Follow up to my original posting…showed up at SFO early and went to the lonely KLM counter….showed my passport and iWallet….gave them my KTN…minute later I had a paper tix with TSAPreCheck and more import, Sky Priority….zipped thru security and a few minutes later, was able to chill in the small Air France lounge. Funny, my KLM return flight online check in had TSA Precheck posted again, along with SkyPriority.
