To start your trip off right, let’s explore every aspect of the frontier airlines denver terminal from top to bottom.
Frontier Airlines at Denver International Airport: A Hub Like No Other
Denver International Airport (DEN), often referred to simply as DIA, is the largest airport in the U.S. by land area and one of the top ten busiest in the country by passenger volume. For Frontier Airlines, this airport is not just a stop along the way—it’s home. Frontier’s headquarters are based in Denver, and it uses DEN as the central hub for a vast number of domestic and international flights.
Operating out of Concourse A, the frontier airlines denver terminal has been optimized to support a high volume of daily flights. This includes direct service to major cities, regional routes, and even select international destinations. Because Frontier operates on a low-cost model, knowing how to efficiently navigate the terminal can help you avoid unexpected delays, added fees, and unnecessary stress.
Getting to the Terminal: Where It All Begins
Your journey through Denver International Airport starts at the Jeppesen Terminal, the airport’s primary entrance hub. Frontier Airlines check-in counters are located on the east side of Level 6, clearly marked with signage. You’ll also find a number of self-service kiosks in this area, allowing for a faster check-in process, especially if you've already checked in online and simply need to print your boarding pass or baggage tags.
From there, you’ll proceed to Concourse A, where Frontier flights are assigned. You have two primary options to reach the concourse:
The Pedestrian Bridge – Ideal if you want a scenic walk and prefer avoiding escalators or elevators.
The Airport Train – A quick and efficient underground shuttle that connects all concourses. Most travelers opt for this, especially when short on time or hauling luggage.
Inside Concourse A: Your Frontier Flight Awaits
Once you arrive at Concourse A, you’ll find a terminal that is both modern and functional, designed to handle the steady stream of Frontier passengers. The terminal has recently undergone upgrades to enhance the experience for budget travelers while maintaining Frontier's fast-paced boarding and turnaround times.
Ground Boarding Expansion
A major innovation in the frontier airlines denver terminal is the introduction of 14 ground boarding gates located on the east side of Concourse A. These gates use mobile stairs and switchback ramps to facilitate dual-door boarding, meaning passengers can enter and exit the aircraft from both the front and rear doors. This drastically reduces boarding times and improves flight punctuality.
The boarding area features:
Spacious waiting zones with charging stations
Natural lighting for comfort and ambiance
Digital gate displays with flight information
Modern seating arrangements including areas for families and travelers with accessibility needs
This setup is especially beneficial for ultra-low-cost carriers like Frontier, allowing for fast aircraft turnaround and a smooth passenger flow even during peak travel hours.
Check-In, Bag Drop, and TSA Screening
Frontier encourages all passengers to check in online or via its mobile app up to 24 hours in advance. Doing this not only helps you skip lines at the airport but can also save you significant money on baggage fees.
At the airport, options include:
Self-service kiosks to print boarding passes and bag tags
Customer service counters for special assistance, such as oversized baggage or complicated itineraries
Bag drop stations for those who have checked in online
After checking in and dropping off your luggage (if applicable), proceed to TSA security screening. Lines can get long during peak travel hours, but there are dedicated lanes for:
TSA PreCheck
CLEAR members
Passengers with disabilities or mobility issues
Once through security, you’ll be on your way to your departure gate in Concourse A.
