Federal Aviation Administration, FAA, says it is continuing to fine misbehaving passengers who do not abide by the rules.

The Associated Press reported FAA is pursuing civil penalties against two more such passengers for interfering with the airlines' crew.

The two of the recent cases involve a passenger who disobeyed to wear a mask which is mandatory according to federal law and another passenger who cursed the flight attendants and the airplane captain after boarding on the plane.

FAA said it has received more than  1,300 complaints of the passengers who misbehave on the plane and has also announced proposed civil penalties. Some of those penalties exceed $30,000. The passengers are given an option to protest against the penalties.

The fine announced against the passenger who refused to wear the mask is $10,500 and the one who cursed the crew is $9000.
