Narrative:

Operations called to advise me in dispatch of a weight mistake. Flight was loaded incorrectly. Apparently there were 2 pallets per operations that were supposed to be loaded on another flight that never made that flight. It was put on our flight and was not discovered until 20 mins after they were airborne. Operations and centralized load planning discovered flight took off 3238 pounds over maximum structural takeoff weight. I advised flight crew of the weight discrepancy and provided them to revised takeoff gross weights and zero fuel weights. Maintenance duty officer and maintenance flight duty manager were advised of the overweight discrepancy. Supplemental information from acn 689231: flight weight was actually about 11600 pounds less than what the crew received as final weight numbers.
