Registered Nursing degree
Well, I have to chime in here. I've been flying for 20 years, but only the last four have been professionally. I've towed banners, flown corporate charters, and flown freight in DC3s. I've been furloughed or laid off three times, and every time I have been able to fall back on my degree in Registered Nursing. Darn tough degree program, but it's portable. I can work in any town, large or small, and my specialty is ER/Trauma.
I guess I'm hard-headed, but every time I get a $20K/year flying gig, I give up a $45K-$50K nursing gig and go fly awhile. I get furloughed and go back to an ER, and I work a few shifts in an ER wherever I'm based, so I don't lose my skills. However, if I ever land a career flying gig, I'll give up the ER in a heartbeat.
Besides, my favorite parts about being a male RN is that 95% of my coworkers are female, it never rains, and the nurses have their own degrees, make good money and like to go on flying dates. Not a bad gig.
