Every research firm claims rigorous methodology; few show their working. Since we ask operators, platforms and investors to trust our numbers on airport transfer and chauffeur markets, this article documents exactly how a World Global Travel report is built — sources, validation steps, and the honest limits of what market research can know.
Step 1 — Scope definition (the step that decides everything)
Before any data is gathered we fix, in writing: the service definition (pre-booked passenger ground transport — private transfers, chauffeured services, licensed operator shuttles; ride-hailing treated as adjacent, not core), the geography (country or region, with airports named), the time horizon, and the units (revenue in EUR, volumes in completed trips). Most disagreement between published market sizes is scope, not measurement — so we publish the scope box on page one, not in an appendix.
Step 2 — Bottom-up market construction
We size markets from the demand side up, not by trimming a global number down:
- Airport passenger volumes per hub from official airport and aviation statistics — the demand ceiling.
- Ground-transport mode split per airport from surveys, airport access studies and operator data — what share of arrivals pre-book a vehicle.
- Average transaction values by route and vehicle class from collected pricing data (see step 3).
Multiplied and summed per airport, then aggregated to country level. Top-down checks (national VTC/private-hire licensing counts, tax-registry revenue data where published) act as a sanity corridor: if bottom-up lands outside it, we investigate until we know why.
Step 3 — Primary pricing collection
Our pricing benchmarks come from a consistent basket: standard, business and van classes quoted on defined airport-to-centre routes, collected at scheduled intervals across operators and platforms, normalized to EUR at period-average rates. This is the dataset behind our Global Airport Transfer Pricing Index and the pricing chapters of country reports. Collection rules (same routes, same lead times, same pickup windows) matter more than sample size — without them, "average price" comparisons are noise.
Step 4 — Operator interviews
Numbers explain what; operators explain why. Each country report draws on structured conversations with fleet operators, dispatch platforms and DMC buyers active in that market — covering utilization, driver economics, channel mix and regulatory friction. Interviews are anonymized by default (people speak more honestly about margins that way) and are never the sole source for a quantitative claim: they validate, contextualize and occasionally veto the spreadsheet.
Step 5 — Regulatory mapping
In licensed markets, regulation IS market structure. We document the licensing regime (caps, geographic restrictions, vehicle requirements), pending changes, and enforcement reality — the gap between the law and the street. France's VTC register, Italy's NCC rules and UK private-hire licensing each get this treatment in their country reports, because supply-side caps move prices more than demand ever does.
Step 6 — Review and the uncertainty statement
Every report passes a second-analyst review with a simple brief: attack the assumptions. Forecast ranges are published with their drivers ("the spread between scenarios is airport capacity growth and licensing policy"), and figures we could not validate to our standard are labelled as estimates or excluded. A market report that admits what it does not know is more useful — and rarer — than one that does not.
What this means for you as a buyer
You can interrogate any number in our catalog by asking us which step produced it — and you will get the source category, the validation route, and the assumption set. That is the standard we would demand as buyers, so it is the one we publish to.
Frequently asked questions
Why don't you publish exact operator-level data?
Interview confidentiality and competitive sensitivity. Operator-level structure appears as anonymized patterns (fleet-size bands, margin ranges), never as named P&Ls.
How often are reports updated?
Pricing benchmarks are refreshed on a rolling basis; country reports are revised when a material driver changes — regulation, major consolidation, or a demand shock — rather than on an arbitrary annual cycle.
Can you run custom scopes?
Yes — the same methodology applied to a client-defined geography or segment. Contact us through the contacts page with the decision you are trying to make, and we will scope honestly, including telling you when an existing report already answers it.
