Track Air France flights using the Air France–KLM Open Data APIs (Flight Status). Use when the user gives a flight number/date (e.g., AF007 on 2026-01-29) and wants monitoring, alerts (delay/gate/aircraft changes), or analysis (previous-flight chain, aircraft tail number → cabin recency / Wi‑Fi). Also use when setting up or tuning polling schedules within API rate limits.
- Added a comprehensive README.md with setup, usage, and implementation notes. - Clarified that the watcher script now prints no output when nothing changes, to reduce noise in cron jobs. - Updated documentation to detail input handling, polling strategies, and heuristic use of aircraft data.
