I have 3700 biz extra points and 2100 are expiring Dec 2012 --

what's the best redemption for this? Thinking Admirals Club membership -- do I have enough for a month or a year? Or can I simply buy 8 day passes at 300 miles each?

--

also my wife has 675 points expiring -- should 2 admirals day passes be best spend?

lastly, are the admirals passes electronic in your account or mailed to you in your name? are they transferable between spouses?

Thanks in advance!
