Getting diamond
 

It looks like I will get to DIAMOND by april end. My membership year should expire 09/30; What happens now? It will reset starting april? Or it will go to september? I was going to book SIA EWR-BKK but eventually I decided to stick with Cathay, the last 4 Flights have been wonderful and I really felt spoiled. THANK YOU

When you reach higher level, your club miles count resets to zero.
If you reach 120,000 miles at mid-April, your new membership period is
30APR2009.
In this case, you have 12 months and a few weeks to accumlate 120,000 miles for diamond renewal. (e.g. 20APR2008 to 30APR2009, based on date of mile credit).
