OJM/OEB have to go in late 2017.
Even with the 'refresh'
they still have SkyBed Mk I (the sloper) in Business (if you miss out on old First)
and the crappy tiny fragile continually needs to be reset Rockwell Collins IFE system.
Can't see Qantas replacing seats/IFE, so its a pretty average passenger experience if you end up on one
OJS/OJT/OJU have a consistent product with the younger 6 744ERs so could well be kept beyond the arrival of the 787s
