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 DEN handles — which airlines fly from it, the gate range, and key amenities to know before you go.
The sole landside terminal building at DEN. Level 6 holds the upper road, airline check-in counters, and East and West TSA security checkpoints. Level 5 has baggage claim, ground transportation, shops, and restaurants. The Westin Denver International Hotel sits directly above Level 6. No departure gates are located here — all gates are in the three airside concourses reached by underground train or pedestrian bridge.
DEN's international concourse and the closest to the Jeppesen Terminal. Handles all international departures and arrivals (Aer Lingus, British Airways, Lufthansa, and others), as well as major domestic carriers including American, Alaska, Allegiant, Frontier, and JetBlue. Reachable either by the free AGTS underground train or by walking the A-Bridge pedestrian bridge (with moving walkways) directly from the Jeppesen Terminal — the bridge is often faster than waiting for the train.
The largest concourse at DEN, operated almost exclusively by United Airlines. Only accessible via the AGTS underground train — there is no walkable connection from the terminal or Concourse A. Sitting between Concourses A and C on the train line.
The farthest concourse from the Jeppesen Terminal, primarily serving Southwest Airlines and Delta. Only reachable by the AGTS underground train; approximately 6 minutes end-to-end from the Jeppesen Terminal station. Passengers exiting international flights at Concourse A who need to connect to Southwest or Delta must re-clear security after customs and ride the train to Concourse C.
Free underground Automatic Guideway Transit System (AGTS) train running 24/7 on a loop: Jeppesen Terminal → Concourse A → Concourse B → Concourse C and back. Trains run every 2-3 minutes; end-to-end journey to Concourse C takes approximately 6 minutes. Concourse A can also be reached on foot via the A-Bridge pedestrian walkway (with moving walkways) directly from the Jeppesen Terminal — no train required. Concourses B and C are only accessible by train.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at DEN — 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.
If your gate is in Concourse A, skip the train and use the A-Bridge pedestrian walkway from the Jeppesen Terminal — it is faster than waiting for the AGTS during peak hours. For Concourses B and C there is no walking option, so factor in at least 10-15 minutes from check-in to gate (train wait + ride + walk to gate). As of 2026 the Great Hall renovation on Level 5 is still ongoing (expected to complete end of 2027), so follow posted detour signage on that level.
A few habits that prevent last-minute sprints:
Experienced travellers at DEN use a short checklist every time:

Open your airline app about two hours before departure — gate assignments sometimes change after check-in closes. Look for departure boards throughout the terminal for real-time gate information.
