The TSA offers some information for transgender travelers on its website, including a note saying the agency is committed to ensuring transgender travelers are met with courtesy and respect.Burke relays that anyone wanting the assistance of a passenger support specialist at the security checkpoint can contact the TSA Cares helpline at (855) 787-2227 in advance. That hotline is also available for questions about screening policies, procedures and what to expect at a checkpoint. Travelers can also reach out to @AskTSA on Twitter for support.
If you feel you’ve been mistreated by the TSA, you can file a complaint on their site. The National Center for Transgender Equality also offers a comprehensive “Know Your Rights” toolkit for airport security.
