I understand the restrictions on building at DCA given the multiple issues that it faces between airspace, noise, buildings, etc. I also know that Terminal A is historic and relatively beautiful. What I don't understand is whether or not MWAA can do anything to the airside area of A. I do not believe it is original, as the gate area seems to be from the 1960s or so. Does anyone know more about Terminal A? Can MWAA tear down the A gates and rebuild those while leaving the historic parts of the terminal in tact? If so, why don't they? An A terminal that more closely resembled B/C would be fantastic. Thinking about retrieving luggage from A gives me nightmares.
