Something to consider is that you are well aware the airlines aren't exactly hiring off the chain right now. So, here is my take. In a few years (when you might meet the mins. I am just assuming that at this point) the airlines will probably be in a better scenario as far as growth and hiring. If you take one of these contractor jobs, it won't help you get a 121 job, but I wouldn't worry about that. You will have the flight time in a few years. Say you take a deployment and fly UAV's for 1 year. I am guessing that with around 130-140K for a 1 year deployment you could pay off all of your debts. Then get into the 121 world just like everyone else did. There is something to say for a junior guy in the 121 world to be debt free. I was there. I did the 121 gig for 5 years. Now I am considering UAV deployment myself to wipe out all of my debts.

On the other hand, what kind of commitments do you have? Are you married? If you are a male and single I would say go for it. It's an adventure and an opportunity of a lifetime. You get to serve your country and you get a major step ahead in return.
