American Airlines is rushing to complete wiring repairs on a group of A300 jets, but this time the carrier is not canceling any flights, the Wall Street Journal reported on Thursday.

Mechanics have done maintenance work on some of American's A300s, but Federal Aviation Administration managers approved an alternate timetable under which the airline can keep flying those planes while it slowly fixes them, the report said.

The work is being done overnight at American's hub at New York's John F. Kennedy Airport, the Journal said.

American grounded more than 3,000 flights last month over problems with wiring systems on MD-80 planes, leaving over 300,000 passengers stranded.
