Is this a nesting problem?
Planing on flying to HBA (Tasmania) and it looks like buying four separate tickets is the best way to get it done. Would this cause any issues with AA when I check luggage in at RDU all the way through to HBA?
Ticket #1: AA (RDU-LHR, LHR-ORD-PHL)
Ticket #2: QF (LHR-MEL r/t)
Ticket #3: QF (MEL-HBA)
Ticket #4: QF (HBA-MEL)
