OK, thanks. I did not check and assumed that anything less than twice weekdaily would make little sense. Realistically, a twice daily flight with a single aircraft on a route with a block-time north of 2,5hours would not be that helpful either as the first arrival into FCO (or LCY if the aircraft were to be based there) would be around noon-time and unlike Alitalia, BA has nothing to do at FCO before a second daily flight in the afternoon.
