An air passenger accused of repeatedly hitting her two young children on a Frontier Airlines flight was returned to jail after a brief hearing Friday.
The airline defended the way its crews handled the incident.
An FBI affidavit alleged that 38-year-old Tamera Jo Freeman hit and cursed at her children and assaulted and intimidated a flight attendant who intervened during a flight from San Francisco to Denver on Monday.
She was arrested when the plane landed plan and is being held for investigation of interference with a flight crew and assault on children.
A judge said she would remain in custody until another hearing next week.
Her 4-year-old daughter and 2-year-old son have been placed in the custody of family members in California.
Freeman's hometown wasn't released, and her court-appointed attorney, Martha Eskesen, declined to comment outside the courtroom Friday.
Freeman, a petite woman with long, light-brown hair, was shackled and wearing a gray and white jail uniform in court.
She sat silently beside Eskesen, who had been assigned the case earlier in the day.
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.
