A Stress-Free Guide to Terminal Hopping at Denver Airport

Navigating Denver International Airport (DEN) doesn’t have to be overwhelming, even if you’re a first-time visitor. Even though it’s one of America’s largest airports by land area (and passengers), DEN stands out for its remarkably efficient terminal transfer system, especially when compared to many major U.S. airports.

While airports like Chicago O’Hare (ORD) require long walks through seemingly endless corridors, or Los Angeles International (LAX) forces passengers to exit security and take shuttles between terminals, Denver’s automated train system makes terminal hopping a breeze. At DEN, you can travel from the main terminal to the furthest concourse in just 4 minutes, all while remaining inside the secure area. This efficient design isn’t just convenient—it’s a game-changer for travelers making connections or simply wanting to explore the airport’s diverse dining and shopping options across different concourses.

Stressed is the last thing you’ll feel after I walk you through everything you need to know about terminal hopping at Denver Airport!

A Bit of History and Layout

When Denver International Airport opened in 1995, it revolutionized airport design with its distinctive white peaked roof (meant to mirror Colorado’s mountains) and its innovative underground train system. The airport consists of one main terminal, named Jeppesen Terminal, and three concourses: A, B, and C. What makes DEN unique is that all concourses are connected via an automated underground train system, eliminating the need for traditional above-ground shuttles.

Important: Do not confuse Denver’s underground train system with the Denver Airport train.

Understanding DEN’s Layout

The Jeppesen Terminal (often called the main terminal) is where you’ll find check-in counters, security checkpoints, and baggage claim. Everyone starts here. From there, the concourses are arranged in alphabetical order from west to east:

  • Concourse A: Frontier Airlines, JetBlue, United Airlines (limited gates) and international flights
  • Concourse B: United Airlines
  • Concourse C: Southwest Airlines and other domestic carriers

One helpful feature to remember is that Concourse A is the only one connected to the main terminal by a pedestrian bridge, in addition to the train system. This bridge offers stunning views of the airfield and mountains, and it’s a great backup option if you’re heading to or from Concourse A.

Using the Underground Train System

Here’s your step-by-step guide to using DEN’s automated train system:

  1. Look for the train icon on overhead signs throughout the airport
  2. Follow signs to the nearest train platform (they’re clearly marked with black and white “TRAIN” signs)
  3. Descend the escalator or elevator to the train level
  4. Wait behind the yellow safety line on the platform
  5. When the train arrives, wait for passengers to exit before boarding
  6. Hold onto handrails – the train accelerates quickly
  7. Listen for automated announcements indicating the next stop
  8. Exit when your concourse is announced

The trains stations are located in the center of each concourse. Once you exit the train, simply take the escalator (located on two sides) or elevator up to the next level and you’ll be right in the middle of concourse restaurants and shops.

Important note: Trains run continuously in both directions and make the same stops in the same order. Pay attention to the signage to get on the train going in your direction.

Travel Times Between Terminals

Here are the estimated travel times between different points:

  • Main Terminal to Concourse A: 2 minutes
  • Main Terminal to Concourse B: 3 minutes
  • Main Terminal to Concourse C: 4 minutes
  • Between any two adjacent concourses: 2 minutes
  • Full circuit (Terminal → C → Terminal): 8 minutes

Trains arrive every 2 minutes during peak hours and every 4 minutes during off-peak times, so you rarely have to wait long.

Accessibility and Special Needs

Denver Airport excels in accommodating passengers with mobility issues or special needs:

  • All train platforms are equipped with elevators
  • Level boarding means no steps between platform and train
  • Priority seating areas are clearly marked on each train car
  • Visual and audio announcements are provided for all stops
  • Wheelchair assistance is available (request through your airline)
  • Service animal relief areas are available in each concourse

For passengers using wheelchairs or mobility devices, the trains feature dedicated spaces with secure holding areas and extra handrails.

Backup Plans When Things Go Wrong

While the train system is highly reliable, it’s good to know your alternatives:

If the train system is temporarily down:

  • Shuttle buses operate between all terminals as a backup
  • The pedestrian bridge to Concourse A remains accessible
  • Airport staff will be positioned throughout to provide directions
  • Electronic signs will display current alternative routes
  • Additional staff will be available to assist passengers with mobility needs

Emergency Contingency Tips:

  • Always allow extra time for connections (minimum 45 minutes recommended)
  • Save the airport’s information number in your phone: 303-342-2000
  • Download the DEN airport app for real-time updates
  • Look for airport ambassadors in white shirts for assistance
