Passengers on American Airlines found themselves facing confusion and long delays on Wednesday after the carrier canceled more than 1,000 flights, as its efforts to inspect and in some cases reattach wiring bundles in the wheel wells of its 300-plane fleet of MD-80s dragged on.

More cancellations are expected Thursday.

Oh, my... I do believe attached wiring bundles might be important, but what do I know. Glad I don't have a trip planned that requires a flight.
