Honestly a year or 2 at a regional (they all have diff pros and cons) to check the 121 box will open some more doors. Also realize ACMI classes are filled from large Pilot applicant pools. Etc…I may take heat rounds for this but apply at Breeze also. That could be a blessing in disguise for someone with your background…movement, jets, 121, king air moonlighting etc…might open some doors. Realize in this biz 1 step back to take 5 fwd is sometimes required even if not preferred. All the best.
