Narrative:

Last min baggage was loaded just prior to push back. A jump seat rider was on board which increased the maximum takeoff weight to a ramp weight to accommodate the weight of the jump seat rider. Both of these scenarios led to an overweight taxi weight by 225 pounds. Our company adds the weight of a jump seat rider to the maximum takeoff weight. The concept is the additional 180 pounds will be burnt out of the taxi fuel. We restricted the flight to baggage and passenger only but due to headwinds the flight required a maximum fuel load. I received a call from central load planning after gate departure advising me of an overweight takeoff weight problem. The takeoff weight wasn't the problem because the flight burned off 735 pounds of taxi fuel. The problem was a taxi weight of 119225 pounds, 225 pounds over maximum. This was caused by last min baggage and a policy to add the jump seat rider weight to the maximum takeoff weight and assume the aircraft will burn off the overage in taxi fuel.

Title: A B737-300 WAS DISPATCHED WITH THE MAX TAXI WT EXCEEDED.

Narrative: LAST MIN BAGGAGE WAS LOADED JUST PRIOR TO PUSH BACK. A JUMP SEAT RIDER WAS ON BOARD WHICH INCREASED THE MAX TKOF WT TO A RAMP WT TO ACCOMMODATE THE WT OF THE JUMP SEAT RIDER. BOTH OF THESE SCENARIOS LED TO AN OVERWT TAXI WT BY 225 LBS. OUR COMPANY ADDS THE WT OF A JUMP SEAT RIDER TO THE MAX TKOF WT. THE CONCEPT IS THE ADDITIONAL 180 LBS WILL BE BURNT OUT OF THE TAXI FUEL. WE RESTRICTED THE FLT TO BAGGAGE AND PAX ONLY BUT DUE TO HEADWINDS THE FLT REQUIRED A MAX FUEL LOAD. I RECEIVED A CALL FROM CENTRAL LOAD PLANNING AFTER GATE DEP ADVISING ME OF AN OVERWT TKOF WT PROB. THE TKOF WT WASN'T THE PROB BECAUSE THE FLT BURNED OFF 735 LBS OF TAXI FUEL. THE PROB WAS A TAXI WT OF 119225 LBS, 225 LBS OVER MAX. THIS WAS CAUSED BY LAST MIN BAGGAGE AND A POLICY TO ADD THE JUMP SEAT RIDER WT TO THE MAX TKOF WT AND ASSUME THE ACFT WILL BURN OFF THE OVERAGE IN TAXI FUEL.
