For the SCB 100k Asia Miles welcome offer (now changed to 30k Asia Miles), we hit the $177,500 within the first statement cycle. I just checked the statement and only 42k Asia Miles are credited to the account this month -- will the 'bonus portion' (however much that may be -- I'm not sure how they segment the miles) be credited at a later stage or in the next statement? I can't find the T&Cs for the previous welcome offer so can't double-check.
Most of the spend was overseas so the ~42k miles seem to be at the 'standard' HKD4 = 1 Asia Mile overseas earn rate.
