It is not just the LHWD regarding LOFO. It is the Integration Agreement and the Shorthaul Agreement that must be taken into account by FWA.
Whilst I think LOFO would be adhered to within the LHWD, particularly when it reduces to just Airbus to Airbus training, I really cannot see that in the worst case where QF withdraws completely from International Ops, that 80% or so of 737 pilots would be made redundant to accommodate redundant senior longhaul pilots.
