All good, professional service, and arrived close to on time.

It's hard to tell where to plug in electronics, and the port on my seat didn't work. Their entertainment system was down. Vegetarian food options were tasty. Friendly, helpful flight attendants.

We loved our flight attendant (Emma, from Scotland), the meals were perfectly spaced out, and the in-flight entertainment was super generous and delightful.

Cancelled flight and re booked seats were a downgrade. British Airways said the upgrade was t available but when I checked it was but then they wouldn’t make it right

Flight attendants need to come by a little more often to pick up trash.

No WiFi. No food. 250 ml of water only drink option. No entertainment options. Extremely bare bones flight

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

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

The check-in baggage belt was broken (which is understandable) but what was surprising is they would check you in, give a baggage tag and then you have to drag the baggage to a different counter at the end of airport. No vegetarian option in in-flight meal. British Airways remains the worst big name airlines and always my last option while booking.

The to flight was excellent but the return flight the seats seemed not cushioning enough.
