I've got two oneway tickets:

One:
LGW-DXB (EK2) DXB-CMB-SIN (EK348)

The other:
CMB-SIN (EK348) SIN-MEL (QF)

The overlap is

I.e. I'm on EK348 CMB-SIN on two different PNRs (one in Y and one in C).

Would EK in London be okay checking my bags through to MEL?

Otherwise I'm thinking the best way is just to check bags at LHR through to SIN, get the 2nd CMB-SIN BP at the CMB transfer desk and once in SIN collect the bags and recheck them...

Can anyone see a problem with either option?
