Instructing experience doesn't count at the airlines but turbine multi time does.
Lol, care to elaborate?
To the OP, I'd go find a VFR 135 gig and get some real experience, don't underestimate PIC time, no one every said they wish they had less command time and more SIC time.
Sounds like you got the hours to land a 135 VFR job, and the season is just starting for that type of flying, go live it up, you got a fun journey ahead of you if you let it be, go check out AK, or go to Africa, or just call around the VFR charter places, or if you want to instruct go try to get in with FSI.
Being a seat warmer in a lear, unless they are paying you a ungodly large amount of money for some reason, seems like one of the last things I'd recommend.
As far as sidestepping a regional, which I think is a currently VERY good idea, not sure just PICing a Lear would do it, you probably want to hit ATP mins then get a job fly a Boeing for one of those iffy cargo opsthink Calitta or atlas or something, and make Capt, and put your app in to fill in the blank major.
So yeah, of it were me, I'd go do a season or so in AK or Africa and have a adventure, get on with a large aircraft cargo op, apply for major.
Surprised you can get a SIC in a Lear at minimum hours. I know there a pilot shortage but that is a bit surprising to me.
People arnt lining up to SIC old learjets, I'm also guessing it's not a lifestyles of the rich and famous type QOL type job
