Aviation Security: TSA Should Assess Potential for Discrimination and Better Inform Passengers of the Complaint Process
Fast Facts
TSA—which screens over 1.5 million airline passengers daily—has faced allegations that some of its screening practices may negatively affect certain passengers.
Stakeholder groups and TSA officials said that TSA's advanced imaging technology and other practices could result in certain passengers—like people who are transgender, wear religious headwear, or have disabilities—being referred more frequently for additional screening. But TSA hasn't collected data on these referrals or assessed frequency. Also, stakeholders said that passengers are often unaware of how to file discrimination complaints.
We recommended TSA address these issues.
Highlights
What GAO Found
The Department of Homeland Security's (DHS) Transportation Security Administration (TSA) has taken actions, such as establishing procedures and training, that can help to prevent the potential for discrimination in its airline passenger screening practices. However, it has not assessed the extent to which these practices may result in certain passengers being referred for additional screening more often than others. For example, TSA officials in all four airports GAO visited and representatives from the seven stakeholder organizations GAO interviewed stated that TSA's advanced imaging technology or other practices could result in certain passengers being referred for additional screening more frequently than others. These include transgender passengers or those who wear religious headwear or have disabilities. TSA has not collected data on referrals for additional screening and conducted assessments to determine the extent to which this occurs. Such data collection and assessments could help TSA identify any actions needed to better comply with agency policies that prohibit discrimination.
Examples of TSA Passenger Screening Practices at Airport Checkpoints That Can Result in Referrals for Additional Screening
TSA has a process for addressing passenger complaints alleging discrimination, but could improve how it informs passengers about this process. For example, representatives from all seven stakeholder organizations stated that passengers are often unaware of how to file discrimination complaints. While TSA provides signs for airports to place at checkpoints that include contact information for questions about screening, most do not explicitly cite complaints. Taking additional steps to better inform the public about the discrimination complaint process could help ensure any issues are identified and addressed. Further, TSA's data systems and collection practices limit its ability to fully analyze discrimination complaints. For example, TSA is unable to analyze the number of complaints that were found to have merit or resulted in disciplinary actions because the data are stored in different systems that lack specific fields to collect this information. Improving TSA's analyses of discrimination complaint data could better inform training and other initiatives to help prevent discrimination.
Why GAO Did This Study
TSA screened over 1.5 million airline passengers per day in 2021 as part of its mission to protect the nation's transportation systems. However, TSA has faced allegations that some of its screening practices may negatively affect certain passengers and has received discrimination complaints.
GAO was asked to review the potential for discrimination in TSA's screening practices. This report addresses (1) how TSA helps ensure that its airline passenger screening practices do not result in discrimination and (2) the extent to which TSA has established and informed passengers about its complaint process for allegations of discrimination. GAO analyzed documents and data on TSA's screening practices and complaints process and interviewed TSA officials in headquarters and four airports, selected based on size, complaints filed, and other factors. GAO also interviewed seven stakeholder organizations, including those representing religious groups and persons with disabilities, selected based on their work on airline security screening.
Recommendations
GAO is making four recommendations to TSA to (1) collect data on passenger referrals for additional screening, (2) conduct assessments to determine the extent to which its screening practices comply with agency non-discrimination policies, (3) take additional actions to better inform passengers about its discrimination complaint process, and (4) strengthen its ability to analyze discrimination complaints. DHS concurred with these recommendations.
Recommendations for Executive Action
| Agency Affected | Recommendation | Status |
|---|---|---|
| Transportation Security Administration | The Administrator of TSA should collect additional data on passenger referrals for additional screening. (Recommendation 1) | In November 2022, we reported that TSA officials in all four airports we visited and representatives from the seven stakeholder organizations we interviewed stated that TSA's advanced imaging technology or other practices could result in certain passengers being referred for additional screening more frequently than others. However, we found that TSA had not collected data on referrals for additional screening to determine the extent to which this occurs. As a result, we recommended that TSA collect additional data on such referrals. According to TSA officials, the agency completed deployment of its new algorithm for advanced imaging technology machines in June 2023. The algorithm was... deployed to machines in about 340 airports. As mentioned in our report, this update was intended to increase detection rates and reduce false alarm rates for the traveling public, and also to remove the need for gender-identifying buttons on the machines. As a result of our recommendation, TSA collected data at about 20 selected airports from May 2023 through June 2023 during its fiscal year 2023 annual resource planning assessment to verify that the update is working as intended. TSA reported that approximately 27 percent of passengers received a pat-down when using the updated machines at the selected airports, compared to about 52 percent of passengers in the fiscal year 2022 assessment. As part of the fiscal year 2023 assessment, TSA also collected data using a new form that captures the processing time for passengers to complete the entire checkpoint security process. The form includes a field to identify passengers with disabilities, which according to TSA officials will allow the agency to conduct analysis to help improve screening for these individuals. For example, officials stated that the data collected can be used to compare the amount of time it took to screen passengers with and without disabilities, which may allow TSA to investigate the reasons for the differences and where in the screening process any issues occur. As a result of these actions to collect additional data on referrals for additional screening, TSA could better determine the extent to which its screening practices lead to more frequent additional screening for certain passengers. This in turn could inform TSA's assessments of compliance with its anti-discrimination policies and help TSA more proactively identify and prioritize possible improvements to technology, screening procedures, and training to mitigate the potential for discrimination against certain passengers.

| Transportation Security Administration | The Administrator of TSA should conduct assessments to determine the extent to which TSA's passenger screening practices comply with agency non-discrimination policies to identify any needed actions to improve compliance. (Recommendation 2) | As of August 2024, TSA officials stated that the agency plans to analyze the data collected on referrals for additional screening to identify the (1) rate that passengers alarm, (2) percentage of false alarms; and (3) causes of false alarms. They noted that the results of the analysis will be cross referenced with complaint data and used to identify whether there is a need to improve TSA security policies and procedures or to develop requirements for enhancements of security technology, including advanced imaging technology. In addition, TSA officials stated that new data collected as part of the agency's fiscal year 2023 annual resource planning assessment could be used to compare the...

| Transportation Security Administration | The Administrator of TSA should take additional actions to better inform passengers about TSA's discrimination complaint process. (Recommendation 3) | In November 2022, we found that the Transportation Security Administration (TSA) had taken limited steps to proactively inform passengers about their ability to file complaints, including those alleging discrimination, and the process for doing so. For example, TSA provided signs for airports to place at checkpoints that included general contact information for questions about airport security or assistance, but most of the signs did not specifically inform passengers about how to file complaints or the discrimination complaint process. In addition, representatives from all seven stakeholder organizations we interviewed stated that passengers are often unaware of how to file...

| Transportation Security Administration | The Administrator of TSA should strengthen TSA's ability to analyze passenger discrimination complaints, including improving the collection and tracking of complaints data, to help inform training, procedures, and other initiatives. (Recommendation 4) | In November 2022, we found that TSA's data systems and collection practices limited its ability to fully analyze complaints alleging discrimination in its airline passenger screening practices. For example, TSA was unable to analyze the number of complaints that were found to have merit because the data are stored in different systems that lack specific fields to collect this information. We recommended that TSA strengthen its ability to analyze passenger discrimination complaints, including improving the collection and tracking of complaints data. In response, in January 2025, TSA transitioned to a single, integrated case management system for customer service complaints. The intake,...
