I agree with flyerjosh, there's no real formula. To me it's luck of the draw, I just finished my eighth year with my employer. This last downturn was particularly brutal on corporate aviation, guys with a ton of tenure at top shelf flight departments found themselves on the street. My department grew from 1 to 3 airplanes over 5 years and, while I never get too comfortable in any situation, I just don't see our operation ever going away. I do agree that the affiliated industry does play a role but even then, there's no panacea.
