Both airports process about the same number of passengers. Both are extremely difficult to reach much of the day. Both are about the same distance from downtown DC. Both have an xepressway with a middle available.
Why is IAD the "natural" choice, although the only thing stopping the DC-IAD route down is the cost. There is talk of putting a "high speed" bus lane in, exclusively for DC-IAD bus traffic.
