Airport Security Guide

Colorado Springs (COS) Security Tips

COS has 2 security checkpoints with TSA PreCheck lanes and CLEAR biometric lanes. Security is busiest Weekday mornings (roughly 5–8am) and some afternoons (4–7pm); holiday periods can also run longer at this otherwise fast-moving small airport. Use the Leave-By Time calculator to fold the modeled COS wait forecast, your drive, and gate-walk into one exact departure time.

How many security checkpoints does COS have?

COS has 2 security checkpoints across 1 terminal (Main). TSA PreCheck dedicated lanes are available, giving members a faster, bin-free screening experience. PreCheck is open at the main checkpoints during regular screening hours, though an individual lane can close off-peak. CLEAR biometric kiosks are also deployed at COS, letting enrolled members skip the ID-verification queue entirely. See CLEAR at COS for details.

When is COS security busiest?

COS security lines are typically longest during Weekday mornings (roughly 5–8am) and some afternoons (4–7pm); holiday periods can also run longer at this otherwise fast-moving small airport. Outside those windows, wait times drop substantially — check the COS wait forecast for the current picture before you head out. General guidance:

• Domestic flights: arrive at least 2 hours before departure; 2.5 hours during peak periods.
• International flights: arrive at least 3 hours before departure to cover check-in, security, and any customs pre-clearance.

Not sure when to leave? The Leave-By Time calculator uses the modeled COS wait forecast, real-time traffic, and your gate-walk distance to give you an exact departure time. Also see how early to arrive at the airport for a full breakdown by flight type.

Which COS security checkpoint is fastest?

The east checkpoint has the CLEAR lane, so CLEAR members should use it; otherwise the east and west checkpoints see comparable traffic — use whichever is closer to your airline's ticket counter..

CLEAR is available at COS and can be stacked with TSA PreCheck for the fastest path through security: CLEAR handles the biometric ID verification, PreCheck handles the bin-free lane. If you frequently travel through COS during peak windows, combining both programs is the most effective approach. See CLEAR at COS for kiosk locations and current status.

What are the top COS airport security tips?

These tips are specific to Colorado Springs (COS) and verified against current airport configuration:

• COS has just two checkpoints (east and west) on the terminal's upper departure level; both feed into the same connected concourse, so you can enter at either one regardless of which gate (1–12) you're departing from.
• TSA PreCheck lanes run on a published daily schedule rather than being open all airport hours (roughly 4am until between 5pm and 8pm depending on the day) — check the current schedule before counting on it for a very early or late flight.
• CLEAR biometric lanes are only at the east checkpoint, not the west — plan your checkpoint choice accordingly if you're a CLEAR member.
• COS is compact (under 1,000 feet from ticket counter to the farthest gate), so 60–90 minutes before a domestic flight is comfortable even during the morning peak; the airport itself recommends at least 90 minutes before departure.
• If you're on the seasonal Southwest Cancún flight, budget extra time on arrival (not departure) for Customs and Border Protection processing through the Gates 14–18 Federal Inspection Station.

Does COS have TSA PreCheck?

Yes — COS has TSA PreCheck lanes at its security checkpoints. PreCheck members keep shoes, belts, light jackets, laptops, and 3-1-1 liquids packed, and pass through a dedicated screening lane. Membership costs $85–$100 for five years and includes a Known Traveler Number (KTN) you add to every booking.

See live PreCheck wait times and current lane status on the COS TSA PreCheck page. That page also covers which terminals have a PreCheck lane, enrollment locations, and how PreCheck compares to CLEAR and Global Entry at COS.

Global Entry interviews can be completed at COS itself — via an on-site enrollment center or Enrollment on Arrival after an international flight — and membership includes TSA PreCheck. See Global Entry at COS for locations and hours.
