I don't know who you have been talking to, but you sure have a misunderstanding of how jobs work in aviation. First officer on a Global Express as an entry level job? And then leaving that for the airlines? Crazy. A Global Express job is a career position, and going from that to be a first officer on a regional would be a huge step backwards. I am a captain on a light jet, and have 4500 hours total time. If someone offered me the right seat on a Global Express, I would not hesitate, and it would likely mean a pay raise as well.
