U.S. airline passengers who refuse to wear facial coverings during the novel coronavirus pandemic could have their flying privileges revoked, the industry's main lobby group said on Monday.
Major U.S. airlines may prevent anyone not wearing a mask from boarding and provide the coverings to passengers who have none. Once on board, however, flight attendants have little power to enforce the policy if passengers remove their masks.
Carriers with the policy include Alaska Airlines, American Airlines, Delta Air Lines, Hawaiian Airlines, JetBlue Airways, Southwest Airlines and United Airlines, Airlines for America said in a statement.
The airlines will clearly inform passengers about their individual policies on face coverings before flying, followed by an announcement with specific details onboard, it said.
Each carrier will determine the appropriate consequences for passengers who fail to comply, up to and including being put on that airline's no-fly list.
Airlines offer certain exemptions, including when people are eating or drinking.
United, which last week said passengers would have to agree to wearing a face covering on a pre-flight checklist, said any passenger that does not comply with the policy onboard beginning June 18 will be placed on an internal travel restriction list that would prevent them from flying with the airline "for a duration of time to be determined pending a comprehensive incident review."
Delta said it was doubling efforts to ensure customers are aware of, acknowledge and comply with its mask requirement, which it said is one of the most important ways to "stay safe while flying."
The measures are expected to remain in place throughout the coronavirus crisis.
On Twitter, Senator Ed Markey, who has been vocal along with about a dozen other Democratic senators on airline issues during the pandemic, praised the tougher enforcement policies, adding "But we still need federal action immediately."
The U.S. government has not mandated any airline safety requirements since the pandemic hit global aviation, despite calls from unions and industry.
"The federal government has completely abdicated its responsibility to keep the flying public and aviation workers safe during COVID-19," said Sara Nelson, president of the Association of Flight Attendant-CWA said, adding "the industry alone cannot fix this."
The administrator of the Federal Aviation Administration, Stephen Dickson, is expected to be questioned about masks at a Senate hearing on Wednesday.
