How about this suggestion? 2 airlines, 2 lists. KA guys go to the bottom of the CX list, and CX go to the bottom of the KA list. No one disadvantaged. The freighters are wet leased to CX, paint them whatever colour you want, no different to wet leasing 330s to the opposition CA at a loss is it? They could surely get creative with what deal they give themselves on the wet lease. The KA guys would then be flying CX schedules thus improving their productivity to the level that CX guys currently supposedly achieve. Whats wrong with this idea? The cost savings alone in not buying new hats for the freighter boys has to be attractive to the bean counters! All it would take is for the AOA to agree to let freight out of Manchester to be wet leased, come up with a cap on the size of the wet lease fleet, limit it to freight ops only, and voilą! A win win agreement.
This protects KA fast commands for KA fos, and CX tardy commands for CX guys.
If they say it is too expensive to maintain 2 lists, ask them to quote a price, then offer for the DPA and AOA to do it for them for half that figure!
They would then be negligent to the shareholders not to accept such a massive cost reduction to a previously inhibitive cost.
