What Is the US No Fly List
The US no fly list is a government watchlist that restricts individuals from boarding commercial flights departing from, arriving in, or flying over United States airspace. The list is maintained by the Terrorist Screening Center, a multi-agency organization housed within the FBI. Airlines must check passenger names against the list before and during flights, and individuals who match a listing are denied boarding. The screening process applies to both domestic and international flights that touch US territory or are operated by US carriers.
As of the latest public reporting, the list contains tens of thousands of identities, though the exact number is classified. The US government does not publish a current count, but congressional and oversight references have cited figures in the range of 47,000 to 80,000 entries over the past decade. The list includes US citizens, lawful permanent residents, and foreign nationals. Being on the list does not imply criminal charges or a conviction; it means the individual is considered a potential threat to aviation security based on intelligence and watchlist criteria.
Who Gets Placed on the No Fly List
Placement is determined through a government screening process that uses intelligence information, terrorist watchlist data, and behavioral indicators. The Terrorist Screening Center consolidates data from multiple agencies, including the National Counterterrorism Center, the Department of Homeland Security, and the intelligence community. Names can be submitted by federal agencies, foreign partners, or derived from observed travel patterns and communications intercepts. There is no single public database that shows exactly who is currently on the list.
Individuals flagged on the list may include those who have been involved in terrorism-related activities, those who match the name or alias of a known suspect, or those identified through travel and association patterns. US citizens and green card holders have been placed on the list, sometimes due to name similarities or misidentification. The government has acknowledged errors in the past, and redress mechanisms exist for people who believe they are wrongly listed.

How to Appeal or Get Removed from the No Fly List
The Department of Homeland Security operates a redress program called DHS TRIP, which allows individuals who are wrongly flagged or experience repeated travel problems to submit a formal inquiry. Through DHS TRIP, travelers can request review of their status and provide identifying information to correct potential errors. The program is designed for people who are not known or suspected terrorists but experience secondary screenings, delays, or denials at airports.
While DHS TRIP does not guarantee removal, it provides a structured path for individuals to challenge their status. The redress process involves submitting personal data, travel history, and supporting documents to verify identity. In some cases, travelers who were misidentified due to name matches have been successfully removed after completing the process. For details on the redress process and related travel security rules, see the official DHS TRIP page here.
No Fly List and Airline Compliance
Airlines are legally required to check passenger names against the no fly list before boarding. The Transportation Security Administration sets the rules and enforces compliance, and carriers can face penalties for failing to follow the rules. Airlines use the Secure Flight program, which matches passenger information against the watchlist before check-in. The program is designed to reduce misidentifications by collecting more detailed passenger data, such as full name, date of birth, and gender.
The no fly list intersects with broader security measures used by companies in the aviation and travel technology sectors. For example, major carriers and travel platforms integrate watchlist screening into booking and check-in systems to meet federal requirements. For a related
