ST. PETERSBURG, Fla. (AP) - A federal judge in Florida struck down the national mask mandate covering airlines and other public transportation Monday, and the Biden administration said the rule would not be enforced while federal agencies decide how to respond to the judge's order.
The ruling appeared to free operators to make their own decisions about mask requirements, with several airlines announcing they would drop mandates but New York City's public transit system planning to keep one in place.
The Association of Flight Attendants, the nation's largest union of cabin crews, has recently taken a neutral position on the mask rule because its members are divided about the issue. On Monday, the union's president appealed for calm on planes and in airports.
"The last thing we need for workers on the frontlines or passengers traveling today is confusion and chaos," union leader Sara Nelson said.
Nelson said it takes airlines 24 to 48 hours to put new procedures in place and tell employees about them. She said passengers should check with airlines for updates about travel requirements.
The decision by U.S. District Judge Kathryn Kimball Mizelle in Tampa, an appointee of former President Donald Trump, also said the U.S. Centers for Disease Control and Prevention failed to justify its decision and did not follow proper rulemaking procedures that left it fatally flawed.
In her 59-page ruling, Mizelle said the only remedy was to vacate the rule entirely across the country because it would be impossible to end it for the limited group of people who objected in the lawsuit.
The judge said "a limited remedy would be no remedy at all" and courts have full authority to make a decision such as this - even if the CDC's goals in fighting the virus are laudable.
The Justice Department declined to comment when asked if it would seek an emergency stay to block the judge's order. The CDC also declined to comment.
The White House said the court ruling means that for now the mask order "is not in effect at this time."
"This is obviously a disappointing decision," White House press secretary Jen Psaki told reporters. "The CDC is recommending wearing a mask on public transit."
The CDC had recently extended the mask mandate, which was set to expire Monday, until May 3 to allow more time to study the BA.2 omicron subvariant of the coronavirus now responsible for the vast majority of cases in the U.S.
In New York, Metropolitan Transportation Authority communications director Tim Minton said the system was "continuing to follow CDC guidelines and will review the Florida court order."
The MTA operates New York City buses and subway trains as well as two commuter rail lines. Face coverings have been mandatory on all trains and buses since early in the pandemic.
United Airlines said in a statement that, effective immediately, masks would no longer be required on domestic flights or certain international flights.
"While this means that our employees are no longer required to wear a mask - and no longer have to enforce a mask requirement for most of the flying public - they will be able to wear masks if they choose to do so, as the CDC continues to strongly recommend wearing a mask on public transit," United said.
The federal mask requirement for travelers was the target of months of lobbying from the airlines, which sought to kill it. The carriers argued that effective air filters on modern planes make transmission of the virus during a flight highly unlikely. Republicans in Congress also fought to kill the mandate.
Critics have seized on the fact that states have rolled back rules requiring masks in restaurants, stores and other indoor settings, and yet COVID-19 cases have fallen sharply since the omicron variant peaked in mid-January.
There have been a series of violent incidents on aircraft that have mainly been attributed to disputes over the mask-wearing requirements.
The lawsuit was filed in July 2021 by two plaintiffs and the Health Freedom Defense Fund, described in the judge's order as a nonprofit group that "opposes laws and regulations that force individuals to submit to the administration of medical products, procedures and devices against their will."
Here in Pittsburgh, the airport released a statement, saying:
"Pittsburgh International Airport follows Transportation Security Administration rules and masks continue to be required in the terminal at this time. We are in contact with federal regulators should any changes occur," said Travis McNichols, senior vice president of Public Safety, Operations & Maintenance at Pittsburgh International Airport.
