Apparently "Ally" recently presented to Alan and the EXCO detailed analysis of the loss of revenue caused of loss of seats on specific routes after the retirement of the 747 and replacement by 787 capacity.
She specifically highlighted JNB and HND. This presentation was based on work completed by the former head of strategy who was punted under similar circumstances - that is, he was in favour of expanding the Qantas mainline business. As long time followers / sufferers of QF know - having such a position inside the business is tantamount to corporate suicide under the current senior leadership.
Anyhow the overall theme of Ally's proposal was that Qantas needs to order more 787s and go firm or otherwise on the A350-1000 for project sunrise in order to remain competitive and to not give away any more market share to competitors.
This (unfortunately for Ally) goes against Alans overall scheme to 'gaslight' Qantas mainline capacity whilst still quietly growing JQ international and the JQ asian businesses.
As with what happened to Boston Bruce, she has been immediately rissholed from the company. She is already on 'gardening leave' and had her passes and access taken from her on the day she was fired by Alan.
