Ahhhh TG - yet another one foot in the grave retired captain suffering from relevance deprevation syndrome.....
Your 'high up' contact in JQ is obviously your source for the information that as far as QF group profitability goes JQI is 'bringing home the bacon'
This is so far wrong it is laughable.
JQI has been destroyed in Japan and yield everywhere else, especially on those routes 'gifted' from mainline is through the floor also (see Hnl for example)
It may well be that more A330's are gifted to JQI.
So be it.
But be clear that this decision will be about ego, hubris and IR ideology driving a business decision, rather then cost or revenue benefit analysis.
