We present an analysis of two-body B decays with a pseudoscalar (P) and an axial-vector meson (A) in the final state using factorization. We employ as inputs a limited number of experimental data, i.e. results for the B{yields}K{sub 1}{gamma}, and B{yields}K*{gamma} radiative decays and the branching ratios for B{yields}{pi}{rho}, {pi}K*, K{rho}, K{pi} nonleptonic decays. In this way we are able to compare our predictions with recent data from the Belle and BABAR collaborations on B{yields}a{sub 1}{pi} and make predictions on several other B{yields}PA decay channels, which might be used as a guide for experimental researches and as tests of factorization.
