Great flight. I didn't watch the entertainment. I used my iPad the whole flight. But, staff was great, smooth flight, comfortable seat (business seat 7A) and food was really good (I'm a vegetarian).

Great flight. I didn't watch the entertainment. I used my iPad the whole flight. But, staff was great, smooth flight, comfortable seat (business seat 7A) and food was really good (I'm a vegetarian).

The flight was very nice but the food selection for the people in the last rows was limited to vegetarian meals only. I think vegetarian meal should not be offered as a main selection.

Really BAD check in experience. My bag was left in Geneva and I have not received it yet. I have been in Stockholm 5 days without clothes to change. The flight was good but very unhappy with the post service support.

We still don't have our luggages... flight was Saturday Jan 3rd and today is Wed 7th...even after fling the delayed/missing baggage report on saturday night and contacting SWISS (which is not answering) we still dont have our luggages...

Drinking water could be in more sustainable packaging than plastic bottles

They lost my luggage on December 30th. It is now January 3rd and i still don’t have it. I’ve called lost and found multiple times and they cannot provide an update. They keep saying one day and then it gets postponed again. This is ridiculous and unprofessional. It’s infringing on my vacation. I have stressed how important it is for me to have my suitcase right away. It should have been resolved within 1-2 days.

Made us gate check carry ons Then didn’t get them on the plane. Service they used didn’t deliver our carry ons for more than a day Total mess

0lane 2qs on tim3. Very bad food. No free wifi, only for texts. Entertainment poor and hard to access.

At boarding, the locations where we had to have our passports checked prior to boarding were very unclear. Occasional staff wandered around telling people, but in busy area of the terminal this was not obvious. It was also located well after the check in desk in terms of walking to the gate. The Premium Economy service was attentive and warm. The only big draw back was lack of restrooms, and no division or even curtain between PE and Economy.

We had seats between the bathroom and a screaming baby, and did not have enough room to lay my head down on the tray table. Not ideal.

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
