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

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.

I Keep your expectations to low to middling with BA, or most European/ US airlines these days.

Wish the food and overall service was better. They treat Business class passengers same as economy

Old plane, sold out on snacks, just trashy seats..broken..etc

Good flight. Only negative was the bus journey from plane to the terminal. Didn’t exit t this either BA at T5

Nothing! They canceled our flight to Greece the morning we were supposed to leave and offered us another one 5 days later (for a 9 day trip). They said it was an “operational decision”! Yeah a 777 that was 2/3rds empty, so they probably sent it to the Middle East to make a fortune getting people out of there!!

WiFi wasn’t available to economy until the end of the flight.

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.
