No cost per lead benchmark for flight training has ever been published. The closest proxy we can defend is Google's Education and Instruction category, from 13,474 US campaigns between April 2025 and March 2026. That category blends tutoring with online courses. So treat it as a ceiling to plan against, not a number to expect.
Run the arithmetic at both ends. A $4.81 click at a 13.14% conversion rate is about $37 per lead. A $6.23 click at 11.38% is about $55. Push it to an aviation head-term bid of $7.39 at a more cautious 8% and you get about $92.
So a lead costs somewhere between $37 and $92 in media. Google's own guidance is that a bid strategy needs at least 30 conversions in 30 days before anyone can judge it. That puts the floor near $1,100 to $2,800 a month in Google Search alone. It is why we suggest starting at $3,000 across channels, and why a $500 test proves nothing except that $500 was not enough.
Further down the chain there is a check worth having. Two public career-education companies report both their advertising spend and their new student starts each year. Across FY2023 to FY2025 that works out to $2,310 to $3,193 of media per new student start, over roughly 50,700 starts. It is a proxy from trade and technical schools, not flight training, and it counts media only. It is also audited, which is more than any figure a competitor will quote you.
Everything above is a proxy. Here is one number with our name on it. At Hawkins Flight Academy we spent $7,668 on media between July and December 2025, plus $9,000 in fees, and produced 348 trackable leads. That works out to $47.90 per lead with the retainer included. Almost nobody publishes a cost per lead that has the agency fee inside it, which is exactly why we do.
How PPC works for flight schools walks the rest of the chain, from cost per lead through to cost per enrollment. Right Rudder Marketing is a flight school marketing agency, and the retainer in the Hawkins number is what that costs.
