Denver International Airport Facts & History
Denver International Airport was the third busiest airport in the world in 2021 according to Wikipedia.
Denver International Airport replaced Stapleton International Airport, and planners wanted to make sure there was plenty of lands to expand. Because of this, the airport is 23 miles from downtown Denver and it’s important to allow extra time to navigate traffic, park, and get around the airport when you travel.
The distinct white domes that make up the airport roof are meant to mimic the Rocky Mountains in the distance.
Although the airport code is DEN, the airport is known to many locals as DIA. It currently has non-stop flights to more than 215 destinations across the U.S. and North America, Latin America, Europe, and Asia. In 2022, a committee was formed to try and establish flights from DIA to Africa.
The airport opened in 1995, sixteen months behind schedule and $2 billion over the construction budget. Some of that overrun was due to a baggage boondoggle. Although they tried to build a new automated baggage system, when the city held a press day to show it off, reporters were surprised to find chaos instead.
Clothes and personal belongings were strewn everywhere, and the system sometimes chucked people’s luggage off at random. DIA now has human baggage handlers.
Denver International Airport is also linked to a bizarre number of conspiracy theories. Art, including “ Blucifer” the Demon Horse, and the gargoyles keeping watch over your baggage lend themselves to creepy theories.
People are also suspicious of the amount of time it took the airport to be built and the underground tunnels, which they surmise must be where we keep the Lizard People. DIA has embraced their creepy reputation, and while they explain the many theories, they never really debunk them. Hmm…
Denver International Airport Layout
There are four main sections to DIA: Jeppesen Terminal, Concourse A, Concourse B, and Concourse C. Let’s cover them all:
Jeppesen Terminal
Your first stop, and the airport hub.
The Jeppesen Terminal is the great hall where most of the airport action happens.
Services you’ll find here in the main terminal include ticket counters, baggage claim, ground transportation, security checkpoints, shops, restaurants, international arrivals, access to ground transportation, and access to all concourses.
All three security checkpoints for DIA are located in this terminal, so you’ll go through security pretty early in the process, before finding your concourse or gate.
Generally speaking, the busiest times for security are from 6:30 a.m. to 10 a.m. Because there are only three checkpoints, lines can look overwhelming. They generally move fast, but you’ll still want to allow plenty of extra time.

Concourse A
Concourse A is the only concourse you can walk to from Jeppesen Terminal, although you can take the underground train as well. The A Bridge Security Checkpoint is along the pedestrian bridge on the route to Concourse A, so you can go through security on your way.
Restaurants in Concourse A include SK Provisions, Sushi-Rama, Breckenridge Brewery, Snarf’s Sandwiches, Caribou Coffee, KFC Express, and Mesa Verde Bar & Grill (which has reasonably priced, tasty green chili, solid margaritas, and fewer crowds than a lot of other spots).
Concourse B
Concourse B must be reached by the underground train, and many United Airlines and Air Canada flights go out of this concourse. When you get to Concourse B, you’ll have plenty of dining options. In fact, one of our favorite Denver restaurants, Snooze, has an outpost here.
You’ll also find loaded hotdogs at Steve’s Snappin’ Dogs, pho at City Pho, healthy options at Modern Market, and delicious burgers and shakes at Shake Shack. You can even grab a swanky steak at Elway’s.
Concourse C
Concourse C has lots of quick food options like Einstein Bros. Bagels, McDonald’s, and SMASHBURGER & Bar. However, they also have a Root Down, a satellite of the trendy spot in LoHi (and another restaurant favorite of ours!).
Tamales by La Casita is another popular Denver restaurant with an airport outlet, and you can treat yourself to Colorado’s best ice cream – Little Man – while you wait also.
Coffee shops in airports are a seriously vital service, and my favorite is The Coffee Bean & Tea Leaf. I love it so much I seek out Concourse C just to get my caffeine fix.
