Why not just transfer the miles w/in AS program?
Transfer Miles
While you can always redeem a full award out of your own account for a friend or family member, there may be times where you just want to move miles from your account into theirs. Our Transfer Miles program allows you to take miles from your Alaska Airlines Mileage Plan™ account and transfer them into the Alaska Airlines Mileage Plan account of a friend or family member.
Transfer up to 30,000 Mileage Plan Miles in increments of 1,000. Transfers in or out are limited to 100,000 Miles per calendar year, per account.
