Have you examined using AutoPkg to deploy AIR? In other words, skip AIR in the CCP pkgs, but use the AutoPkg-generated AIR installer for the AIR framework itself? Installing AIR inside CCP pkgs deployed by Munki can lead to unusual behavior, since Munki includes specific code to squash Adobe installer processes that are known to hang.
Join ##osx-server Internet Relay Chat (IRC) or email the munki-dev mailing list with questions, especially regarding Munki versus CCP. I have an Adobe-provided but unsupported workaround for installing DPS Desktop Tools for InDesign CC 2014--it might possibly help you as well.
