DALLAS -- American Airlines says passenger seats on a third flight came loose during flight and it's continuing to inspect other jets with similar seating.
American officials say that the loose seats are not an act of sabotage by angry workers.
The airline acknowledged Tuesday that seats came loose on a flight last week between Vail, Colo., and the Dallas-Fort Worth Airport. The same thing happened on a flight Saturday and another on Monday.
The planes involved in the Saturday and Monday incidents were recently worked on at an American Airlines maintenance base in Tulsa, Okla., and at a Timco Aviation Services facility in North Carolina. Timco has declined to comment.
