On a JetBlue flight from the Dominican Republic to New York, a passenger refused to comply with instructions to wear a mask aboard the plane, threw an empty liquor bottle that almost hit another passenger, threw food and shouted obscenities at flight attendants, according to the F.A.A. The passenger grabbed the arm of a flight attendant and injured her arm. She struck the arm of another flight attendant more than once and scratched that crew member’s hand, causing the flight to return to the Dominican Republic, the F.A.A. said. FAA recommended a fine of $32,750 for the woman.
