US airport status directory

245: every large hub plus the 150 busiest medium airports with scheduled service, across 50 states and DC.

The FAA feed lists no ground stop, closure or delay program for it at the snapshot time. Local airline delays can still occur.

The FAA updates continuously and we poll once a minute. Pages are cached for up to 60 seconds, and the snapshot time is shown on every page.

The directory covers airports with scheduled passenger service and an IATA code. Smaller fields appear only when they have an active FAA event.
