There are both theoretical and experimental uncertainties in using data from cosmic-ray air showers to estimate hadronic cross sections above accelerator energies. We outline these problems and compare the physics used to extract {sigma}{sub pp}{sup tot} from air shower data to the widely used parametrization of the proton-proton cross section of Donnachie and Landshoff and other contemporary models. We conclude that the published cosmic-ray cross section values do not strongly constrain {sigma}{sub pp}{sup tot} fits from lower energy accelerator data. {copyright} {ital 1998} {ital The American Physical Society}
