U.S. to extend mask requirement on planes, buses and mass transit until April 18

U.S. officials are extending the requirement for masks on planes and public transportation for one more month through mid-April while taking steps that could lead to the rule being lifted.

The mask mandate was scheduled to expire March 18, but the U.S. Transportation Security Administration (TSA) said Thursday that it will extend the requirement through April 18.

TSA said the extra month will give the U.S. Centers for Disease Control and Prevention (CDC) time to develop new, more targeted policies that will consider the number of cases of COVID-19 nationally and in local communities, and the risk of new variants.

The TSA enforces the rule, which extends to planes, buses, trains and transit hubs.

As of Thursday, more than 98 per centof the U.S. population lived in areas with low or medium COVID-19 case levels, meaning that the CDC no longer recommends face masks in public indoor settings.

A decision to eventually scrap the mask requirement one of the last vestiges of nationwide pandemic rules has grown more likely in recent weeks as more states, even those led by Democratic governors, relaxed their own mandates for wearing masks indoors, and the CDC eased its recommendations.

Critics question policy

That led critics to question why the CDC would allow maskless people to gather in movie theatres and sports arenas but not on planes.

White House press secretary Jen Psaki said Thursday that deciding on the right policy for travel was more complicated than setting recommendations for local communities.

"If you're moving from one zone to another and picking people upit's a little bit different, and that requires some consultation, which is what (CDC officials) are going to endeavour to do between now and April 18," shesaid.

CDC Director Dr. Rochelle Walensky said last week that her agency must study the science around virus transmission "but also the epidemiology and the frequency that we may encounter a variant of concern or a variant of interest in our travel corridors."

U.S. Sen. Roger Wicker of Mississippi, the top Republican on the U.S. Senate Commerce, Science & Transportation Committee, said he was disappointed in the one-month extension.

"The science does not support this decision," he said. Earlier, Wicker and 30 other Republican senators asked U.S. President Joe Biden to end the mask rule and a requirement that travellers test negative forCOVID-19 within a day before flying to the U.S.

Pressure from travelindustry, too

Airlines for America, a trade group that represents the largest U.S. airlines, said in a statement that it urged the administration to end both rules.

Dr. Graham Snyder, medical director of infection prevention at the University of Pittsburgh Medical Center, said it makes sense to be more cautious on planes, subway trains and buses because "they are designed to efficiently put a lot of people in one place," raising the risk of virus transmission.

Stephen Morse, an infectious-diseases expert at Columbia University, said a short-term extension of the rule is appropriate, but he warned that once it is dropped it will be hard to revive if COVID-19 cases surge again.

He said there have been so many surprises with the pandemic that "a month may not be long enough."

The federal mask mandate was imposed in January 2021, days after Biden took office, and has been extended several times. TheTrump administration had declined to require masks on public transportation, but airlines began requiring them in mid-2020 to reassure passengers worried about contracting COVID-19.

Last September, the U.S. Transportation Security Administration doubled the fines for people who refused to wear a mask on public transportation up to $1,000 US for first-time offenders and up to $3,000 US for repeat violations.

The requirement became a lightning rod for confrontation between some passengers and airline crews. Since the start of 2021, airlines have reported more than 6,000 incidents of unruly passengers, most of them involving disputes over mask wearing.

That history could make it unlikely for airlines to require masks once the federal rule lapses.
