Disqualification from the TSA PreCheck program can result from several factors, ranging from criminal history to security violations at the airport. You can be permanently disqualified if you have been convicted of "treason," "espionage," "murder," or "crimes involving explosives." However, more common disqualifications are temporary (often lasting 5 to 7 years) and stem from offenses like assault, robbery, or drug possession. Furthermore, any "Security Threat" violation will result in immediate removal from the program; this includes bringing a firearm to a checkpoint, interfering with a flight crew, or making a bomb threat. In 2026, the TSA also performs "recurrent vetting," meaning if you are arrested for a disqualifying offense after you have been approved, your status can be suspended while the investigation is ongoing. Additionally, simple administrative errors, such as a name mismatch on your government ID or failing to disclose a criminal record during the application process, can lead to a denial. Once disqualified, the "Trusted Traveler" status is very difficult to regain, making compliance with all aviation laws essential.
