I'm not sure of the history of Soar after March 2015, however, up until then they were pretty much strictly RAAus. Once Neel got hold of an AOC (interesting story as to why he didn't get his own..), he started doing the odd charter flight in cross-hired aircraft. As far as I know, all TIFs were done under the RAAus banner....certainly this was the case up until March 2015.
