Denver ? Flight crews appropriately handled a passenger accused of repeatedly hitting her two young children on a Frontier Airlines flight, a company spokesman said.

An FBI affidavit alleges that Tamera Jo Freeman, 38, hit and cursed at her 4-year-old daughter and 2-year-old son during a flight from San Francisco to Denver on Monday. It also alleges that she assaulted and intimidated a flight attendant who intervened.

Freeman was arrested after the plane landed and was held for investigation of interference with a flight crew and assault on children, both federal charges. A judge said at a brief hearing Friday in U.S. District Court that she would remain in custody until another hearing next week.

The FBI affidavit said Freeman told an investigator she “lost it” and slapped her children during the flight because they were fighting over the window shade and because her daughter had spilled a drink.
