I’ve been switched to another flight because of delays in my layover. We’re about to depart.
I had the smoothest and quickest security check ever. There was a nifty machine that you step into that cuffs you with air, I suppose so they can see if you are carrying anything. It was very sci-fi; you enter, and it says “Air cuff on”, and blows air on you, and says “Wait for green light”. Then you wait, and a green light comes, and a door slides open, and you walk through the metal detector.
They did take a rather long time looking at my bag in the x-ray machine. I am not sure why; there was nothing terribly interesting in it.
So it goes.
