Nice aircraft. Good crew. Delayed departure from Houston, but arrived on time in London. Main thing I don’t like about flying BA is having to transit through security in London Heathrow. A major pain!

Nice aircraft. Good crew. Delayed departure from Houston, but arrived on time in London. Main thing I don’t like about flying BA is having to transit through security in London Heathrow. A major pain!

Was upgraded to business class on this flight, I presume due to my premium economy class for my London to Denver flight. Business class was the same seats as economy, only the middle seat was unfilled. Decent lunch served, and the lounge experience in Prague was good. The only heads up I would give is give yourself enough time for gate carry-on luggage scanning, which I did not anticipate in my time planning.

Overall good, bigger chairs in the future would be nice.

I loved the food choices and the attentiveness of the crew but boarding was chaotic.

Great flight, last one out the air-conditioning was far to hot and the return it was to cold and then issued blankets. On the outward bowned the headset connector didn't work properly. You had intermittent sound from the audio socket.

My experience with British Airways was fine and dandy. Nothing truly negative to report. However, I was. asked to check my carryon bag all the way through to my desitination which prompted some huge problems. Thank goodness I kept a foldable-personal-item-bag in my carryon. I was asked to remove my valuable electronic belongings from my personal item bag, which was a camera bag full of expensive lenses and camera equipment, into another bag for the flight because it was "too big". Farbeit from me for asking further questions, but the bag was let through when I departed to Paris from America with no problems at all as I was able to explain that it was slightly oversized due to being a camera bag with a layer of protective foam which made it slightly larger. Still, this bag could and did fit perfectly under my airplain seat during my departure from America. On the flight back though, this was not the case and I was asked to remove highly valuable personal items, stow my camera bag in my checked bag, and then had to pay and overweight fee. Kinda bogus, but I was tired and wanted to get home so I complied. Regardless, it would have been nice to have had my bag retrieved during the London to Pittsburgh flight so I could put on new clothes and freshen up before take off.

The staff was extremely friendly and nice. Overall, the flight was pleasant, and the food was good. They asked me to check in my smaller cabin luggage suitcase in Mumbai as the flight was full. Fortunately, I had packed a spare set of clothes in my laptop bag so I was okay.

Flight was delayed by over two hours and that meant my connecting flight was in jeopardy but there was no acknowledgement or help from the BA staff

The gate agent made me check my carry-on in Denver, even though I've traveled all over taking this case on the plane. Beware folks. Food in Premium Economy was quite good - excellent blanket! Flight attendants on the Heathrow-to-Budapest flight on 3-27-2026 were quite snappy. I got a frown when asked to unscrew the water bottle cap for me (I had a cast on my right arm). Also woke up right when they were handing out biscuits. She had given my rowmates one and was in the process of giving water when I asked for a biscuit. She scolded me and said, "You snooze, you lose". She did give me one, but I thought that comment was uncalled for.

Business class on British Air with the Airbus 320 means the same seating as main cabin ( 3 - 3), but with the middle seat of each three-seat row blocked off to become a platform/table. This is decidedly NOT a business class experience. Other aspects of the flight were fine.
