"More than 5,000 passengers a day go through Gate 35X." does not seem correct. that is 1.8 mil passengers a year through 35X and dca only has 22M total.
"Reagan National is expected to have record passenger traffic this year, exceeding 22 million."
my wife has to use 35 X to fly DCA-hartford. the stairs are not well cleared of ice in winter. she slipped and fell once.
