The cancellations started Tuesday when the nation's largest airline yanked 300 planes out of service to bring them up to federal safety standards on wrapping electrical wires to prevent fires.
The airline's mechanics and FAA inspectors cleared more of the planes to return to service today. American says 226 of its MD-80s were back in service by this morning, and it expects the rest to be ready by tomorrow night.
American thought it had done the needed repair work two weeks ago, when it scrubbed more than 400 flights. But the Federal Aviation Administration said wiring still wasn't properly secured and stowed in wheel wells.
