Let $f:X->Y$ be an algebraic fiber space such that the general fiber has a good minimal model. We show that if $f$ is the Iitaka fibration then $X$ has a good minimal model. The result reduces the minimal model conjecture to the case of varieties of Kodaira dimension zero and the non-vanishing conjecture.
