This is actual liminal space. The space between places.
Not some creepy old abandoned place.

St. Louis Lambert International Airport

Unless google failed me with the tunnel lol

Love this actual liminal space, the fact that there really isn't anyone around plus the lightning is beautiful. Thank you!

Nice. Not the first airport posted here.

The window without a view is a nice touch.

Also, I like that there's a travelator going between the gates. The travelators at ATL are in the tunnels between concourses and are entirely redundant with the train-type people mover.
