Do you have a Mileage Plan account? Do you have any miles accumulated? If you have 15K, you can redeem the AS50 award, which will allow you to purchase any ticket for 50% of the regular fare. If you have only 5K, you can purchase up to 10K in "Instant Miles" from Alaska. Actually, someone else can also buy up to 10K miles "Gift Miles" for you, but I am not sure how quickly that can happen.
