Narrative:

During the leg from ZOA to sfo following a WX divert, ZOA operations failed to finalize the numbers in the computer prior to our departure, which led them to believe that we had departed without obtaining the proper weight and balance figures. Since we were not allowed to deplane passenger, we obtained the planned weight manifest from ZOA operations during the preflight phase, and fueled to the amount shown on the flight plan and the planned weight manifest. We had the final numbers to depart -- nothing could have changed. Unfortunately, what I failed to realize is that when the load planner closes out the flight with the 'final weights,' the report automatically sends the final numbers to the company computer on the aircraft. We discussed it prior to departure, that we hadn't received the numbers yet, when I believed that we had the final numbers and that operations just probably forgot to send them. After airborne, ZOA discovered that we had left and called dispatch to report that we had departed without final weights. It's a technicality that I failed to realize, but did not compromise safety of flight.

Title: FLT CREW OF B735 DEPARTED WITHOUT OBTAINING FINAL WEIGHT MANIFEST NUMBERS FROM LOAD PLANNING. FLT WAS IRREGULAR OP AFTER A WX DIVERSION.

Narrative: DURING THE LEG FROM ZOA TO SFO FOLLOWING A WX DIVERT, ZOA OPS FAILED TO FINALIZE THE NUMBERS IN THE COMPUTER PRIOR TO OUR DEP, WHICH LED THEM TO BELIEVE THAT WE HAD DEPARTED WITHOUT OBTAINING THE PROPER WEIGHT AND BALANCE FIGURES. SINCE WE WERE NOT ALLOWED TO DEPLANE PAX, WE OBTAINED THE PLANNED WEIGHT MANIFEST FROM ZOA OPS DURING THE PREFLT PHASE, AND FUELED TO THE AMOUNT SHOWN ON THE FLT PLAN AND THE PLANNED WEIGHT MANIFEST. WE HAD THE FINAL NUMBERS TO DEPART -- NOTHING COULD HAVE CHANGED. UNFORTUNATELY, WHAT I FAILED TO REALIZE IS THAT WHEN THE LOAD PLANNER CLOSES OUT THE FLT WITH THE 'FINAL WEIGHTS,' THE RPT AUTOMATICALLY SENDS THE FINAL NUMBERS TO THE COMPANY COMPUTER ON THE ACFT. WE DISCUSSED IT PRIOR TO DEP, THAT WE HADN'T RECEIVED THE NUMBERS YET, WHEN I BELIEVED THAT WE HAD THE FINAL NUMBERS AND THAT OPS JUST PROBABLY FORGOT TO SEND THEM. AFTER AIRBORNE, ZOA DISCOVERED THAT WE HAD LEFT AND CALLED DISPATCH TO RPT THAT WE HAD DEPARTED WITHOUT FINAL WEIGHTS. IT'S A TECHNICALITY THAT I FAILED TO REALIZE, BUT DID NOT COMPROMISE SAFETY OF FLT.
