Denver International Airport just keeps getting busier.

The airport announced Wednesday it had another record year, counting more than 80 million passengers for the first time within a full year.

Denver recorded 82 million passengers in 2024, according to DIA, up from 2023’s record by nearly 6%.

In 2024, 11 months set new records. All 12 months set records in international travel as the airport expanded with new nonstop routes such as Dublin and Istanbul.

DIA also had its busiest single-day ever in 2024 on July 7, when the airport had more than 90,000 passengers go through its checkpoints.

The airport was originally built to accommodate 50 million passengers and DIA officials have invested in upgrading its infrastructure to be able to sustain 100 million passengers a year as early as 2027. DIA is one of the largest economic institutions in the state and generates about $36 billion annually.

The airport expanded its concourses, adding about 30 new concessions in 2024 and has plans to open another 30 this year. It also debuted its faster West Security gate to speed up security wait times and is set to open the new East Security gate as soon as summer this year.

“As we see this kind of year-over-year growth, it’s essential that we continue to maintain and grow our infrastructure, ensure operational efficiency and safety, and provide a quality customer experience for our passengers,” said Phil Washington, the airport’s CEO, in a news release.

The airport has been steadily growing in the last five years. The overall growth since 2019 is up nearly 20%. The airport is seeing about 13.3 million more passengers in a year than it did before the pandemic.

DIA is the third-busiest airport in the U.S. and the sixth-busiest in the world, according to Airports Council International.

Denver’s largest carriers are United Airlines, Southwest Airlines and Frontier, according to DIA. United and Southwest both had record Denver passengers in 2024. United accounted for nearly half of Denver’s market share, capturing 47% of passengers. Southwest had 31% and Frontier made up 10%.

International travel surged the most for Denver in 2024.

The number of passengers travelling internationally grew 15% year-over-year, hitting 4.6 million travelers. It’s up more than 46% from pre-pandemic travel in 2019. Domestic travel, on the other hand, grew 18% within the same time frame.
