Great. Thanks for the responses. The process seems to keep evolving. I do remememver the CBP sticker from the first time, and although my husband and I both did GE renewals at the same time, he was randomly chosen for an interview and I was not. You indicate that passport renewal has no impact on KTN and precheck. This is as long as GOES is updated, correct? My AAd vantage account also has a passport number. The trusted traveler number doesn't change with GE Renewal. What is pas s port number used for by the airline? OLCI if available?

I'm guess I'm wondering why the passport number changes each time doesn't seem to make sense or need to.
