Passengers on American Airlines found themselves facing confusion and long delays on Wednesday after the carrier canceled more than 1,000 flights [1], 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.
