tl;dr

Annual statuses:
50,000 FOPs for Sapphire (OWS), 80,000 FOPs for Premier (OWE)
Assuming you are earning FOPs from say discounted Business LAX-HND, that's roughly 6 and 10 round-trips, respectively.

JGC status 2024 and after:
You need 300,000 sector miles
That's roughly 28 LAX-HND round-trips.

(Or you can slog HK$3.6 million on Aeon Card JAL. I mean slog, trying to perform a one-shot MS might get Aeon HK to canx you for AML or some other trumped-up offence)
