Working notes, case studies, and research excerpts from the models and engagements we run. Structured so you can read the headline, the evidence, or the methodology — whichever you need.
1,033 sweet-spot routes within the UK carry no scheduled service today. Modelled latent demand tops 4 million passengers per year. Glasgow Prestwick and a cluster of London general-aviation airfields dominate the top-50.
Tier-3 gravity-model output · UK-domestic scope.
Replacing straight-line distance estimates with real road routing shrinks the airport catchment universe by 40%. Water-adjacent airports (Southampton, Borkum, London City) lose the most phantom cities — and the model finally reflects reality.
18.8 M pair-wise drive times, OSM-routed.
The competitive window is narrower than the industry assumes. On corridors with direct high-speed rail, STOL loses on almost every door-to-door comparison. The unserved opportunity sits where rail gaps, estuary geography, or schedule mismatch open a window.
Journey-time comparison methodology.
Elstree, Biggin Hill, Southend, London City, Schleissheim, Oberpfaffenhofen — recurring names in our top-unserved lists. Close to major populations, runway-qualified, already in the airport cadastre. The seed-site playbook writes itself.
