Heathrow
Aircraft 1 - Heathrow - Bombay
Daily LHR BOM A330 (Dept 09:35)
Aircraft 2 - Heathrow - Riyadh
3 Weekly (247) LHR RUH A330 (amazingly also departs at 09:35)
Well, knowing BD, that suggests they're facing a choice of which way to operate a two stop service...
LHR -> BOM -> RUH or LHR -> RUH -> BOM
