Covid-19 Prevention on Flights: How To Avoid Getting Sick

Whether you’re traveling domestically or heading abroad, feeling your best at your destination means you’ll get the most out of your trip. Unfortunately, COVID-19 is still out there, and cases are expected to climb again as we head into the winter months. By now you’re likely aware of basic COVID prevention strategies, but air travel presents unique challenges that can be tricky to navigate.

Luckily, you can take steps to lower the odds of picking up the illness on your next flight. To help you do just that, we asked doctors and health policy researchers how they lower their COVID risk while flying. Here’s what they recommend.

Many of us know this already, but it’s worth recalling: Research has found that wearing a well-fitting, high-quality mask like an N95 or KN95 lowers your chances of picking up COVID-19 by 83%, according to the Centers for Disease Control and Prevention. But when you wear a mask during your travels matters, says William Schaffner, MD, an infectious disease specialist and professor at the Vanderbilt University School of Medicine.

“You really want to use your mask consistently around others, whether you’re in the airport or on that plane,” he says. Thomas A. Russo, MD, professor and chief of the Division of Infectious Diseases at the University at Buffalo’s medical school, agrees. “Think about the whole process when you fly—going through the airport, checking in, boarding the plane, and being on the plane—you’re going to interact with people from all parts of the world… There’s a risk you might get COVID,” he says.

You can help protect yourself by always keeping your mask on—and wearing a relatively new one. Compared to a mask that’s gotten a lot of use, a fresh one will fit more snugly around the nose, cheeks, and chin and, in turn, catch particles more effectively.

If you prefer not to wear a mask, you should take steps to protect yourself in other ways. For example, after you get to your seat, adjust the vent so the air blows over your face, suggests Sheldon H. Jacobson, PhD, a University of Illinois Urbana-Champaign professor and researcher whose work includes using data-driven risk assessments to inform public health policy.

Dr. Jacobson says most airplanes use high-efficiency particulate air (HEPA) filters that catch microbes. Plus, cabin air is refreshed every few minutes, and a good portion comes from outside the aircraft. As a result, what blows out of the vents is pretty fresh. This strategy also keeps the air around you moving faster, meaning there’s less time for you to inhale any possible germs in the cabin, according to Dr. Jacobson. Still, if the person sitting next to you is coughing and
