DIA vs. DEN: The History
Denver International Airport (DIA) is the primary airport serving Denver and the surrounding areas. It was built in the 1990s to replace the former Stapleton International Airport (DEN). The new airport was designed to handle increased air traffic and provide a more modern and efficient travel experience.
The original airport code for Stapleton International Airport was DEN, which stood for “Denver.” When DIA opened, it was assigned the code DIA to distinguish it from the former airport.
Current Airport Code: DIA
Today, the only valid airport code for Denver International Airport is DIA. The code DEN is no longer in use. All airlines and travel websites recognize DIA as the official airport code for Denver.
Why Use DIA?
There are several reasons why you should always use DIA when booking flights or searching for information about Denver International Airport:
- Official Airport Code: DIA is the official airport code assigned by the International Air Transport Association (IATA). It is recognized by all airlines and travel agencies worldwide.
- Avoid Confusion: Using DEN may lead to confusion and potential travel delays. Airlines and ground transportation services may not recognize the outdated code.

You may still encounter references to DEN in older travel documents or historical records. However, it’s important to note that it is no longer used for active flight operations.
What if I Booked a Flight with DEN?
If you have already booked a flight using the code DEN, don’t worry. Airlines are aware of the code change and will redirect you to the correct airport (DIA).
However, it’s always recommended to double-check the airport code on your flight confirmation to ensure accuracy.

- Denver Arapahoe County Airport (APA): A general aviation airport located southeast of Denver.
