Reagan National Airport is a primary hub of commuter airlines in the Northeast. Many guests find that Reagan National Airport is quite convenient due to the large number flights to places all up and down the East Coast. There are many daily nonstop flights to New York, Boston, Atlanta and Chicago. Washington National Airport is rather challenging to get to from College Park, especially during rush hour. Your best bet is to take U.S. 1 till it turns into Rhode Island Avenue.
