So back to the original post....Is there a date that I need to take my annual retreat by for the $750 airfare credit? Thought I read online by March 31st 2015?

I'm still a little confused and this still doesn't seem to be entirely clear. Please tell me if this is right or wrong...

My Diamond Status will be good through March 31st, 2016.
My Diamond Aspiration 2 Status is only good through March 31st, 2015.

Meaning my Diamond Companion Card is only valid through March 31st, 2015
-and-
My $750 Airfare credit must be used by March 31st, 2015
