The most common budget conversation in aviation marketing goes the same way: an operator shares what they spend, we ask what enquiries it produced, and the honest answer is "not sure." Not because operators are careless — because nobody handed them a baseline. This is that baseline: what aviation businesses typically spend, where it goes, and how to judge each line item.
The baseline ranges
Across the flight schools, charter operators, and maintenance businesses we work with, marketing spend clusters into three patterns:
Flight schools typically spend the equivalent of one to two discovery flights per enrolled student, per month, across Google Ads, SEO, and content. A school targeting twenty enrolments a quarter is usually spending in the low four figures monthly. The budget tracks the enrolment pipeline, not the calendar — schools that spend the same amount in September and January are either overpaying in one or starving the other.
Part 135 charter operators spend less often but heavier per enquiry. A corporate contract is worth multiples of a leisure charter, so the spend concentrates on being found for the specific trips they want — regional keywords, aircraft-type searches, broker-alternative positioning. Monthly spend in the mid four figures is common where the operator is serious about direct bookings.
MROs and FBOs are the most uneven group. Some spend almost nothing and live on OEM authorisations and word of mouth; others treat capability pages, AOG visibility, and parts-distribution search presence as a standing budget line. The ones spending deliberately usually tie it to specific maintenance revenue: airframe capabilities they want more of, engine programmes they can staff for.
None of these are audited industry statistics — they are the working ranges we see across client accounts and audit requests. Treat them as orientation, not law.
Where the money actually goes
Four line items dominate.
Search visibility (SEO and content) is the largest and slowest line. It covers technical fixes, page depth for the aircraft and approvals buyers actually search — Part 145 capabilities, aircraft type + inspection interval, discovery flight + city — and the unglamorous work of making a decade of real capability legible to Google. It compounds: the enquiries it produces cost nothing extra per lead.
Paid search is the fastest and most wasteful line in equal measure. Done well, it puts a flight school in front of someone searching "discovery flight near me" the same day. Done carelessly, it bids on broad terms, skips negative keywords, and sends Part 135 buyers to a homepage built for flight training. The fix is usually not more spend — it is tighter targeting and honest landing pages.
Website and conversion work is the line most operators underfund. The site is the one asset every other dollar points at. When a site wins page-one rankings but converts at a fraction of a percent, the problem is not the traffic — it is titles, descriptions, and proof that do not give a flight department a reason to make contact.
Tools and CRM is the smallest line and the most neglected. If enquiries land in a shared inbox and nobody owns follow-up inside 48 hours, every other dollar leaks.
Judging a line item
Three questions, in order.
What enquiries did it produce last month? Not impressions, not clicks — enquiries a human could name. If the answer is unknown, that is the first fix: every channel needs a way to attribute an enquiry to it, even a simple "how did you find us" on the form.
What did each enquiry cost? Divide monthly spend by qualified enquiries. Compare against what a customer is worth. A charter operator whose direct booking is worth five figures can absorb a high cost per enquiry that would bankrupt a discovery-flight funnel. The number only means something against your ticket size.
Is the channel producing the right buyer? High enquiry volume from the wrong buyer is the most seductive waste in aviation marketing. Thirty enquiries for scenic flights does not help an operator chasing medevac contracts. Kill the mismatch, even if the volume looks good in a report.
The quiet alternative
Before adding spend, most operators have an unearned gain sitting in place. We audited a batch of aviation sites recently where pages ranked on page one for buyer searches — flight school marketing, charter marketing, MRO terms — and received thousands of monthly impressions with almost no clicks, because the titles and descriptions read like category labels instead of answers. That traffic was already won. The fix was a spreadsheet and a deploy, not a budget increase.
