Four 747s freighters will be leaving in 2016 as they were sold to Boeing in 2013 as part of a package of 6 aircraft, the remaining 747 pax airframes will also be retired this year. Three A340s leave this year, three KA A330s are being returned to the lessor to be replaced by three A330s that are owned by CX.
Next year the first two 777-300ER leases expire, the remaining A340s go, two more freighters go, and another two leased A330s leave KA.
KA cannot fly the aircraft they have let alone handle more, every CX aircraft does at least 50% more flying a day. KA is not the solution, they are part of the problem, their pilots never fly at night and that is were all the available slots are at HKIA.
Air Hong Kong also has very low productivity rates, those aircraft only average around 4 hours a day. The other problem with Air Hong Kong is that is not 100% owned by CX and has contractual limits on what other cargo it may carry.
CX has the most productive aircraft and crew in the group by a significant margin.
