About Illinois in the network
This page rolls up every outbound route filed from a Illinois airport in the OpenFlights dataset. Click any origin in the table for that airport's full destination network, or click a destination chip to jump straight to the route-pair page with operators, distance, and connecting hubs. For the airports themselves (runways, elevation, full coordinate data), visit the Illinois airport directory.
State assignment starts from each airport's nearest state centroid, then applies hand-checked overrides where centroid distance falls on the wrong side of a real state line. JFK and LGA sit under New York, EWR under New Jersey, IAD and DCA under Virginia, MCI under Missouri, MEM under Tennessee, PHL under Pennsylvania. The destination side isn't affected either way: routes flown from any origin still link to their true destination airports.
