I am starting to be quite amazed that BA haven't the ability or improvisational skills to sort something out especially at out stations after all this time. There should be food on incoming flights at the very least. As for outgoing - even refridgerated truckloads of Pret-a-Manger or Marks and Sparks sandwiches, fresh fruit, crisps and salads could be organized along with improvised delivery to flights. Supply dry ice to the trolleys.
