This one is a bit complicated but it is possible to get a domestic award ticket for 2,500 miles. You can use Starwood Points to redeem for this on a 1:1 basis too.
It involves some patience and last minute booking, but if you are flexible on your travel plans, this could work.
It is on Jet Airways, which is a new transfer partner of Starwood.
