I hear that the machines are now much more reliable. I have heard of silly loading however such as two sandwiches loaded for a CPH flight. I think it will take a while for them to get reliable sales data and be able to load the correct number of fresh options. If it like most airlines BA will pay for sandwiches loaded and not necessarily sold. It's not feasible to load 300 sandwiches on the off chance that you'll sell them all but at the same time 2 for a business flight isn't good but I'd be telling porkies if I said it never happened in my outfit.
