I thought the 0720 slot might have been used by GB, but according to BA timetable, it isn't.
When I looked at bookings for MAN and BHX to FCO for next summer, both are showing as having flights on Mon, Thurs and Sats. Flights come up as daily on the timetable though.
Maybe when BA say that they've suspended these routes, they intend to bring back seasonal service....?
