Non current guys have gotten called. Pk unknown.
Improve your odds - get a 121 regional FO job. Type rating, 121 experience, larger a/c experience, FMC/LNAV/VNAV/RNAV/RNAV(RNP) exposure, flight currency, etc. All good points.
Separating mil guy I know did exactly that - got hired by a regional and put that down on his on line app... and SW called. Got his type rating/IOE/LOE sign off and AA called. Started flying the line and DL called. Super competitive guy regardless but we'll never know if going 121 FO accelerated the process.
