Maps are updated when terminals are renovated or new concourses open. Terminal 5 at LAX, for example, has been closed since October 2025 for reconstruction — always confirm your terminal from your boarding pass rather than relying on a saved map.
Here is what each terminal or concourse at COS handles — which airlines fly from it, the gate range, and key amenities to know before you go.
COS operates a single three-level, 275,000-square-foot terminal opened in 1994 with 12 gates split across two concourses — Concourse A (Gates 1–6) and Concourse B (Gates 7–12). Two security checkpoints (east and west) on the upper departure level feed into one continuous secure corridor, so once through either checkpoint, passengers can walk to any gate without re-clearing security. American, Delta, United, Southwest, and seasonal Allegiant flights all use this concourse; the farthest gate is under 1,000 feet from the ticket counters or baggage claim.

A separate five-gate concourse (Gates 14–18) is used mainly for charter and overflow operations. Since late 2025 it also houses a newly built ~16,300-square-foot Federal Inspection Station (FIS), where passengers arriving on Southwest's seasonal nonstop from Cancún clear U.S. Customs and Border Protection before continuing into the main terminal. It is not used for regular domestic boarding and is not accessible to typical connecting passengers.
No train, tram, or shuttle needed — Concourse A and Concourse B are joined by one continuous secure corridor after security, so passengers walk directly between all 12 main gates. The separate international arrivals facility (Gates 14–18) is only reached by arriving international passengers before they clear into the main terminal.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at COS — wait times for people-movers, buses, or security re-screening add up faster than the physical distance suggests. Build the buffer into your Leave-By time, not your gate arrival time.
COS is compact by design — the longest walk from a ticket counter or baggage claim to any gate is under 1,000 feet (roughly 3–5 minutes). Two checkpoints (east and west) serve the terminal; the east checkpoint has the CLEAR lane, so CLEAR members should enter there.
