B.O. or terror threat.

An American Airlines flight bound for Dallas-Fort Worth was diverted in Nashville Monday after passengers reported smelling burning matches.

Airport officials had 99 passengers and five crew members disembark the plane after it landed around 6:40 a.m. Monday.

The plane, which was en route from Reagan National Airport in Washington, was searched and luggage was screened.

Matches were found in the seat of one passenger, who was detained and questioned by the FBI. The matches were safety matches allowed in carry-on luggage under Transportation Security Administration rules.

Airport officials said the woman, who was not identified, was trying to conceal body odor.

She was released without being charged, but was not allowed back on an American Airlines flight.

The remaining passengers were screened, and the plane resumed its flight four hours later.

I guess they should stop giving away the peanuts then.
