Schipol, from gate arrival through security check to reaching my departure gate, 15 minutes. Sorry, wasn't alert enough to set my stop watch. I realize that almost no one cares about the time it takes to process me through airports, but I figure that someone out there is mining data on traveler perception of airports, and this is my contribution. Plus it amuses me in an environment otherwise largely devoid of amusement--unless you consider duty-free shopping to be a form of amusement. Also I have a theory that some airports are better at this than others and eventually I hope to collect enough data to prove it, at least to myself.
