I've secured MEL-SIN-DXB-LHR F Reward seat for June next year. First 2 legs on EK, with a 9 hour stop over in Dubai before heading to London with BA. It's a Qantas issued ticket with one PNR. I've tried to look on the net/websites - I can't tell if my luggage would be checked all the way through to London in Melbourne, or if I would have to pick it up in Dubai as EK and BA don't seem to have a current interline agreement. The Qantas website, to me, looks open to interpretation. Any guidance or help would be appreciated.
