Airline Accountability Index
Which airlines cancel the most — and how often they blame an extraordinary cause (weather, force majeure) to avoid paying. The label that denies your compensation is the one Causa Real™ is built to challenge.

|---|---|---|---|---|
| 1 | 🇺🇸American Airlines Top reason: Adverse weather at origin | 1,944 | 2.27% | 83.3% |

Figures are computed live from the flights we've indexed (121,188 flights so far, from the official ANAC VRA and U.S. BTS datasets) — not an airline's complete schedule. Cancel rates aren't directly comparable across countries due to differing sample sizes; the "blamed on weather" share is the comparable accountability signal. The data is public and editorial; outputs are evidentiary aids, not legal advice.
