How the tracker works
Navlytix combines free community ADS-B receivers with Flightradar24 data for ocean coverage, dead-reckons the aircraft between position reports so it moves continuously, and computes the arrival estimate from live distance-to-go and ground speed rather than the airline's published revision. You can also replay past flights and browse the route's history.
