Frontier Airlines passenger arrested for hitting flight attendant with intercom phone.

A female passenger on Frontier Airlines Flight 708 departing from Denver became "belligerent" and was asked to deplane. As she was leaving, she hit a flight attendant with an intercom phone. The passenger was arrested, and the flight left for Tampa nearly four hours late. It's unclear what led to the initial request for the passenger to leave the plane. The incident is one of many reported cases of unruly passengers on flights this year.
