Hopefully you've made your GI bill transferable to your dependents, as *that* is the best use of it in the big picture.
There's really nothing in terms of type ratings or other aviation qualifications (since you apparently already have your ATP and CFI/II/MEI) that is going to tangibly help you make the leap to career destination airline faster.
Theoretically, you could get a Masters with it, but I don't think that really adds enough value to be worth the money spent (especially compared to what that will be worth to send your kids through college).
