Sitting at SFO pondering imponderables...

I don't recall how I got on TSA's Pre-Check list--just assumed they recognized some inherent superiority.

So now I wonder why my boarding pass fails to identify me as one of the cool kids on about half of my flights--often within the same reservation (pre-checked on DEN-SFO and steerage class on SFO-DEN).

Is it the phase of the moon, or cosmic karma for something I did in the pre-existence?

Does this happen to anyone else?
