BF,
I love FedEx, and it was the right (albeit) tough call for me back in 2002.
You, on the other hand, have an ID in hand and a year on the property at a growing company where you are happy. I think you made a solid choice, and I wish you the very best.
You may just look like a genius in ten years. If in 10 years JB has gone belly up, you'll have still had fun on the way, made some decent money, and will likely have 5000-10000 PIC turbine hours. You'll find another job. Plenty of USAir and TWA guys can tell you how to start over at 45. Don't live paycheck to paycheck and you'll be fine in any outcome. Hopefully your biggest choice will be whether to retire at 45, 50, or 55.
In any case--thanks for sharing your choice and good luck!
