GA companies it is not different.
It can be different, you just need to find the right company, have a look at websites (cant name them) for Learjet positions that may take you out from your own country, you might find that you enjoy it.
Unfortunately you dont have the experience for airlines such as Emirates and Qatar, nor do you have the hours for DEC, so you are left seeking a right seat, thanks to the "wonderful" world of P2F, you are fighting against people who are generally younger than you and are willing to pay a stupid amount of money to pursue "their dream"....
Good Luck.
