The worst experience with British airways that left me with a delayed flight until the next day and no hotel accommodations available or food voucher. I still have had anyone follow up on this matter

The worst experience with British airways that left me with a delayed flight until the next day and no hotel accommodations available or food voucher. I still have had anyone follow up on this matter

Always the same, boarding starts before the plane is ready so we were all standing in the sun and 36 degree heat on the tarmac. Once in London, packed like sardines in busses to the terminal. BA have a way of making you feel like they dont want you as a customer.

We boarded late, sat on the plane for 45 minutes, I was sweating on the plane and there was a child that screamed and kicked my seat almost the entire flight. The parent nor the crew would do anything about it. Food was very good.

The crew member of my cabin was excellent. The flight was delayed due to air traffic in London. I worried about my connection. The flight attendant eased my worry with prompt updates on the current flight status, as well as helping me log on to BA.com to find out the exact gate info for the next flight. Truly appreciated his help.

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.

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!

Plane is old. Toilet did not work. Once in Singapore the continuation to London was cancelled.

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).

In the "old" configuration Club class, in an aisle seat you are literally sleeping in the aisle with no privacy at all. In addition, there is hardly any storage space, and it is hard to make sense of the seat controls.

Everything was excellent, although flight delayed however can’t control that, but what I don’t understand is why the smallest portion of food ie: bit of rice & bit of chicken (no exaggeration) no salad, no veges, nothing else, but cake & icecream later…this is just not a great reflection on the quality of airlines. People spend $1,500 on a flight surely airlines can spend an extra $1 on their passengers meals…even bread & butter can do the trick. ESP on a 8 hour flight! Cutting costs is one thing, but this is just not ok.
