Indy,
My humble advice is drop the $75 now and get in the system. That's one good round at the bar on a Friday. You can continue to update as you get your reqs done. Once the window closes...no soup for you until it opens again. However, you can still update your junk. We have had hiring without reopening the window. Not sure if you are talking 2, 4 or 6 years out but it isn't gonna hurt. If the airlines is what you want, take a long weekend and get the ATP done ASAP. No excuses to not have it. As far as the FE written, well it only makes sense to wait a bit on it. Your bone(so to speak) might not have a type associated with it but it will still be pic jet time. Good luck and pitch into the fight.
