Early in the coronavirus pandemic, air travel looked like a risky endeavor. Some scientists even worried that airplanes could be sites of superspreading events. For example, in March a Vietnamese businesswoman with a sore throat and a cough boarded a flight in London. Ten hours later, she landed in Hanoi, Vietnam; she infected 15 people on the flight, including more than half of the passengers sitting with her in business class.

Then in April, airlines shifted course. Many started to require passengers to wear masks on planes — and some airlines even enforced the policy. Just on Monday, the Centers for Disease Control and Prevention said it now “strongly recommends” all passengers and crew members wear masks.

So the big question is this: How well do the masks work? Do they make it safe to fly across the country for a family visit?
