When booking travel which is the Airport you prefer to use? BWI Airport or Dulles Airport?
What matters most for me is the convenience of traveling with the airline I have my frequent flier miles with. This is very important as you build the more you fly. I have found that getting to Dulles is a very nice drive and travelers really like the route to the airport from Central PA. While BWI is closer sometimes depending on your travel time it can be difficult to navigate 695 in the rush hour times.
