description: Heathrow Airport Limited operates London Heathrow (IATA LHR, ICAO EGLL), the United Kingdom's principal international
  hub and Europe's busiest airport by passenger numbers, under the ultimate ownership of FGP Topco Limited - whose largest
  shareholder since December 2024 is Ardian, alongside Saudi Arabia's Public Investment Fund and a residual Ferrovial holding.
  In the travel distribution chain Heathrow is infrastructure, not an intermediary - it sells no seats, holds no bookable
  inventory, issues no PNRs or e-tickets, and sits entirely outside the GDS and IATA NDC value chain, earning aeronautical
  charges, retail concessions, car parking and property income instead. Its API posture is unusual for an airport - Heathrow
  does run a real, branded, publicly reachable developer portal at developer.heathrow.com, built on Microsoft Azure API Management,
  which publicly describes three products in prose - Flights, Flight Connections and Weather - but publishes no OpenAPI, no
  endpoint reference, no rate limits, no pricing and no SLA to anonymous visitors. The API catalogue and Products list return
  empty to unauthenticated callers, sign-in is via Azure Active Directory, and the portal's own How It Works page requires
  a prospective developer to email support@heathrow.com and be enrolled before any access is granted. The gateway at api.heathrow.com
  goes further and rejects requests with "400 No required SSL certificate was sent", meaning mutual TLS with a Heathrow-issued
  client certificate. So - public docs, gated contracts, no exit path beyond a UK GDPR data portability request to privacy@heathrow.com.
