I was wondering the same thing, Steve until I read about REX's investment deal with, you named it PAG, who are funding the airlines expanded domestic operations to the tune of $150m. Its full name is PAG Regulus Holdings Pte Ltd but I can't find what PAG stands for.
Therefore, forget the personalised initials on aircraft registration, such as the RM* or CZ* series and BZG, why not put the company who is funding REXs foray into capital city services on one of your newly acquired jets. Something a bit different. One day we might get registrations such as COM, NAB or STG when a deal is brokered, but only if the regos are available!
