We don’t have an hour-by-hour security wait profile for Missoula Montana Airport yet. GateWaitTimes is collecting measurements, and this page will fill in as history accumulates. Until then, some general guidance based on the airport’s size:
As a mid-size airport, arriving about 90 minutes before a domestic flight and 2.5 hours before an international one is usually comfortable. Waits tend to peak when several departures cluster together — most often early morning and late afternoon.
Outside those clusters, lines at airports this size are often 15 minutes or less. Holiday weeks and Monday mornings are the main exceptions.
