On a national level, the Federal Aviation Administration (FAA) has issued a "zero tolerance" policy against disruptive behavior on commercial flights following a string of incidents around the insurrection at the U.S. Capitol building on Jan. 6.

For the time being, the FAA will not issue warning letters or negotiate penalties. Instead, the agency will act directly to issue fines of up to $35,000 and possible jail time for those who misbehave.
