No, there are no lockers available at Reagan National Airport in Washington, DC. It is a relatively small airport. If you are a member of the US Airways club, though, you can probably store your things in their area of the airport. Typically, club members get some really nice benefits. Still, you may want to call ahead to the US Airways desk to be sure. DCA is small, so even the airlines may have areas that are too small to store passengers’ luggage.
