Meh. Lived the seat. The entertainment unit did not work and had to be reset 3 times. Service was SLOW taking over 90 min to be served. Crew forgot about my meal. Chicken was dry and almost inedible.

Meh. Lived the seat. The entertainment unit did not work and had to be reset 3 times. Service was SLOW taking over 90 min to be served. Crew forgot about my meal. Chicken was dry and almost inedible.

Disastrous. Creeping delays and cancelations. A routine 2-1/2 hour flight turned into a 12 hour nightmare and getting dumped at London Southend at 11pm instead of at London City. This required a £150 Uber ride to East London at 1am. We lost an entire day.

There was an older steward, he is top notch. He is very attentive at the passengers. I do not know his name. Thank you to him.

Good was great. Some of the older crew were grumpy and not customer friendly.

Everything about the flight is better,just to work on the food Everything about the food is very poor

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

This was a special trip so we booked first class. It was obviously an old plane as the seats weren't that comfortable or spacious. We were delayed 45mins taking off as the "little engine that starts the big engines doesn't work". The powered divider between myself and the next seat in first class didn't work and my electrically powdered seat didn't work so I had to move seats to try and get some sleep. Food and drink were good, crew were great. But I'll never fly with BA again.

Service and food was amazing. Aircraft configuration is weird - stare at a stranger at take off and landing, during flight someone is crawling over your seat. It was lame.

The plane was a long way from departure lounge. The plane looked tired but got us there.

BA Canceled this flight and put us on a flight leaving Aberdeen at 8:00 PM, delaying our return to the states by a full day. The cancellation caused us expenses in both Aberdeen and London and BA was completely unhelpful on the phone and at the airport.
