I have a trip booked BNE-SIN-LHR. I have requested a point upgrade for SIN-LHR leg, and I am wondering if it affects my chance of getting the points upgrade since I will be checked in all the way through to LHR (and hence I will have already checked in for SIN-LHR leg before the 5-hour cut-off).
Could anyone who can shed light on this?
