Really!? Professor. Jetstar the answer/saviour of the Qantas group. You've gotta be f$&@" joking. I'd rather fly Air Nambibia.
However VI, the punters would be flying QANTAS. Meaning, QANTAS would be flying internationally to DPS, NAN and HNL daily as examples. On the domestic front, Hamilton Island, Goldie multiple times a day, Newcastle, Avalon etc.
That was suggested on here years back as the ultimate goal. Fares would rise depending on the offering, e.g. QANTAS J class and not the joke that JQ calls business class - what you'd have though is yet more 'companies' the new International pilots company formerly JQ pilots, the new cabin crew company, formerly JQ crew etc.
It would be a reverse takeover though much like the Red and Blue tails from 1992, you'd have the Red and Orange tail staff.
However, how does that change the 'foreign investment % ?
