Yes. We can add your Known Traveler Number, which TSA PreCheck and Global Entry use, to your flight booking. Enter it yourself in your Traveler Portal or send it to hello@christianexpedition.com and we will add it for you. It does not guarantee PreCheck on every boarding pass, since that is decided by TSA and the airline, and these are U.S. programs, so they apply when you depart from a U.S. airport. Questions? Call us at (877) 234-3002.
