First Amendment Activities at Sea-tac
First Amendment Activities such as distribution of literature, charitable solicitation and expressions of opinions and ideas are allowed on Airport premises subject to certain regulations. A permit is required for most activities.
Seattle-Tacoma International Airport is a welcoming facility that serves the people of King County, passengers and employees who work at the airport. The Port respects the rights of individuals and peaceful groups to voice their views and has long worked with advocacy and nonprofit organizations to accommodate permitted demonstrations and other First Amendment Activities.
The Port of Seattle has put together a contingency plan for how we will manage spontaneous demonstrations at Sea-Tac. Demonstrators will be directed to an outside location away from airport operations. The Port remains committed to close communications with local nonprofits and advocacy groups to respect First Amendment Rights while protecting security at the airport.To learn more about First Amendment Activities (click blue highlighted words to download documents):
