Hi All, I would love some guidance for an iterinary with a mix of cash/avios so it is all on one PNR
route: Cork-LHR-FCO return
Cork-LHR Cash
LHR-FCO avios

1. do I book Cork-LHR first and ring BA will they add LHR-FCO segment to the booking?
2. Should I book each segment separately and will BA link them/make them one booking/ticket?
3. If 1 or 2 not possible and I end up with two separate bookings will BA allow me to check bags through to final destination or will I end up collecting bags in LHR to recheck (this will affect the onward flight time I choose)?
