The authors present preliminary measurements of B meson decays to B{sup +} {yields} {omega}{pi}{sup +}, B{sup +} {yields} {omega}K{sup +}, and B{sup 0} {yields} {omega}K{sup 0}. The data were recorded with the BABAR detector and correspond to 88.9 x 10{sup 6} B{bar B} pairs produced in e{sup +}e{sup -} annihilation at the {Upsilon}(4S) resonance. They find statistically significant signals for all three channels: {Beta}(B{sup +} {yields} {omega}{pi}{sup +}) = (5.4 {+-} 1.0 {+-} 0.5) x 10{sup -6}, {Beta}(B{sup +} {yields} {omega}K{sup +}) = (5.0 {+-} 1.0 {+-} 0.4) x 10{sup -6}, and {Beta}(B{sup 0} {yields} {omega}K{sup 0}) = (5.3{sub -1.2}{sup +1.4} {+-} 0.5) x 10{sup -6}. They also measure time-integrated charge asymmetries {Alpha}{sub ch}(B{sup +} {yields} {omega}{pi}{sup +}) = 0.04 {+-} 0.17 {+-} 0.01 and {Alpha}{sub ch}(B{sup +} {yields} {omega}K{sup +}) = -0.05 {+-} 0.16 {+-} 0.01.
