Boarding was orderly, pilot and flight attendants were nice, entertainment options were good, and low sodium meals were quite tasty.

Flight delayed, connection was not at gate listed and so missed, staff were rude at Heathrow, phone tree stupid and difficult, took me 21 actual hours to reach my destination. Almost lost my hotel reservation after walking in a strange city alone after midnight because they would not put me up in a hotel at sfo or heathrow. I will never fly BA again and will tell all people and Instagram followers never to fly BA.

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

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

The flight was very delayed in taking off - which was out of control of the crew, but then the pilot worked hard so we only arrived about 30 minutes late. Everyone was very friendly and accommodating!

Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?

Enjoyable flight, helpful crew everything was organized to accommodate passengers.

This was the second time on BA, food terrible, bathrooms gross,( granted, that was mostly due to the disgusting children urinating all over it)boarding was late and disorganized. No gate issued until last minute st Heathrow, bad system, caused undue stress. Seats were painful, that's what you get for traveling like a poor in economy, right BA? Should have been able to afford business or first class if you want to actually be able to walk upright without back pain after a trip.

Flight was canceled with little notice or explanation. There were no other flights to Belfast from Heathrow, so I had to travel across town to London City (or wait until the next day).
