SPG.com site says:
With US Airways®, you can transfer up to 79,999 of your Starpoints® into Dividend Miles® at a 1-to-1 ratio. 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.
Does that 94,999 miles apply with this promotion if I transfer 60K? Do I need to make 2 seperate transactions?
