I am travelling:

AKL-SIN
SIN-LHR
LHR-SIN
SIN-AKL

How many PPS sectors do I get? Each of these flights equals 5 PPS sectors, I think. My calculation is that I get 20 PPS sectors.

They are all different flight numbers and on the e-ticket they appear on separate lines. I have a one night stopover in Singapore. Does this mean each leg is treated as an individual sector and not treated as a cumulative flight in which I would earn only 5 PPS sectors going out and 5 upon return?
