Experience and education in aviation don't have the value they have in other industries. If they did cadetships wouldn't exist. Big jets overseas is often a oneway ticket. Your friends best chance would be to target a second tier operator for a DEC.
VARA, Alliance, Network, NJS and JetGo to name a few.
Better off becoming financially secure overseas and moving back for an early retirement.
The upside is that they saw the world, flew big jets for big airlines. Something to be proud of no doubt.
