In April, the Washington, D.C., airport unveiled its new 14-gate concourse, a 230,000-square-foot facility built to replace its remote and cramped Gate 35X. Until recently, about 6,000 American Airline passengers rode airside buses every day to Gate 35X, where they boarded regional jets parked at 14 hardstand gates. The arrangement was the airport’s way of continuing vital service while demand stretched beyond its contiguous facilities.
