Planes should offer both

I was unable to board the flight because I was unable to acquire a visa , Brexit changed my ability to get an ETA, I’m a Trinidad citizen and it takes weeks to get a visa

The issue was not with BA it was with the link yoiu sent fopr booking the flight

The space in the seat was okay, the staff were friendly, the entertainment system, my touch screen was not working and some of the films listed on the website for the flight were not available.

BA flight from London NY had old BC configuration with 2+3+2 seating with open seats which was not comfortable and lacked privacy

Flew business- but plane was dirty, food horrendous. Too many business class seats diluted service levels overall.

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices
