DCA, DCA, DCA!!!!! Unless you are flying from a market serviced by Southwest Airlines. Southwest flies into BWI, therefore all the majors match those fares. Now DCA sits right in front of the Nations Capital!! and you can take the metro right from the airport over to the mall!! DCA is has the best landings!!! That is if you are flying in from the north. It's great banking hard right over the Prez's house and then landing from a bank!!
