I thought this could be such a good deal I had to post it.  From May 1st through May 31st US Airways members who register here then transfer hotel points to their Dividend account will get a 75% bonus*.  I placed an asterisk here for a reason, the promotion is not what it seems, there are different bonuses based on what category you are in.  So this promotion is definitely your miles may vary (YMMV).

Back in 2009 I transferred hotel points to US Airways (when there was no bonus) to book a trip on Lufthansa’s first class product.
