Transferred money to TDameritrade last week. Points posted in spg account today. No condition to keep money in brokerage account. It is 1 week only. Now can withdraw it to wherever you want. $75k earned for 1 week 60k starwood points. Definitely better deal than bankdirect. However 1 time only, not recurring. Any suggestion for best airline miles value for converting 60k star wood points?
