"The grass is always greener over the septic tank"
Are you really upset that you didn't make the show? As an active corporate pilot, you have cracked the code. Your next job is out there as you network with the other pilots. Are the majors really better for you? As a junior pilot, you are at the most volatile section of the seniority list. Learning from the past, you could languish at the bottom for years. Is that more of less stable than your current situation?
As someone else said, you can run spread sheets all you want, but it will be based on a guess. Maybe I'll make captain in 5 years, but it might be 15. How does a furlough fit in? I can go on and on. It's a gut level decision that only you can make. I had a friend take the call back at United, leaving a DC-10 captain slot, only to be furloughed again. He died while on furlough. For him, he had no regrets. He wanted to work for someone everyone knew. There are no guarantees in life. All of us will only know how we did in out careers when we block in for the final time and look back. Until then, everything is a crap shoot.
