Madrid Airport (MAD) will drive you mad! It's less of an airport and more of an Olympic sport. I…read moredon't think I've walked this much in an airport in my life. You don't go to your gate here, you migrate. The herding cattle comparison feels generous.
And the S gates! Those aren't gates. That's another country. Possibly another time zone. You'll clear security, think you're close, and then walk for what feels like a TED Talk's worth of time. Trains, corridors, more trains, more corridors.
This place can absolutely accommodate mass movement of humans in every emotional stage of travel: aloofness, confusion, rage, and finally acceptance.
