Please note that both the Starwood Preferred Guest and the airline account must have identical member names in order to complete this request. Different names will cause the transfer to be rejected.

Note, however, that you can transfer points from one Starwood account to another Starwood account at the same address. For example, points could be tranferred from your account to your spouse's account, and spouse could then transfer to own Skymiles account.
