...And if the truth will make you lose 120,000 think up a good story to tell them.

In all honesty just reading this sounds like you are some mileage broker, or some kind of person who wants to book for others.

Whatever the case may be, call MileagePlan and tell them what you have posted and why you did what you did and how you’re not trying to do any fraud and you’re very sorry for the confusion. Just don’t admit to breaking any rules that will get your account seized if you want to keep your balance. Alaska seems to be getting very serious about their security of MileagePlan accounts and fraud.
