Navigating Denver International Airport for a low-cost flight requires knowing the exact layout before you step out of your rideshare. Frontier Airlines operates out of the Jeppesen Terminal on Level 6, East Side (Counter 2), with flights departing primarily from Concourse A. Because Denver ranks among the busiest airports in the United States, managing your timeline carefully helps you avoid missed bag drops and long security lines.
Getting from the main terminal to your gate demands a quick trip through TSA security and an automated underground train ride. If you're carrying only a personal item and have your digital boarding pass ready, you can bypass the ticket counters entirely. However, if you need to check luggage or print documents, you'll need to hit the East side counters at least sixty minutes before departure.
Jeppesen Terminal Layout and Check-In
Your journey begins in the iconic tented Jeppesen Terminal. Frontier utilizes the East Side for passenger ticketing and bag drop.
- Level 6 (Departures): Drop off passengers or head straight inside if you're checking bags. Frontier's ticket counters and self-service kiosks sit right along the East side.
- Level 5 (Arrivals): Head down here if you're landing in Denver and need to pick up baggage from the East baggage claim carousels.
Frontier strictly enforces its time limits. The ticket counters and bag drop services close exactly 60 minutes before departure. Cutting it close means your bags won't fly with you, no exceptions.
Security Checkpoints at DIA
Denver International Airport features two main security screening areas in the main terminal: the East Security Checkpoint and the West Security Checkpoint.
- Both checkpoints feed into the underground train system that connects to Concourses A, B, and C.
- Because Frontier flights leave from Concourse A, using either the East or West checkpoint works fine, though the East checkpoint sits closer to Frontier's ticket counters.
- Check real-time wait times on the official Denver International Airport Website before you leave home to decide whether you need standard security, TSA PreCheck, or the Premium/First Class lanes if eligible.
Concourse A and Gate Access
Once you clear security, follow the signs down to the underground passenger train. The train runs continuously, taking just a couple of minutes to reach the concourses.
- Frontier flights primarily board out of Concourse A.
- Concourse A features a wide array of dining options, coffee shops, and retail stores if you arrive early.
- Keep an eye on airport monitors or the Frontier Airlines Official Site for any last-minute gate changes, as operational shifts happen frequently at DIA.
Avoiding Common Mistakes at DIA
Travelers often stumble at Denver International Airport due to a few avoidable missteps. Keep these points in mind to keep your trip smooth:
- Wrong Terminal Side: Entering on the West side means a long walk across the massive main terminal to reach Frontier's East counters. Tell your driver to drop you off on East Level 6.
- Missing Bag Cutoffs: Arriving 45 minutes before departure will get you turned away at the bag drop. Always target a two-hour arrival window.
- Ignoring Personal Item Sizes: Frontier gates feature strict sizing boxes. If your backpack or tote exceeds the personal item dimensions, expect a gate-check fee. Measure your bags before leaving home.
