Corporate flying were you live is great, but will the company exsist with a flight department in the next 20-25 years? Doubtful. At 35, I would go to UPS. You'll be a senior FO or Captain by 45. And have another 15 to 20 years ahead of you. You will be paid good coin, and not have to worry about your pension. And there is also a good bit of day flying.
