Enter an airline + flight number, e.g. AA3657. The tracker shows the live position if the flight is airborne, the schedule if it hasn't departed, or the most recent leg that landed within the last 30 minutes.

You ask for /AA3657. We resolve AA → American Airlines, fetch the flight from FlightStats and show scheduled vs. actual times in both UTC and the airport's local zone. Live legs include altitude, ground speed, heading and a position map.
