Nomoneynowek. Sorry, I must have dated myself quite a bit regarding Pinnacle. Don't know when they left Atlanta. They were owned by a 'gentleman'
named Michael Brady.
Years ago, while they were either Republic Express, (Phoenix Airline Services) along with Mesaba airlines, became a major part of Northwest Airlink, the headquarters was south of Atlanta Airport-even though the hubs were in other states. Even then in Atlanta, depending on the year, the only hubs were operated by Eastern Airlines, E. Metro, Delta and ASA.
It might be worth it to check Mesaba Airlines, but have no idea if Mesaba ever sponsored guys/gals from other countries.
We also have a Hungarian guy who years ago flew with COMAIR, a significant partner in the Delta system, along with ASA and Skywest. I've worked with him, a Swede and maybe two others.
