Denver Airport (DEN) Terminal Guide 2026
Denver International Airport has one main building, Jeppesen Terminal, and three airside concourses: A, B and C. The underground train connects the terminal to every concourse. Concourse B is United Airlines' hub. The University of Colorado A Line departs from Level 5 and reaches Denver Union Station in approximately 37 minutes.
Denver International Airport is the 5th busiest in the US — United Airlines' major western hub and the gateway to Colorado's ski resorts. DEN has one main terminal (the iconic Jeppesen with its white tent-like roof) and three concourses connected by underground train. This guide covers every airline, every concourse, the A Line commuter rail, and car service pricing to downtown Denver and every major ski resort.

How is Denver Airport organized?
DEN has a distinctive layout: all check-in, ticketing, and security happens in the Jeppesen Terminal (also called the Great Hall), recognizable by its white Teflon-coated fiberglass tent roof. After clearing security, passengers take the Automated Transit System (ATS) underground train to one of three concourses. The train runs every 1–3 minutes and is free.
Concourse A
Airlines: Southwest, Frontier, international
ATS: First stop on ATS
Lounge: No airline lounge (Priority Pass options)
Concourse B
Airlines: United Airlines (hub)
ATS: Middle stop on ATS
Lounge: United Club + Centurion Lounge
Concourse C
Airlines: Delta, American, Alaska, Spirit
ATS: Last stop on ATS
Lounge: Delta Sky Club + Admirals Club
Important: Jeppesen Terminal is Check-In ONLY
After security, you must take the ATS train to your concourse — there are no gates in the Jeppesen Terminal itself. Allow an extra 10–15 minutes to reach your gate via the ATS, especially during peak periods. If arriving at DEN, you'll take the ATS from your concourse back to the Jeppesen Terminal to reach baggage claim and ground transportation. Arranging DEN car service ahead of time means your chauffeur is already positioned at the Jeppesen Terminal's ground transportation level by the time your ATS train pulls in from Concourse A, B, or C.

How do you take the A Line from DEN to downtown?
The University of Colorado A Line connects Denver International Airport directly to Denver Union Station in downtown Denver. The 22.8-mile line opened in April 2016 and runs every 15 minutes during peak hours.
| Station | Travel Time from DEN | Fare | Notes |
|---|---|---|---|
| Denver International Airport | 0 min | $10.50 | A Line origin — Level 5 of Jeppesen Terminal |
| 40th & Airport Blvd | 8 min | $4.50 | Northeastern suburbs |
| Peoria | 12 min | $4.50 | Aurora/eastern suburbs |
| Central Park (Stapleton) | 18 min | $4.50 | Central Park neighborhood |
| 40th & Colorado | 22 min | $4.50 | Cole/Clayton neighborhoods |
| 38th & Blake | 26 min | $4.50 | RiNo (River North Arts District) |
| Denver Union Station | 37 min | $10.50 | Downtown Denver hub — connects to all RTD light rail |
A Line Limitation: No Luggage Help, No Ski Equipment
The A Line is great for solo business travelers with a carry-on. For families, travelers with checked luggage, ski equipment, or strollers — a car service is far more practical. There are no luggage racks or dedicated storage cars, and the walk from Union Station to many Denver hotels requires additional transit. Denver car service skips that extra Union Station transfer entirely — door-to-door from DEN to your downtown hotel or Cherry Creek meeting, ski bags and all.
Ski Resort Transfers from Denver Airport
Denver International Airport is the launching point for trips to the world's best ski resorts.

Winter Mountain Driving: Why Professional Drivers Matter
I-70 West through the Eisenhower Tunnel (11,013 ft elevation) and the Rocky Mountains is subject to closures, chain requirements, and severe winter weather. Detailed Drivers' chauffeurs are experienced mountain drivers with AWD/4WD vehicles and winter-rated tires — not rental-car drivers who may be encountering mountain roads for the first time in a snowstorm. We monitor road conditions and CDOT alerts in real time and adjust routes when needed. For ski resort transfers, call (888) 420-0177.
