About security at Chicago Midway International Airport
Chicago Midway International Airport (MDW) serves Chicago, IL. It is a large airport with steady passenger volume through most of the day, so the standard lane rarely empties out completely, which shapes how the wait behaves: expect the longest lines when several departures cluster in the same hour, and much shorter ones in between.
TSA PreCheck status at MDW is tracked live — the chip at the top of this page shows whether a PreCheck lane is open right now. PreCheck lanes usually move faster than standard screening, but they are not staffed at every hour, so check before counting on one.
The number above is measured for the standard lane and refreshed continuously. Waits can change quickly at MDW, so recheck this page shortly before you leave for the airport.
