A family does not travel on one document.
It travels on eleven. Four people, four passports, two Global Entry memberships that renew in different years, a PreCheck that quietly came with one of them, and a CLEAR account somebody stopped paying for. The one that expires is never the one you were thinking about.
What it watches
Every credential
Passports, Global Entry, TSA PreCheck and CLEAR — per person, with the renewal window that actually applies to each one.
The lead time, not the date
Global Entry renewals take four to six months. You are told to start when starting still works, not when the card stops.

One answer at the top of the page, derived from the documents themselves — not a number somebody typed in.
