We discuss the associated W{sup {+-}}H{sup {+-}} production at the CERN large hadron collider. The dependence of the hadronic cross section on the Higgs sector parameters is investigated in detail in the framework of the general two Higgs doublet model (THDM). We study the possible enhancement of the THDM prediction for the cross section compared to the prediction of the minimal supersymmetric standard model (MSSM). We find regions in the THDM parameter space where the THDM prediction can exceed the one of the MSSM by 2 orders of magnitude. These regions of large cross section are in agreement with theoretical bounds on the model, derived from the requirement of vacuum stability and perturbative unitarity, and are not excluded by experimental constraints.
