Nearly 20 million passengers traveled through Reagan National Airport in 2012, setting a new record.

DCA’s passenger traffic increased 4.1 percent to 19.7 million passengers. The growth came during a year when industry-wide airport passenger growth was less than 1 percent. It also comes a year after Reagan National hit a then-record 18.8 million passengers in 2011.

Travelers had more travel options at DCA this past year, with US Airways and JetBlue adding new non-stop service and a new airline, Virgin America, now serving the airport.

A new construction project this year will help ease some of the crowding at Reagan National, according to the Metropolitan Washington Airports Authority.

“The airport continues to be a popular choice because of its proximity to downtown Washington,” MWAA said in a press release. “A construction project in 2013 will address some of the increased demand at Reagan National, expanding security screening areas in Terminal A to provide improved access for passengers using the terminal’s nine gates.”

While international travel grew by 2 percent at Dulles, MWAA says domestic travel was hurt by competition from DCA.

“Dulles saw domestic service declines mainly resulting from the transfer of some airline routes to Reagan National and reduced capacity on other routes,” the authority said.
