Picking someone up, or about to fly? Type the flight number on the ticket (BA117, LH400) and see where the plane is right now and when it should land, worked out from its live position, not the timetable. It says in plain words whether the flight is early or late, warns about fog, storms and wind at both airports, and lets you send the live page to whoever is picking you up. Works worldwide. Free, no sign-up, no app.
