Given its last on, first off, redundancy is relatively cheap
With pilots of all ranks and fleets spread out all over the seniority list, the retraining and redundancy costs would be through the roof if Last on, First Off occurred, and after all the reduction in numbers processes that would happen.
Far cheaper for more leave without pay, so you'd except QF to start pushing it's excess pilots to EK, JQ and the like with negotiated LWOP deals.
Aren't EK screaming for airbus rated pilots?
