DENVER — As Denver International Airport (DIA) approaches its 25th birthday, it continues to set new records for passenger totals.

A record-setting 69 million passengers passed through DIA in 2019, according to a release from the airport. That makes for a seven percent increase over 2018, which held the previous record, the release said. 

“As DEN [DIA] prepares to celebrate our 25th birthday later this month, we are reflecting on the past 25 years of growth,” airport CEO Kim Day said in a release. "When DEN [DIA] opened, many naysayers said the airport, which was built for 50 million passengers a year, would never reach capacity. Now, 25 years later we have far exceeded our original capacity and are building to accommodate our passenger growth now and in the future with a redesigned terminal and 39 newly built gates. These improvements will allow us to accommodate the growth of our airlines and serve 90 million passengers.”
