Former Assistant Secretary for Homeland Security under President Obama Juliette Kayyem called Tuesday for the Biden administration to restrict the unvaccinated from flying by placing them on a no-fly list

Flying is not a right, and the case for restricting it to vaccinated people is straightforward: The federal government is the sole entity that can regulate the terms and conditions of airline safety. And although air-filtration systems and mask requirements make transmission of the coronavirus unlikely during any given passenger flight, infected people can spread it when they leave the airport and take off their mask. The whole point of international-travel bans is to curb infections in the destination country; to protect itself, the United States still has many such restrictions in place. Beyond limiting the virus’s flow from hot spots to the rest of the country, allowing only vaccinated people on domestic flights will change minds, too.
