Why doesn t everyone get PreCheck?

TSA PreCheck is not a guaranteed service perk Though unlikely, TSA PreCheck is not guaranteed to users every single time they travel through a participating airport or airline. TSA uses unpredictable security measures, both seen and unseen, throughout the airport, according to TSA.



Not everyone receives TSA PreCheck because it is a "Trusted Traveler" program that requires a proactive application process, a background check, and an enrollment fee. Even for those who have enrolled and received a Known Traveler Number (KTN), the "PreCheck" indicator on a boarding pass is not always guaranteed; the TSA uses "random exclusion" protocols to maintain security unpredictability. Furthermore, many travelers are disqualified due to specific criminal convictions or incomplete documentation during the vetting process. In 2026, the transition to REAL ID (mandatory as of May 2025) has also affected eligibility; if your state ID is not REAL ID-compliant, you may face additional screening hurdles regardless of your PreCheck status. Lastly, many travelers simply choose not to apply because they do not fly frequently enough to justify the $78–$85 fee, or they utilize other programs like Global Entry, which includes PreCheck but involves a more rigorous interview process and higher cost.
