Most American airlines have their own mask mandates already in place, but enforcing them has been a problem. According to a Jan. 13 statement from the Federal Aviation Administration (FAA), there has been a “disturbing increase in incidents where airline passengers have disrupted flights with threatening or violent behavior,” which they say partly stems from passengers’ refusal to wear masks. But the Association of Flight Attendants-CWA says a mandate from the White House will help introduce a standard for U.S. airlines, as well as back up flight attendants and other airline workers who attempt to enforce face mask compliance.

Biden isn’t only requiring masks on airplanes, but as you travel through the airport, as well. After all, the CDC says this is where most of the risk of transmission lies when traveling by air. “Air travel often requires spending time in security lines and busy airport terminals,” the CDC notes, which increases a person’s potential exposure to COVID. Plus, an airport typically offers less air filtration and ventilation than an airplane itself.ae0fcc31ae342fd3a1346ebb1f342fcb In guidance directed toward bus transit operators, the CDC said that workers should wear masks, as well as “strongly encourage” passengers to use masks. The agency had attempted to mandate masks on buses in September of last year, according to The New York Times. However, the Trump administration reportedly blocked the agency from doing so. And for more on the virus’ spread, This Is How Bad the COVID Outbreak Is in Your State. A July study published in the journal Clinical Infectious Diseases found that the risk of COVID transmission on a train depended on where someone is sitting and how long they are traveling. It turns out, with windows not typically opening on trains, this mode of public transportation may be even riskier than buses due to lack of airflow. Fortunately, some major train companies, like Amtrak, have already mandated masks. But this order from Biden will enforce the usage of face coverings on all trains operating within the U.S. And for more up-to-date information, sign up for our daily newsletter. The last place masks will be mandated is on public maritime vessels, including ferries. Even though this mode of transportation is open air, the potential crowding is cause for concern. The CDC has long advised that maritime employees and travelers should “wear a face mask or cloth face covering when outside of individual cabins,” but the new mandate from the White House will now require it.
