We could do it beesflyer, but it is cheaper for BA to pay cleaners on the ground to do it. You seem to be forgetting that BA offers a full service product, not a charter one. I can assure you that BA crew are very busy on board now that we have new crewing levels. Let me repeat that BA crew begin collecting rubbish right after the first bar round and then through out the flight.
So who would you travel if you had a choice between Thomas Cook and BA on the same day on the same route at the same time?
