Navigating a major hub like Denver International Airport (DEN) requires knowing exactly where to go before you step out of your car or ride-share. If you are flying with Southwest Airlines, your journey centers around Concourse C and the Jeppesen Terminal. Understanding how check-in, security, and gate transfers work saves you from last-minute rushing and missed connections.
Southwest operates one of its largest flight schedules out of DEN, meaning the airline occupies a massive footprint within the airport. While the central Jeppesen Terminal handles ticketing and baggage drop, your actual departure gates sit out on the tarmac in Concourse C, which is connected via an underground train system.
Terminal Layout and Check-In Locations
When you arrive at Denver International Airport for a Southwest flight, your first stop depends on whether you need to check bags. Southwest ticket counters and self-service kiosks are located in the Jeppesen Terminal on the West Side.
Make sure you head to the West side doors (typically doors 600–612 for drop-offs) to stay closest to the Southwest counters. If you arrive on the East side, you will face a long walk across the main terminal to reach the opposite end.
- Ticketing and Bag Drop: Open daily, but you should arrive at least 120 minutes before domestic departures to clear baggage cutoff windows.
- Curbside Check-In: Available outside the West terminal for passengers with bags to check, which bypasses the indoor counter lines.
- Self-Tagging Kiosks: Positioned near the main queue lines to speed up printing bag tags before handing luggage to agents.

Security Checkpoints and Getting to Concourse C
Once you drop your bags and print your boarding pass, you must clear security. DEN features multiple security checkpoints, including standard lanes, TSA PreCheck, and priority lanes.
You can clear security at the main terminal checkpoints (North, South, or A/B bridge checkpoints) or use the specific security screening areas that feed directly toward the train platform. After clearing security, follow signs for the underground Automated Guideway Transit System (AGTS).
- The Underground Train: This train connects the main Jeppesen Terminal to Concourses A, B, and C.
- Ride Duration: The train ride to Concourse C takes roughly three minutes from the main terminal.
- Return Trips: Trains run continuously in both directions. Listen for platform announcements to ensure you board the correct train back to baggage claim upon arrival.

Concourse C Gates and Passenger Amenities
Concourse C serves as the home base for Southwest operations at DEN, featuring dozens of gates, dining options, and retail shops. Most Southwest flights depart from gates numbered in the C23 through C67 range.
Because Southwest does not assign seats ahead of time, boarding groups line up near the gate podiums well before departure. Concourse C features ample gate seating, though peak travel hours can make finding an open seat difficult near popular morning departures.
Dining and Shopping
You won't go hungry in Concourse C. The layout includes local Colorado eateries, fast-casual national chains, and grab-and-go kiosks. Coffee shops and bars are scattered evenly across the concourse so you can grab a drink after clearing the train platform.
Restrooms and Family Facilities
Family restrooms and nursing stations are available near the center of Concourse C, typically located close to gates C55 and C61. Water bottle refill stations are positioned near most major restroom blocks.
Animal Relief Areas
Traveling with a pet? Concourse C includes an indoor pet relief area past security, located near the center core of the concourse to let service animals or pets stretch their legs without exiting the secure zone.
Connecting Between Flights at DEN
If you have a connecting flight through Denver on Southwest, you rarely need to exit security.
- Check your arriving gate number on the monitors or via the Southwest mobile app as you exit the aircraft.
- Follow overhead signs toward the central escalators leading down to the train platform.
- Take the train toward Concourse C if your connecting flight departs from a Southwest gate.
- Allow at least 45 to 60 minutes for a standard domestic-to-domestic connection to account for train transit times and walking between distant gates.
Common Mistakes to Avoid
Travelers often stumble into a few predictable traps when flying out of Denver. Avoiding these errors keeps your trip smooth.
- Going to the wrong terminal side: Parking or getting dropped off on the East side when flying Southwest means a long, frustrating walk across the entire length of the main terminal. Always aim for the West side.
- Cutting arrival times too close: DEN is notoriously busy year-round. Security lines can stretch deep into the main terminal during morning rush hours. Arriving two hours before departure is standard practice.
- Ignoring train delays: While the underground train runs reliably, rare maintenance holds can add 5 to 10 minutes to your concourse transfer. Factor this into tight connections.
