"Why was our flight delayed? IndiGo texted it’s bad weather in Delhi."
Not weather. This plane had a crew duty timeout in Mumbai 6 hours earlier. Its earlier Pune→Mumbai flight hit the 12-hour pilot limit with no standby crew—long before any weather.

Airlines call almost every delay “Weather”. Radar shows the receipt.

“Weather” excuses rebutted
Share of exempted claims refuted by radar & tail logs
38.4% of rebutted airline weather claims trace back to a 4-leg inbound tail-number chain delay starting hours earlier.

Your delay began four airports away.
On the departure board it reads Bad Weather. On tail-number telemetry, aircraft VT-IFU was already 160 minutes behind after a crew FDTL timeout in Mumbai.
Six detectors built for every airline exemption excuse.
When a carrier invokes extraordinary circumstances, AirTruth audits tail history, adjacent runways, METARs, and crew hours to surface legal proof.
4-leg rotation slip
Traces the exact airframe tail (e.g. VT-IFU or N842DN) across its prior 4 flights before your gate opened.
AIRTRUTH PROVESVT-IFU slipped +145m in Mumbai 6h earlier. The aircraft was late long before Delhi cloud cover existed.
8 peer runway takeoffs
Proves adjacent jets departed the identical runway during the airline’s alleged “unflyable weather” window.
AIRTRUTH PROVESVIDP RWY 28 logged 8 clean departures under 6,000m VMC METAR while 6E-214 blamed storms.
FDTL / FAR 117 timeout
Flags cockpit & cabin crew exceeding statutory duty ceilings with zero standby reserve crew scheduled at base.
AIRTRUTH PROVESFlight deck hit 12.2h / 12.0h DGCA FDTL ceiling in Mumbai. Crew shortage is never extraordinary weather.
Zero ATC Ground Delay
Cross-checks FAA NAS Advisories and Eurocontrol ATFM bulletins whenever an airline blames air-traffic flow control.
AIRTRUTH PROVESNo FAA Ground Delay Program or airspace closure existed at KJFK between 10:00 and 15:00 UTC.
Pushback to wheels-up
Measures door-close to takeoff duration on ADS-B ground squawk logs against US DOT 3-hour & UK261 rules.
AIRTRUTH PROVESG-EUUR held on Heathrow stand/taxiway 195 minutes with no gate return — breaching tarmac charter.
One-click legal docket
Bundles timestamped lat/lon/alt transponder pings, raw METAR, and statute citation into a SHA-256 JSON claim packet.
AIRTRUTH PROVESPacket AT-VTIFU sealed with 5 Mode-S coordinates & SHA-256 proof for immediate €600 / $650 / ₹10,000 filing.
Trackers show when you landed. AIRTRUTH gives you the radar receipt.
Everything runs right on this website: paste your flight code or PNR SMS above, verify whether other jets departed the same runway cleanly, and download your own signed statutory demand packet—keep 100% of your payout.
Show live map dots and raw delay minutes, but leave you on your own to look up METARs, prove selective weather lies, or cite EU261 / DGCA / US DOT law.
Paid pro tools surface internal airline GDS codes or FAA tower alerts—great for status, not built to output SHA-256 passenger claim packets or grievance letters.
Charge ~25–35%+ of your statutory payout to file paperwork. AIRTRUTH builds your exact radar contradiction docket and pre-written demand letter right here for zero fee.

Public radar beats airline boilerplate. Every time.
AirTruth fuses transponder history, airport meteorology, and parallel departures into one signed timeline before generating a passenger claim packet.
Eight widebodies taking off from the same runway under VMC visibility is hard proof against extraordinary-weather denials.
Tracks each registration tail back across prior hubs so morning mechanical or crew timeouts aren’t relabeled as evening weather.
Every packet seals ICAO24 hex, UTC timestamps, latitude/longitude, and altitude under deterministic SHA-256 verification.
Deterministic statute math. Signed coordinates, not guesses.
Compensation tiers, rebuttal thresholds, and regulatory charters are encoded as versioned policy. Once telemetry contradicts an excuse, the payout packet is automatic.

Questions passengers ask first.
Straight answers on how claims work. See the verification method for full statutory formulas.
01How does AirTruth prove a weather excuse is false?
It fuses four live aviation streams on every flight: the specific tail number’s prior 4 rotation legs from ADS-B, airport METAR visibility/ceiling observations, parallel runway departures showing how many jets took off cleanly in the same window, and FAA/DGCA Ground Delay Program logs.
02What makes Tail-Number Chaining legally decisive?
Your flight wasn’t delayed by afternoon rain if the assigned airframe—such as VT-IFU—already slipped 3 hours earlier due to a Mumbai crew timeout or turnaround defect. Prior cascading operational delays remain airline-attributable under EU261, UK261, US DOT, and Indian DGCA charters.
03What is inside the statutory payout claim packet?
A deterministic JSON/docket bundle containing the contradicted excuse, 4-leg rotation timestamps, simultaneous runway departures, raw METAR string, crew FDTL exhaustion log, exact statute calculation (€600 / $650 / ₹10,000), and cryptographically SHA-256 signed ADS-B coordinates.
04Can airlines or claims platforms embed this or use it directly on the site?
Both. Passengers can enter any flight number directly on this site for instant claim verification, and engineering teams can call the verification API or embed the AirTruth Flight Widget in travel portals to emit signed claim packets automatically.
05Which passenger compensation laws are supported?
Three complete statutory profiles ship out of the box: EU Regulation 261/2004 (and UK261), US DOT 14 CFR Part 259/260 automatic cash refund & tarmac rules, and India’s DGCA CAR Section 3, Series M Part IV charter.
06Does AirTruth ever fabricate weather or telemetry facts?
Never. Every claim packet and passenger explanation is deterministically derived from timestamped Mode-S pings, NOAA/IMD METAR reports, and airport slot logs. Any optional language phrasing is strictly checked against the verified record.
