The terminal is designed to support the high volume of Frontier flights, offering an efficient and budget-friendly travel experience to passengers.

Check-In and Access

Upon arrival at DEN, passengers can head to the east side of the Terminal where Frontier’s check-in area is located. Travelers can choose from staffed check-in counters or use self-service kiosks to print boarding passes and bag tags. Baggage drop stations are also available for those checking luggage. Once check-in is complete, passengers proceed through security and access Terminal East either via the underground automated train system or the pedestrian bridge on Level 6. 

Terminal Facilities and Services

Concourse A is spacious, modern, and well-equipped to handle Frontier’s operations. It features a range of services and amenities for travelers, including:

• Dining options: The terminal offers a variety of food and beverage outlets. Whether you’re looking for a quick snack, coffee, or a full meal, you’ll find fast food counters, local eateries, and national chains throughout the concourse.

Ground-Level Boarding Facility

A notable feature of Frontier’s presence at DEN is its use of ground-level boarding gates at the far end of Concourse A. This area, developed to streamline boarding processes, includes several gates where passengers board aircraft via outdoor ramps and stairs. The design supports front and rear-door boarding, which speeds up the process and reduces turnaround times. However, this system can be challenging in harsh weather conditions or for passengers with mobility limitations.

Boarding Process

Frontier uses a zone-based boarding process. Your zone number is indicated on your boarding pass, and announcements are made over the PA system when each group is called. Passengers in earlier boarding zones usually include those who’ve paid for seat selection or carry-on bags. If you’re boarding from a ground-level gate, pay close attention to instructions, as some aircraft are boarded from the front while others require boarding from the rear. 

Arrivals and Transfers

Upon arriving at DEN on a Frontier flight, domestic passengers disembark at Concourse A and return to the Terminal by train or pedestrian bridge to reach baggage claim and ground transportation. The baggage claim area is located on Level 5 of the terminal. Clear signage makes it easy to navigate to rental cars, ride-share pickups, taxis, and public transportation. International arrivals on Frontier go through customs at Concourse A before transitioning to the main terminal. 

Ground Transportation

DEN offers a variety of ground transport options. Passengers can use airport shuttles, city buses, rental cars, or the airport rail line that connects to downtown Denver. Ride-share services and taxis are also available at designated pickup zones outside the terminal. 

Tips for a Smooth Frontier Experience at DEN

• Arrive early: DEN is a large airport, and lines at check-in or security can be long. Plan to arrive at least two hours before a domestic flight and three hours for international travel.

• Check in online: Save time by checking in online and printing your boarding pass or using a mobile version.

• Travel light: Frontier charges for carry-on and checked bags, but one personal item is free. If possible, travel with just a personal item to simplify boarding and avoid extra fees.

• Use the pedestrian bridge: If you’re traveling light, the bridge is often quicker than the train for getting to Concourse A.

• Stay informed: Monitor the departure boards and listen for announcements, especially if you’re departing from the newer ground-level gates.

Flying with Frontier Airlines from Denver International Airport can be a convenient and cost-effective experience when properly planned. Terminal East offers essential amenities, quick access from the main terminal, and multiple dining and shopping options. Ground-level boarding may require a little extra walking and weather preparedness, but it helps keep flights on schedule.
