By analyzing an $e^+e^-$ annihilation data sample with an integrated luminosity of 2.93 fb-1 taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, we determine the absolute branching fractions of the hadronic decays $D^0$ → $K^+π^+ω, D^0$ → $$K^0_Sπ^0ω$$, and $D^+$ → $$K^0_Sπ^+ω$$ to be (3.392 ± 0.044stat ± 0.085syst)%, (0.848 ± 0.046stat ± 0.031syst)%, and (0.707 ± 0.041stat ± 0.029syst0%, respectively. The accuracy of the branching fraction measurement of the decay $D^0$ → $K^+π^+ω$ is improved by a factor of seven compared to the world average value. The $D^0$ → $$K^0_Sπ^0ω$$ and $D^+$ → $$K^0_Sπ^+ω$$ decays are observed for the first time.
