Company Policy; Human Factors; Procedure
Approximately 2 hours after departure; we received a ZFW (Zero Fuel Weight) correction over ACARS. Our ZFW was actually 1000 pounds higher than reported prior to departure. Apparently; cargo was added just prior to pushback but did not get reported to LP. Our take-off data and performance calculations were based on the wrong ZFW.
[Report narrative contained no additional information.]
B737 flight crew reported receiving a second set of 'final' weights enroute.
