Private aviation has the most llms.txt files we have found. Its websites barely render.
The charter market runs on a six-hour clock: a departure in the morning, a decision at night. We measured twelve operators and brokers in September 2026 and found a strange contradiction — this sector adopted the AI-readability file faster than any we have measured, and its homepages are simultaneously the hardest for a machine to read.
The six-hour departure panic
Nobody charters a jet to browse. The call happens when the commercial flight is gone, the meeting is tomorrow, or a family member needs to be somewhere fast. The search is done from a phone at an hour when no salesperson is awake: “private jet charter cost,” “empty leg flights tomorrow,” “on-demand charter to [city].” The operator whose site answers — and is readable by the assistant that answers first — wins the flight.
What we measured
Twelve operators and brokers, September 8, 2026: robots.txt, llms.txt, homepage, no-JavaScript word count, schema. Single vantage point, honest user-agent, raw data public: per-firm CSV · full JSON.
The llms.txt leaders
NetJets, Flexjet, Jet Linx and Monarch Air Group all serve hand-written llms.txt files — 4 of 12. Two more serve an HTML page at the address. By the file alone, aviation is the most machine-conscious sector we have measured, ahead of law, medicine and luxury property. Someone in this industry is paying attention.
But the homepages are shells
Here is the contradiction. NetJets’ homepage renders {next(r["nojs_words"] for r in sorted_sector("private-aviation") if r["name"]=="NetJets")} words without JavaScript. Flexjet: 71. Wheels Up — the one operator with a deliberate AI policy — renders 2. These are marketing sites built as visual experiences, and a machine cannot experience them; it can only read them. The sector that filed the most paperwork built the least readable front doors.
What this means for an operator or broker
The opportunity is a sentence: a broker who ships a fast, plain-text site that answers the six-hour questions — cost, empty legs, aircraft for a family of six, pets on board — becomes the one name an assistant can actually quote at 1 a.m. Nobody in the sector is doing all of it. The first one who does wins the panic market by default.
Why did you measure private aviation?
Because it is the high-value, high-urgency search market where being machine-readable matters most — and because its llms.txt adoption is the highest we have recorded anywhere.
What does “no-JavaScript word count” mean?
We strip scripts and markup from the homepage and count the words left. It is our proxy for what a machine — or a slow phone on a bad connection — can actually read.
Does llms.txt help a jet operator win flights?
It signals a deliberate decision to be readable, which is rare and quotable. But it only helps if the site itself is readable too — which is exactly where aviation falls short.
Can you guarantee more charter leads?
We can guarantee the work: a fast, readable site that answers the six-hour questions, and honest measurement. Nobody can guarantee the algorithm.
