About security at Great Falls International Airport
Great Falls International Airport (GTF) serves Great Falls, MT. It is a mid-sized airport where lines build around banks of departures rather than staying long all day, 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 GTF 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 GTF, so recheck this page shortly before you leave for the airport.
