I'd stay in, but I wouldn't take the bonus... the freedom to punch out is a bigger opportunity cost than 25K, specially as an O-3/O-4 making livable money. I'm neither, and as a Reserve bum I can tell you that's the biggest achile's heel with you AD types, you can't downsize out of that govt cheese, even after all the soul-stealing chit you guys have to put up with for it. For a 10-year AD guy to NOT know the paycut taking an airline job entails is inexcusable. I recognize not all of us have the foresight to marry a rich girl (I used to scoff at that notion, now I just nod and keep my thoughts to myself), but to stare at the mortgage bill post-separation and first year FO pay with cluelessness is just your own doing. It sucks but it is what it is.
If you can snag a Guard/Reserve job that allows you to effectively bum, you'd should be making 65-85% of what AD makes, depending on how much AD MPA devil-selling you can/want to do. Plus, you'd be better positioned to fall less flat on your ass if you get furloughed right away.
Additionally, you could do the deed and take mil leave for the year and do the guard thing until you can hold the schedule in your base of choice/time of choice/ hours of choice, whatever it is that makes you tick. Try that on a 9-5 non-flying gig. As much as they talk about USERRA, I can tell you from experience, it's a pipedream, they're incompatible affairs.
Don't get me wrong, there are a lot of messed up things going on in the Guard/Reserves as of late, TFI is killing the Reserve way of life, and I'm not exactly on cloud nine with the shenanigans going on at my unit, but all things considered, it is about as good a backup to the idiocy we call the airline industry labor contentions as there is out there.
As to the poster who suggested not to worry about hiring waves, I guess I agree if the point that was trying to be made was that there's little point in trying to constantly preposition yourself to be at the beginning of a hiring wave. I agree with that. Success at the airline thing is in my generally limited experience, SOLELY a function of timing. No amount of people "you know" will overcome chitty timing, and certainly being a good stick will do exactly chit for you in a job whose descriptor demands you be a carbon copy of your peers, and competitors. But to dismiss the relative space in time in which you're hired as inconsequential is foolish. At my unit I've met them all from the regional dudes to the senior CA's living it up and min running the unit, some even with ungrateful contempt. The difference between them all wasn't attitude, nor who they knew (to an extent), it was cold cruel timing. Some of us will get lucky and ride a career down easy street, some of us will get knocked down early and often and will quit or never progress to where others did. In that respect, it is about par for the course with that thing we call LIFE.
It has been suggested before that it would be foolish to give a cursory look to the retirement figures post age 65 and assume it will be a one-for-one kind of attrition. As someone sitting on the fence, I have to agree. I think it would be foolish to stare at 2013 and think the floodgates will spread wide open. The airlines will contract some, or a lot, and there's plenty of people currently on the street, not to mention all those who are currently building their time and will be sitting on the fence ready to throw an application when 2013 does come around, to consider said timeline as dramatically positive for snagging a top line job. It will be better than today, but that doesn't say much about today or tomorrow, since what's the exponential of a number less than one right? The exponential of a turd is a smaller turd, but a turd nonetheless.
So in closing, I'd keep the AD cheese as long as possible, but I wouldn't take that bonus though. I'd seriously consider Palace Fronting in lieu of the former, and learning to live lean, since you'll be doing that anyways pursuing an airline job. Good luck brother. Nothing you can do but that'll carry you farther in this business than anything I've witnessed. I gotta pick up more drinking and less essay writing.....
