The worst airport gate in America is 35X at Washington National across the rover from D.C. You descend an escalator into a crowded pit with insufficient seating, where you wait to be dispatched into crowded buses that take you across the airport. And your reward for this has been a cramped American Eagle 50 seat regional jet.
On April 20th though 35X will be replaced by an entirely new concourse that supports larger aircraft, features an Admirals Club, as well as upscale dining options.
