Slightly off-topic but one of the past benefit of BWI was a cheaper flight option to DC area airport. While this is still the case, access to DC area has diminished slightly due to revision of B30 bus between BWI and DC.

B30 Bus to Greenbelt Station runs hourly on Weekdays only 6AM-10PM. Previously bus operated every 40 minutes daily. (Now $7.50 one-way)

MARC Train has added service between Washington and Baltimore (via BWI Airport station) but there is only 6 runs on Sunday. ($7 one-way when purchased at station)
