We don’t have an hour-by-hour security wait profile for General Mitchell International 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 large airport, plan on arriving about 2 hours before a domestic flight and 3 hours before an international one. Large hubs run multiple departure banks, so security tends to surge in the early morning (roughly 5–8 am), around midday, and again in the late afternoon.
If your schedule is flexible, midday and mid-evening departures typically see shorter security lines than the first bank of the day. TSA PreCheck lanes, where open, usually cut the wait substantially at hubs this size.
