Connection Risk API

Stop guessing connections. Score them.

Real-time missed-connection probability and buffer recommendation for any flight-to-flight connection.

Worldwide Coverage

Reliable and accurate flight delay data from the Top 20 major airports worldwide.

Connection Risk

Live operational signals + historical performance + typical terminal transfers.

Fast & Reliable

Ultra-fast API infrastructure with the popular formats and simple access by API Key.

Reduce

Reduce rebooking cost by prioritizing at‑risk connections before they break.

Protect

Protect customer experience with proactive messages and smarter re‑shopping.

Tune

Tune MCT policy using observed transfer performance by hub/terminal.

We return a miss connection probability (0–100%) plus the top drivers behind the score — not a black box.

How it works (Steps)

  1. Inputs — arrival flight, departure flight, hub (IATA), flight date.

  2. Engine — combines schedule buffer, carrier/airport reliability, deplane time variance, walk/transfer times, and typical security/immigration.

  3. Output — miss connection risk (historical), miss connection risk (live), miss connection risk (live+15), recommended buffer, key drivers.

Use cases

  • Airlines/alliances: IRROPs triage; protected connection logic; seat/gate prioritization.

  • OTAs/metasearch: Sort by reliability; nudge to safer buffers; dynamic guarantees.

  • Airports: Calibrate MCT; plan signage & shuttles; inform passenger comms.

  • Insurers/cards: Underwrite trip interruption; proactive assistance triggers.

Trust, coverage & performance

  • Data sources: Live operational signals + historical performance + typical terminal transfers.

  • Latency: P50 ~200 ms (target); versioned models with changelog.

  • Privacy: No PII required. HTTPS only. Keys scoped per environment.

  • Security: Key‑based auth, optional IP allowlist. Audit logs by request_id.

  • Reliability: 99.9% target; idempotent retries recommended for 5xx/timeout.

No hidden costs. No surprises.
