ATS Route Weaver draws the global flight network, 3,257 airports and 18,930 route pairs, as great-circle arcs on a dark world map. It opens on a world view of the 600 routes listed by the most airlines, then lets you click or search any airport to draw its own network: every route it serves as a bright arc, its longest and shortest legs, its top destinations, and hub-to-hub exploration with a breadcrumb trail back. The arcs are great circles split at the antimeridian, so a route across the Pacific bends the way it flies. The route table is the OpenFlights snapshot of June 2014, the shape of the network then, not current schedules.
