Have you ever thought about becoming an airline dispatcher? I'm not exactly sure about what they do, but I know that they do the weight and balance, weather briefings, filing of flight plans, etc. for the airline flights going out. Seems like that might be right up your alley.
Here's some other ideas:
Airline Customer service (just kidding)
LPGA touring proffesional
And I can't think of anymore...
PS, I'm also 25, and I love Eastern Airplanes. My first model I ever made was an Aloha 737, but the second was an Eastern L-1011.
