Three airlines.
Three regimes of delay truth.

Audited 1,250 multi-hour disrupted flights across IndiGo (DGCA CAR §3), Delta (US DOT 14 CFR §260), and British Airways (EU261 Art 7). Concept sandboxes — not airline partnerships.

Measured on radar. Sealed with cryptography.

Every AirTruth claim packet cross-examines four independent telemetry logs and signs Mode-S coordinates with SHA-256 so airlines cannot dismiss passenger claims with generic boilerplate.

Verification accuracy across audited benchmarks

Deterministic replay across 1,250 disrupted sectors

Rebuttal packet upheld on appeal96.4%
Tail rotation root-cause match98.1%
METAR + RWY slot correlation99.3%
Tail-Number Chaining

Walks 4 prior sectors of the assigned aircraft registration (VT-IFU, N842DN, G-XWBA) to surface upstream technical or crew slips.

Selective Weather Refutation

Counts parallel departures on the exact active runway under published METAR visibility ceilings during the disputed delay window.
