But in the old days of CX, you can still earn real miles while still getting the status miles towards Gold or Diamond membership, but the real miles that u earn are not with CX, but other airline FFP, such as the AC Aeroplan, Passages, BA Executive Club (not too sure).
Anyway, it was quite a good deal before, but now.......... better join CP and register with a non-Asian address for full mileage on discount economy.
