So I've just decided to give up an give in and accept that weird things happen to me when I travel. This time I didn't even get out of my home airport! I was scheduled to leave from Gate 21. Now there are only about 26 gates at the airport so I just boogied to the far end. Let's see - gate 20, 22 and 24 on this side. Even Odd so that's easy. I turn around and see gates 23, 25, 27.
So I check again, nope not on this side. Nope, not on that side. No gate 21 anywhere.
So I ask a friendly passing airport worker. He takes me back down the concourse! Yes it turns out that gate 21 is BEFORE you get to gate 19. No clue why.
Fortunately the rest of the trip went well.
It's just one long adventure for me.
