the heart of frontier: denver international airport
Denver International Airport is no ordinary travel hub. Spanning over 33,000 acres, it is the largest airport in the U.S. by land area and ranks as one of the busiest in terms of passenger traffic. But more importantly, it's home base for Frontier Airlines. That means the airline has its most extensive infrastructure, flight connections, and service offerings at DEN.
Frontier primarily operates out of Concourse A — a sleek, modern area that handles both domestic and some international flights. The concourse connects to the Jeppesen Terminal, and is accessible via the airport’s Automated Guideway Transit System (AGTS) or pedestrian bridge.
This is where your Frontier journey begins.
check-in essentials at the frontier airlines denver terminal
Planning to check in at the airport? You’ll want to arrive early. Because Frontier charges fees for just about everything beyond your seat and a personal item, many travelers wait until the last minute to decide whether to check a bag, print a boarding pass, or pay for overhead bin access.
To minimize stress:
Use Frontier’s online check-in up to 24 hours before your flight.
Purchase baggage ahead of time online—it’s more expensive at the terminal.
Utilize self-service kiosks on Level 6 East of the Jeppesen Terminal to print boarding passes and bag tags.
Once checked in, drop your baggage at the designated counters and head toward the North Security Checkpoint. This checkpoint offers direct access to the pedestrian bridge connecting to Concourse A, which means you can skip the train if you prefer to walk.
navigating concourse a: your base for frontier flights
Concourse A is the nerve center of Frontier’s DEN operations. With dozens of gates dedicated to the airline, you’ll often see long lines of travelers familiar with the airline’s boarding protocol. Gates typically range from A20 to A39, though this can vary depending on traffic.
Highlights of Concourse A for Frontier travelers:
Efficient boarding gates with electronic signage for zone-based entry.
Charging stations and USB ports scattered throughout the seating areas.
Updated restrooms, including family-friendly and accessible facilities.
Ample seating, although busy periods can lead to standing room only.
dining and refreshments at the frontier airlines denver terminal
Don’t expect gourmet cuisine, but Concourse A does deliver when it comes to variety and convenience. Here are some standout options:
Modern Market Eatery: Ideal for health-conscious travelers looking for salads, wraps, and bowls.
Cantina Grill: A go-to spot for Mexican favorites and grab-and-go burritos.
Steve’s Snappin’ Dogs: A local institution that serves gourmet hot dogs, brats, and breakfast sandwiches.
Smashburger: For quick, satisfying American fare.
Caribou Coffee & Dazbog Coffee: Two solid caffeine options near the gates.
Hudson News and smaller kiosks: Snacks, water bottles, reading material, and last-minute essentials.
Pro tip: Since Frontier doesn’t provide complimentary drinks or snacks on board, be sure to stock up before boarding.
what to expect during boarding
Frontier’s boarding procedure is unique to its ultra-low-cost model. Passengers board in zones, which are printed on boarding passes and displayed on gate signage.
How it works:
Pre-boarding for those with disabilities or special needs.
Zone 1: Includes those who paid for priority boarding.
Zone 2 and beyond: Standard ticket holders, based on seat location.
Because of its fee-based structure, you’ll find that passengers who only bring personal items tend to board later. Expect lines to form quickly once boarding begins—plan accordingly if you’re aiming for overhead bin space or want to secure a spot in line early.
accessibility, kids, and pet-friendly features
Denver International Airport is known for being accessible, and the frontier airlines denver terminal is no exception. You’ll find:
Wheelchair services available at curbside and inside the terminal.
Service animal relief areas both pre- and post-security.
Nursing rooms and family restrooms with changing tables.
Play zones near the gate areas where younger children can burn off energy before a flight.
If you’re flying with pets (which Frontier allows), be sure to review the airline’s policies before arriving to avoid extra charges or documentation issues.

Amenities include:
Free Wi-Fi throughout the terminal and concourse.
Power outlets and USB charging ports near most seating areas.
Mobile boarding support, including QR scanners at gate readers.
Before your trip, make sure your Frontier app is downloaded and up to date. It offers mobile boarding passes, notifications, and flight updates.
luggage claims and connecting flights
When arriving at DEN, all Frontier flights land in Concourse A. If Denver is your final destination:
Proceed to the train (AGTS) to reach Baggage Claim on Level 5 of the Jeppesen Terminal.
Check monitors for carousel numbers.
If connecting to another Frontier flight, remain within Concourse A—there’s no need to re-clear security unless you exit.
For international arrivals, Frontier utilizes DEN’s Customs and Border Protection area, also accessible from Concourse A. Make sure you allow additional time for processing.
