TSA Cares is a toll-free helpline for passengers with disabilities and medical conditions, providing information to those who need extra assistance before traveling. The Transportation Security Administration (TSA) recommends that you call before coming to the airport (about 72 hours) to learn what to expect when you arrive at the airport security checkpoint. Their representative will answer your questions about security policies and procedures and may coordinate with a TSA Customer Service Manager to assist you when you arrive at the airport.
Air travelers with disabilities and medical conditions, as well as their family members or travel companions, can call TSA Cares at 1-855-787-2227, Monday through Friday, 8 am to 11 pm, and weekends and holidays from 9 am to 8 pm Eastern Time. Travelers who are deaf or hard of hearing can use a relay service to contact TSA Cares or can e-mail TSA-ContactCenter@dhs.gov.
