Wait, what's the name of this airport?
In 1998, an act of Congress renamed DCA from Washington National Airport to Ronald Reagan Washington National Airport. Apart from costing the taxpayers millions of dollars in changing signage around town, the renaming upset left-leaning locals and traditionalists. Old-school locals will refer to the airport as "National" or "Washington National," some vehemently so. "Reagan National" has slipped into local parlance, sometimes as a politcal statement, sometimes as a slip of the tongue. You can avoid the politics if you just call it DCA, which is a surprisingly mainstream way of referring to it.
