Meanwhile, DCA (Reagan National Airport, though old-timers and cabbies and staunch Dems still call it "National Airport") is doing the opposite. Terminals A and B are now terminals 1 and 2. Gate numbers
are unchanged but now have a letter in front of them. Though the letter, of course, just identifies the corridor, not the terminal. "No airlines or gates have moved. This is just a signage enhancement project." Beats me what purpose it serves, 'cause I never had any trouble finding my gate at DCA. (Getting there by Metro, yeah, and clearing TSA; but finding my gate was easy.) But it's a nice little revenue stream for the sign manufacturers and installers. And probably for a team of consultants.
Reagan National Airport (DCA) has updated signage to reflect terminal and gate-sign terminology used at most other airports. The enhancements are designed to make it easier for travelers to navigate inside and outside of the airport.
