It would surprise me very much if many ex-C3ers were interested in a gig with JGO or any of the other LCCs for that matter.
Most are likely overseas getting a descent salary unless they lack ambition or somehow actually believe that this is the best country in the world to be in for pilot employment.
Based on the number of pilots I know in this country, most of the 'experience' has left the country for greener pastures.
But, you never know.
