In the advent of flight school partnerships and industry sponsorship, students are being headhunted straight out of class into profitable roles in commercial airlines. Without the need to put in the standard 1500 hours of airtime often achieved by becoming a CFI, there’s currently a rather drastic shortage of PPL instructors.
You’d assume that offering more money would make becoming a PPL CFI at least for a while more of an enticing prospect, but wages remain at the same level, which is around 25 - 35K.
The truth is that the wage of any sort of flight instruction is subject to the whims of the weather, location, flight hours, and the success of the school that employs you, so you can expect to earn the same amount as a standard CFI.
The fact that your students wish to be able to run a small, private airplane as opposed to students who want a career as a pilot flying large commercial aircraft, doesn’t necessarily mean you’ll get paid any more than usual. As a CFI, you may even end up splitting your airborne work hours between PPL and career path students.
