It’s certainly possible, but probably unlikely. Not because of flying skills as much as all the attendant stuff—dealing with your own dispatching, handling bills at FBOs, making arrangements, and just learning how the operator operates. It’s not rocket science, but just like at your airline there is lots of procedures and customs to adopt.
Likely harder to go direct into an international operation from regionals—several more layers of stuff. And you will need good contacts. Pilots with good corporate contacts have a huge advantage, get the really good gigs effortlessly.
