QF uses the 77Ws to replace 744s to LAX and Asia and open up a few new routes in Asia. QF keeps enough 744ERs to do SCL, JHB and DFW and the rest. No idea what happens to the A380s that are freed up.
So that mean QF would have 12 A380's, 9 B744's, 6-10?? 777's? And then a handfull of A330's still doing asian routes. 4 types between about 35 frames?
