Most beautiful other than the architecture and design:
no rollaboards
no charger stations
no fast-food counters
clean rest rooms (a phenomenon at JFK, period)
no loud, yappy suits on cel phones/bluetooth devices
no mindless texters wandering around
no clueless teens in suggestive/dirty clothes (texting mindlessly, too)
no one using F this and F that, as standard grammar
no bird poop
no masses sitting at gates waiting for announcements they can't hear on the PA

Oh, the joy of the "olden days"!!
