Washington Ronald Reagan National Airport (DCA)
My mother-in-law's favorite airport. Not for nothing!
American Airlines, connection only
Current Grade: A (June 2018)
The natural light! Some of these mid-Atlantic & southeastern airports really have that figured out. It feels more like a shopping mall or a European train station than an American airport. That's a shady compliment but I do mean it as a compliment. Good food options, clean restrooms, clear signage, American Airlines hub.
