Hi - I am looking to book a return flight to London from Sydney and have a heap of points. Nothing comes up for the dates that I am after when I search for a return flight but after a lot of navigating, I can book this as a multi city - Sydney - Singapore, Singapore - London, London - Sydney. The way there is on the same day and has a three hour layover in Singapore, so it essentially is the connecting flight I just have to book as multi-city - will I be ok to get my luggage to connect through? Another point, it is economy to Singapore and then business to London. I am a Gold QFF so, my luggage goes through as Business either way.... I suspect it should be ok but a self transfer in three hours at Singapore airport would be tight.
