Today (Friday) CIU security is expected to be busiest 7 AM–9 AM (10–30 min) and quietest 12 PM–2 PM (5–15 min).

Security checkpoints at Chippewa County International Airport open before the first morning departures, which at most U.S. airports means around 4–5 AM (earlier at some large hubs). Hours differ by checkpoint and terminal, so for a very early flight confirm on the official CIU website.

Follow the Departures signs to the upper or departures-level curb for your airline. Curbside stopping is for active loading only; at peak hours (7 AM–9 AM) allow extra time for curb traffic. Cell-phone lots and parking rates are listed on the official CIU website.

PreCheck lanes usually run during the main morning-to-evening operating hours but can open later and close earlier than standard lanes, and not every checkpoint has one. Outside those hours PreCheck travelers are screened in the standard lane, so plan for the standard wait.

Airlines and TSA recommend 2 hours before a domestic flight and 3 hours before an international one. At the busiest hour today the CIU security line alone can reach 30 minutes; use the calculator on this page for your flight time.

They are modeled estimates refreshed every 15 minutes, not a camera or sensor count at the checkpoint. They combine FAA passenger volume, TSA's daily national screening numbers, the hour, weekday, holiday periods and current FAA and weather conditions.
