Those 8 sectors are at the end of a combined DONE3/DAS13. I’ll be away for 5 weeks. If I only had a carry on, I wouldn’t have mentioned having a bag at all. I’ll have a backpack, a laptop bag and a checked bag.

I thought that there would be little point in having BA load a bag onto a plane, take it off once it lands, only to put it back on the same plane 2 hours later. So minimise the chances of BA losing it, by not letting BA have it at all.

Any chances of getting Qantas to just keep it on QF30 though to Melbourne and I could just pick it up from baggage services when I get there the next day?

I guess the best idea would be:
- get AY to check the bag through to LHR
- pass through UK immigration to get landside
- put bag into storage in T3, transfer to T5 via train
- fly LHR-DXB-LHR
- transfer to T3, pick up bag
- check in with QF to NRT or SIN
- collect bag and recheck though to MEL
Would I have to go through immigration at either NRT or SIN to collect the bag, or just hand over the bag receipt at a transfer desk?
