Firstly I currently work for DJ but have also worked for QF. I have also flown on all the jet carriers in OZ on many occasions and have to say that as percentages go, DJ gets the gong.
$ for $, DJ provides an all round better atmosphere irrespactive of the type of tube you are in, length of flight or cabin zone.
I think for the average punter and above (Frequent Flyer, Business types and those with a few more $$ to spend) then DJ is the obvious choice.
Having 3 classes will provide an even wider choice for all demographics in this country and in this fair land, freedom of choice is gold.
No bias in my post as I believe all jet carriers in Oz have their merits but rolling all the choices into one carrier is a winner when you combine our Flair, Fun and Freedom to choose...
