This article addresses the issue of estimating the duration in inflation inbouncing cosmology when anisotropies, inevitably playing an important role, aretaken into account. It is shown that in Bianchi-I loop quantum cosmology, thehigher the shear, the shorter the period of inflation. In a range ofparameters, the probability distribution function of the duration of inflationis however peaked at values compatible with data, but not much higher. Thismakes the whole bounce/inflationary scenario consistent and phenomenologicallyappealing as all the information from the bounce might then not have been fullywashed out.
