American Airlines says passenger seats on a third flight came loose as the plane was airborne Tuesday, and it's continuing to inspect other jets with similar seating. The airline acknowledged Tuesday that seats came loose on a flight last week from Dallas-Fort Worth International Airport to Vail, Colo., and the same thing happened aboard the same plane Monday and a second plane Saturday, according to the airline.
