NEW YORK (AP) — American Airlines says a Boston to Miami flight had to make an emergency landing at JFK airport over the weekend due to a row of dislodged seats.

Flight 685 landed safety at Kennedy Airport on Saturday.

The unit of AMR Corp. said in a statement that passengers in the affected row were moved to three other seats.

Passengers aboard the flight were placed on another aircraft for the trip to Miami.

The airline said it was conducting an internal investigation to determine why the row of seats became loose.

It said the FAA was notified of the problem and the airline's internal review.
