Multiple airlines allowing passengers to go maskless following judge's ruling

Multiple airlines have made mask-wearing optional for both passengers and employees following a judge's Monday ruling that struck down the Centers for Disease Control and Prevention's transit masking rules. Delta, United and American are among the carriers that will no longer require masks.

"Effective immediately, masks are optional for all airport employees, crew members and customers inside U.S. airports and onboard aircraft," Delta Air Lines said in a statement. Delta noted that the sudden nature of the ruling and the announcement from the Biden administration that the Transportation Security Agency would no longer enforce the mandate meant that passengers could experience "inconsistent enforcement during the next 24 hours."

"Remember to show understanding and patience with others who may not be aware enforcement is no longer required," the airline said.
