We report improved measurements of branching fractions for charmless hadronic two-body B meson decays containing an ω meson in the final state. The results are based on a data sample of 78 fb ^-1 collected on the Y(4S) resonance by the Belle detector. We measure the branching fractions B(B ⁺ → ωK ⁺)=(6.5 _-1.2 ^+1.3±0.6) × 10 ^-6 and B(B ⁺→ωπ ⁺=(5.7 _-1.3 ^+1.4±0.6)×10 ^-6. We give 90% confidence upper limits for B(B ⁰→ωK ⁰) ≤7.6×10 ^-6 and B(B ⁰→ωπ ⁰)<1. 9×10 ^-6. We also obtain the partial rate asymmetries A _CP=0.06 _-0.18 ^+0.21 ±0.01 for B ^±→ωK ^± and A _CP=0. 50 _-0.20 ^+0.23±0.02 for B ^±→ωπ ^±.
