Attaining Silver Status:
This 2nd tier status is attained with Qualifying Miles, the miles earned with THAI and Star Alliance airlines, during 2 rolling month periods, 10,000 Qualifying miles during a 12 month period, or 15,000 Qualifying miles during a 24 month period. This is a system automated process whereby on the most recent activity all eligible flights are evaluated for the past 12 and 24 month periods. With each new activity, status is again evaluated during the past 12 and 24 months, ensuring that all eligible flights are counted for attaining Silver status.
Retaining Silver Status:
Evaluations for retaining Silver status are on a personal calendar year based on the validity of your Silver status, On the date which current Silver validity commences, eligible flights are evaluated for the following 12 month period to ascertain if the 10,000 Qualifying Miles threshold is achieved. The same process is done during the entire 24 month period of Silver status validity in which 15,000 Qualifying Miles must be earned.
