So maybe we should start randomizing MAC adresses whenever Wifi is turned on.
(Would it be a privacy problem if MAC adresses were very short-lived? I really don't know.)

And sniffing for probe requests is way more revealing than just sniffing MAC addresses. Only real solution is to turn off all WiFi and bluetooth devices, latter is getting harder and harder with smart watches, wireless headphones and other stuff.
That being said I'm not worried about being tracked while I move through an airport, since they already have cameras. Also your ticket is pretty telling, they know when it gets printed out, when it gets scanned in security and when it's scanned in the boarding, so you have always been tracked. This just brings more accurate data how long it takes for you to get from point A to B.
