Navigating Denver International Airport for a flight on Frontier Airlines means heading directly to Concourse A or Concourse B, depending on your specific departure gate. Most mainline Frontier departures use the expanded gates in Concourse A, while seasonal or overflow volume can occasionally utilize other areas. If you're flying out of DEN, knowing your concourse ahead of time saves you from wandering past the Jeppesen Terminal's central security checkpoints without a plan.
Frontier operates as one of the primary ultra-low-cost carriers out of its major hub at Denver International Airport. Because DEN relies on a single main Jeppesen Terminal connected to three midfield concourses via an underground train system, knowing how to route your baggage drop, security screening, and train ride is essential for making your flight without a stressful sprint.
Locating Frontier Airlines at Denver International Airport
Frontier passengers check in at the main Jeppesen Terminal. Depending on whether you're checking bags or heading straight to security with a mobile boarding pass, you'll want to target the specific ticket counters designated for the airline.
Once you clear security, you must take the underground passenger train or walk across the pedestrian bridge to reach your assigned concourse. Frontier gates are heavily concentrated in Concourse A, though updates to airport operations mean you should always double-check your boarding pass right before heading to the gate.
- Check bags at the main Jeppesen Terminal counters on Level 6.
- Clear security at either the North, South, or A Bridge security checkpoints.
- Take the underground train system to Concourse A or Concourse B.

Navigating Security and the Underground Train
DEN features high passenger volumes year-round, which makes security wait times notoriously unpredictable. If you're checking bags, you need to complete this step at least two hours before domestic departures. Frontier enforces strict cut-off times for luggage drop-off, typically closing bag check 60 minutes before scheduled departure.
After dropping your bags, you can choose any open security checkpoint in the Jeppesen Terminal. If you're flying out of Concourse A, using the A-Bridge security checkpoint allows you to walk straight across to Concourse A without taking the train, bypassing potential underground transit delays during peak morning rushes.
- North Security: Generally busy, serves all concourses via the train.
- South Security: High volume, connects to the underground train.
- A-Bridge Security: Direct pedestrian access to Concourse A without boarding the train.
Amenities and Gate Experience in Concourse A
Concourse A features extensive dining, retail, and seating options designed to accommodate high volumes of travelers. Since Frontier operates a high-frequency schedule with quick turnarounds, gate areas can get crowded rapidly as boarding groups form.
Arriving early at your gate gives you an advantage, as overhead bin space on Frontier flights fills up fast. Passengers who haven't paid for carry-on bags or priority boarding are often subject to strict gate checks. Reviewing the official Transportation Security Administration guidelines for liquid limits and personal items helps prevent delays at the checkpoint.
- Seating: Gate areas feature standard seating, though power outlets can be scarce near older gates.
- Concessions: A wide variety of local Colorado restaurants, fast-casual spots, and grab-and-go kiosks line the central spine of Concourse A.
- Boarding Process: Frontier uses a zone-based boarding system displayed on your boarding pass. Pay attention to zone calls to avoid blocking boarding lanes.
Common Mistakes to Avoid at DEN
Travelers frequently make avoidable errors when flying out of Denver on budget carriers. The sheer size of DEN catches many infrequent flyers off guard, turning a simple departure into a race against the clock.
- Arriving too late: DEN recommends arriving two hours prior to domestic flights, but peak holiday travel requires three hours.
- Ignoring gate changes: Frontier frequently shifts gate assignments within Concourse A. Check airport monitors frequently rather than relying solely on early app notifications.
- Misjudging bag dimensions: Frontier gate agents check personal item sizes strictly. Ensure your backpack or tote fits inside the metal sizing bins to avoid hefty gate fees.
