MCS? also note that there is a 1 stop (BKK) single flight number service from HKG-BKK-SIN (which I am doing later this year, CX713) which will give you 3 extra hours of F bliss on CX

This will only count as one segment on your AONE.
Assuming of course you are as mad as I am and this sort of thing interests you
Ditto with a 1 stop NRT-TPE-HKG single flight number (CX451).
