Denver International Airport (DEN) Check-in Rule-Book & Passenger Manual

Standing in long airport check-in lines will be one of the most time-consuming parts of your journey, and departures from Denver International Airport (DEN) are no exception. As one of the busiest airports in the world, DEN handles millions of travelers every year, making its terminals especially busy during peak travel seasons, holidays, and daily rush hours. For passengers who arrive without completing online check-in, navigating crowded check-in halls and finding the correct airline counter can add unnecessary stress and delays.

To make your departure smoother, it’s always beneficial to know the DEN check-in process, your airline’s check-in counter location, and your arrival time at the airport. Whether you are flying with a domestic or international carrier, this guide provides a complete overview of the Denver International Airport check-in procedure, including terminal areas, levels, counter zones, and special services such as curbside check-in, Premier Access, and bag drop facilities. 

An Overview of Denver International Airport Check-in

Unlike many large airports with multiple passenger terminals, Denver International Airport (DEN) operates from a single central terminal known as the Jeppesen Terminal. All the DEN check-in facilities, ticket counters, baggage drop areas, and security checkpoints are located conveniently inside this terminal before passengers continue to Concourses (Gates) A, B, or C.

The Jeppesen Terminal is divided into two primary departure levels used for DEN check-in:

  • Level 6 serves as the primary ticketing and departure level for major airlines such as United Airlines, Southwest Airlines, and Frontier Airlines. Travelers will also find curbside check-in services for select airlines on this level.
  • Level 5 currently accommodates many domestic and international airlines as part of the airport’s Great Hall modernization project. Airlines operating from this level use temporary ticket counters and baggage drop facilities.

Regardless of which level your airline uses, passengers complete check-in first, proceed through TSA security screening, and then travel to their departure concourse via the underground Automated Guideway Transit System (airport train) or the pedestrian bridge to Concourse A.
