Narrative:
Captain ordered additional fuel to be uploaded beyond the required 11500 pounds to 15000 pounds. He did not inform our dispatcher. He did get the new fuel slip and we departed the gate for the short flight, tri to taxi. Near the end of the runway, the ACARS presented the weight and balance data, which I transcribed to the required data points in the FMC. We completed our checklist and departed. On climb out the captain asked if the ACARS reflected the additional fuel. A check showed that it did not. We departed 3500 pounds heavier than the computer thought we were. We did use the recommended derate and assumed temperature and trim settings and departed uneventfully. By not informing the dispatcher of our additional fuel, we did not receive the amended release through ACARS which would have informed everyone in the loop of the additional weight. Because of the wide disparity in passenger loads and carry-on's and the small increase in fuel load, I don't feel we were ever in any danger.

Title: A B737-300 FLC CHANGES FUEL LOADING AT TRI AND FAILS TO NOTIFY DISPATCHER. FLC TAKES OFF WITH INCORRECT WT AND BAL.
Narrative: CAPT ORDERED ADDITIONAL FUEL TO BE UPLOADED BEYOND THE REQUIRED 11500 LBS TO 15000 LBS. HE DID NOT INFORM OUR DISPATCHER. HE DID GET THE NEW FUEL SLIP AND WE DEPARTED THE GATE FOR THE SHORT FLT, TRI TO TAXI. NEAR THE END OF THE RWY, THE ACARS PRESENTED THE WT AND BAL DATA, WHICH I TRANSCRIBED TO THE REQUIRED DATA POINTS IN THE FMC. WE COMPLETED OUR CHKLIST AND DEPARTED. ON CLBOUT THE CAPT ASKED IF THE ACARS REFLECTED THE ADDITIONAL FUEL. A CHK SHOWED THAT IT DID NOT. WE DEPARTED 3500 LBS HEAVIER THAN THE COMPUTER THOUGHT WE WERE. WE DID USE THE RECOMMENDED DERATE AND ASSUMED TEMP AND TRIM SETTINGS AND DEPARTED UNEVENTFULLY. BY NOT INFORMING THE DISPATCHER OF OUR ADDITIONAL FUEL, WE DID NOT RECEIVE THE AMENDED RELEASE THROUGH ACARS WHICH WOULD HAVE INFORMED EVERYONE IN THE LOOP OF THE ADDITIONAL WT. BECAUSE OF THE WIDE DISPARITY IN PAX LOADS AND CARRY-ON'S AND THE SMALL INCREASE IN FUEL LOAD, I DON'T FEEL WE WERE EVER IN ANY DANGER.
