Mind you, you need to fly 30k every 12 months, so you can't say I flew 7000 miles in November 2012, flew 7000 miles in September 2012 and then you join in April 2013 and between April 2013-2014 only fly 16k and retroclaim the rest to gain status. I think I read one of your previous threads saying how you only fly once or twice every year, that's not going to cut it even with the YYZ-HKG route, you need to fly minimum of two RT every year in order to get Silver. Hope this helps!
