Airline and Corporate are as different as chalk and cheese, but then so too are Corporate flying for a private owner when compared with a Charter Operator..
One man's private owner can be a dream to work for, while another can be an
hole, and similarly charter operators range from very good employers to outright thieves, cheats and cowboys.
My advise would be to stay where you are until you find a job in corporate that you have thoroughly checked out, vetted and are sure is an outfit you certainly want to join.
