Field notes
The app uses the aircraft’s existing AirFi cabin network rather than cellular service or a remote flight-data server. Its documented connection is wss://airfi.aero/adsb/, where it reads roughly one frame per second and turns those frames into a local iOS Live Activity. Sun Country Airlines is marked verified in flight, while other AirFi carriers remain untested.
