US Airways Dividend Miles Gets the SPG Bonus

 Your total = 30,000 Dividend Miles (for every 20,000 Starpoints you convert)

Again, this may only work for you if a) you have a bundle of SPG points sitting around and b) if you have a specific award in mind.

Note that US Airways does not allow one way awards, however, there are still some partnerships with Star Alliance partners Singapore Airlines and Turkish Airlines. Award bookings for those two carriers will be allowed through the end of this month (July 31st, 2014).

With Starwood, you  can transfer up to 79,999 Starpoints in a 24 hour period to an airline. In order to maximize the bonus, the best strategy would be to limit your transfer to 60K points a day in order to receive 90K US Airways miles.

And for every 20,000 Starpoints transferred within the same transaction, you will earn 5,000 bonus Starpoints which will be automatically added to your transfer up to a maximum of 94,999 miles per eligible transfer.

There is no minimum Starpoint transfer requirement for Platinum Preferred Guest members. Gold Preferred Guest members have a minimum transfer requirement of 1,500 Starpoints, and Preferred Guest members have a minimum transfer requirement of 2,500 Starpoints.

Transfer maximums are based on a combination of member Starpoints and the Starwood Preferred Guest airline transfer transaction bonus. Only one airline transfer transaction per member per 24 hour period is allowed; multiple transfer transactions within the same 24 hour period will reject. Both the Starwood Preferred Guest and Dividend Miles account must have identical member names in order to complete this request; different names will cause the transfer to reject. Airline transfers are one-way, non-reversible, and non-refundable.
