A record number of travelers took to Reagan National Airport last year.
A record number of passengers passed through Washington area airports in 2012.
Of the 42 million passengers who passed through the two Virginia airports, 19.7 million were at Ronald Reagan Washington National Airport — the most ever. Dulles also hit a new high, with 6.7 million international passengers walked through the gates, although the number of domestic passengers dropped.
"Growth at Reagan National has in part been because of a couple of developments that we really didn't have any control over," says Mark Treadaway, the vice president for air service development at MWAA. "One is FAA reauthorization that added some additional flying. The other was a commercial transaction between U.S. Airways and Delta in which they traded some slots and we saw an increase in seats."
But Reagan and Dulles were not the busiest airports in the region. For the first time in a decade, more passengers used Baltimore Washington International Airport than Dulles.
