Your choice - over LAX or maybe KUL?
If (big if) that was to happen, surely KUL any day. From a simple SLF perspective, wonderful airport with its own internal rainforest! For practicalities, not TSA processing just to transit - doh!
For yield, KUL is a key Asian city in its own right + connections if MH joining one world. IIRC, doing the Kangaroo that way at present on MH involves around a 7 hour layover (not such a bad thing considering above!).
Noting BA have gone into ICN over any new Chinese cities, sniffing the higher incomes there.
