give yourself extra time to go through security

Pack your liquids and toiletries in plastic bags and be prepared to pull it all out. London Heathrow airport still does this, and makes you rescan through security between connecting flights even though you never leave their airport. If you think 2 hours between flights (time chosen by them not us) is enough, it’s barely enough if they fly into one terminal and depart connecting from another, so don’t plan to eat or drink anything in Heathrow.

Allow time for very long boarding process with busses and slow boarding procedure. If flying business class, try to get exit rows.

The crew member of my cabin was excellent. The flight was delayed due to air traffic in London. I worried about my connection. The flight attendant eased my worry with prompt updates on the current flight status, as well as helping me log on to BA.com to find out the exact gate info for the next flight. Truly appreciated his help.

The crew member of my cabin was excellent. The flight was delayed due to air traffic in London. I worried about my connection. The flight attendant eased my worry with prompt updates on the current flight status, as well as helping me log on to BA.com to find out the exact gate info for the next flight. Truly appreciated his help.

Significant delays on the return blamed on weather. Otherwise pleasant and helpful staff. Overcooked chicken on return limited options for dinner.

Our part of four was delayed both ways between San Diego and Pisa causing our family to be split up with three of us stuck in London overnight No compensation or upgrades were offed and we missed work as a result Food very poor and we declined two of the four meals offered I will affirmatively avoid flying British Airways from here on out

The crew was exceptionally good. Came around with snacks and drinks multiple times during the flight. I asked for hot water and they remembered. Responded to call light promptly. Very pleasant. The aircraft was also kept very clean. Boarding was organized. Overall was a great experience.

British Airays fails to enforce its own guidelines regarding carry on size limits. There were MANY passengers with full suitcases stuffing them into the overhead compartments leaving no space for others, like me, who adhere to the posted sizes. I had to put my carryone bag into my foot space, in additon to my carryon personal item, leaving me cramped for a seven hour flight. I was in physical pain, and I attribute this entirely to staff unwilling to enforce limits. The infotainment system was horrible. the touchscreens did dot work correctly, and there was no information on system operation. I am 77 years old, and a lifelong movie-goer. I recognized ONE movie (and not much better TV shows). It seems that BA saves royalty money by limiting its move and TV selection to absolute rubbish. The FlightAware program is the worst informationsystm I have ever seen, it is completely worthless. I pay attention to the safety briefings...in the event of an emergency, one is supposed to assume the "brace" position, except the seats are so close together, front to back, that it is not possible to assume the position without striking the seat in front of you. at age 77, and a lifelong traveler, this is the worst flight experience I have ever had, and I will never fly British Airways again

Boarding crew were extremely rude. At check in, I showed a medical note from a surgeon stating that I had a medical problem that caused me to end up in an emergency room. The surgeon requested that I get an upgrade so I can travel back home comfortably since I was in a lot of pain. I was alone with my daughters (9 and 14). They made a huge deal about giving me seats although there were so many empty seats in business. Finally, I paid a hefty price for it and the seats were exactly the same as in economy cabins but not as good because there was a forced tray in the middle seat that I couldnt even lift so I can lay down.

Delays on take off, delays at gate on landing, lugging lost to the ether. power on seats not working, couldn't work due to that and no WiFi. The crew was great and boarding was orderly if confused and rushed.

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.

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

Gate agents were late…flight was late and air attendants unhelpful.
