John le Carre put in summary the primary reasons I love airports so much:

“The airport reminded Leamas of the war: machines, half hidden in the fog, waiting patiently for their masters; the resonant voices and their echoes, the sudden shout and the incongruous clip of a girl’s heels on a stone floor; the roar of an engine that might have been at your elbow. Everywhere that air of conspiracy which generates among people who have been up since dawn– of superiority almost, derived from the common experience of having seen the night disappear and the morning come.” – The Spy Who Came In from the Cold
