easyJet also offer it, which is surprising given the complexity of their network (BA only loading catering in 4 locations for the entire shorthaul operation, easyJet load catering in 4 places in Scotland alone). I don't think it is that popular yet, but they do offer special online deals, since there won't be any wastage on this business. There again easyJet own their BoB process and it's a key money maker. BA's outsourced it, and so while it makes a bit of money, its key job was to remove ET catering costs entirely.
