SDF airport carries traffic at a moderate level in our data. The live radar on this page answers the right-now question of which aircraft are inbound to and outbound from SDF at this moment, and the arrivals and departures pages linked above the radar show how each flight is running. The sections below add the longer view, drawn from a full month of our own reception data, and point you to the airline and airports connected to SDF on this site.

What our own measurement shows at SDF

Everything in this section is our own material: a 30-day reception measurement, not a schedule copied from elsewhere. Over 30 days we logged every aircraft our receivers could hear near Louisville's airport, and that log works out to an average of 4.9 aircraft observations per day. Within our dataset, that average goes together with a moderate traffic level for SDF.

The busiest window in those 30 days fell between 02:00 and 04:00; no other stretch of the measured day produced more observations. One thing to keep in mind when reading that window: our measurement clock keeps UTC, not Louisville local time, so convert those hours before you compare them with your own plans. And because the log only contains what our receivers actually heard, it will not match an official count published by the airport itself.

Southwest Airlines at SDF

Southwest Airlines is the only carrier our measurement registered at SDF, with 8 observations near Louisville in the same 30-day window. Set against the daily average measured above, that makes Southwest a modest but regular presence in the traffic we heard. The count of 8 is a measurement over 30 days, not a share of all traffic at the airport, and it is the only carrier-level figure our data holds for SDF. If the flight you are meeting or boarding is a Southwest flight, the quickest route is to look up its flight number on the Southwest flight status page instead of scanning the full arrivals or departures page.

Nearby airports

Three airports in our database appear as alternatives to SDF, and all of them involve a real trip from Louisville. Blue Grass Airport is the nearest at 100 km. Owensboro Daviess County Airport lies at 134 km, and Cincinnati Northern Kentucky International Airport is almost the same distance out at 135 km, so those two are practically equal alternatives on distance alone. With the closest option a full 100 km away, none of these is a quick fallback when a flight at SDF is delayed; treat them as planning alternatives for a diversion or a fare comparison rather than a same-hour switch.
