Your reply makes it sound like that lift is unimportant... but it is
actually extremely important from a design point of view. First of
all, a 10% reduction in lift would make a large dent in payload
(>20%).  Second, the fuselage lift is virtually stall-proof and needs
to be considered in recovery from unusual attitudes (particularly on
something like an MD80 with all that fuselage in front of the CG).
