I'm trying to book SYD-DXB-LHR (with a stopover in DXB) with EK using QF points through the QF website, but it won't show me a DXB-LHR flight with EK. I can book SYD-DXB with EK but my only options for DXB-LHR are BA and Royal Jordanian. Does anyone know why DXB-LHR with EK doesn't show and is there a way to book the ticket I want using Qantas points? Any help much appreciated.
