Funny. Pre-COVID, during the “pilot shortage”, I watched a few older GA guys try to make a run at the airline gig. They’d all made their nut lawyering, selling, trading or whatever, had a couple thousand hours in their Cherokee or Baron. Kids were out of the house and the wife was tired of their retirement plan.

They all quit after a few months at the regionals. Turns out it wasn’t what they expected. Some didn’t make it through training. These were guys who had some awareness of flying, but not the ancillary BS that makes up 95% of the job. Apparently a professional dude that has spent some time in the world doesn’t have a lot of tolerance with getting jerked around by the high-school graduate working in scheduling.
