Beyond limiting the coronavirus’s flow from hot spots to the rest of the country, allowing only vaccinated people on domestic flights will change minds, too.
When you go to the airport, you see two kinds of security rules. Some apply equally to everyone; no one can carry weapons through the TSA checkpoint. But other protocols divide passengers into categories according to how much of a threat the government thinks they pose. If you submit to heightened scrutiny in advance, TSA PreCheck lets you go through security without taking off your shoes; a no-fly list keeps certain people off the plane entirely. Not everyone poses an equal threat. Rifling through the bags of every business traveler and patting down every preschooler and octogenarian would waste the TSA’s time and needlessly burden many passengers.
The same principle applies to limiting the spread of the coronavirus. The number of COVID-19 cases keeps growing, even though remarkably safe, effective vaccines are widely available, at least to adults. Many public agencies are responding by reimposing masking rules on everyone. But at this stage of the pandemic, tougher universal restrictions are not the solution to continuing viral spread. While flying, vaccinated people should no longer carry the burden for unvaccinated people. The White House has rejected a nationwide vaccine mandate—a sweeping suggestion that the Biden administration could not easily enact if it wanted to—but a no-fly list for unvaccinated adults is an obvious step that the federal government should take. It will help limit the risk of transmission at destinations where unvaccinated people travel—and, by setting norms that restrict certain privileges to vaccinated people, will also help raise the stagnant vaccination rates that are keeping both the economy and society from fully recovering.
