Consider what you could do part time:
Crop dusting ( dying art form)
Glider towing
Para dropping
Sight seeing flights (seasonal)
Banner towing (seasonal)
Flight instruction
Air Show flying (sponsored)
None of these will pay enough to rub two nickels together. You’re talking pretty much hobby level flying with expenses paid.
Not to mention the competition for these jobs.
As an example you’re looking for a new pilot….who do you choose…who does your insurance company like best…the 300hr CPL or the retired airline pilot with 15-20,000hrs?
This is not an easy industry
