The Future?Speculation only!
The capacity now used for Fra is likely to be used for trans Pacific flying.Qf`s plan appears to be two fold....break the back of the unions by transferring much of the mainline business to lower cost subsidiaries(and expand the subsidiaries)Secondly develop the Asia/Pacific area where the majority of world growth in pax numbers will be over the next ten years.The 747.400 is the wrong aircraft type for this type of development(Except for states flying)Some of these aircraft may be transferred to AO over time.
The majority of flying done by QF Mainline over the coming years will be Asian and more than likely on 777 which is the more appropriate aircraft type
With SIA wanting to fly from East OZ to Westcoast US Qf will either open up another US port or increase frequencies(to LAX) with the capacity taken from FRA.
QF will fly only to LHR. All other flying to Europe will be done by AO or codeshare.All of this will require a reduction in Australian based cabin crew numbers.It will be a good time to be pilot(as the Qantas GROUP expands) but a bad time if you are mainline longhaul crew.Allowances and overtime will all be reduced as a result in the changes of the nature of flying.
This is speculation only on my part.It seems reasonable that things will pan out way this considering what has been going on lately.
