Plans for those two aircraft being operated by DHK failed to materialise and, in plain English, DHL have no use of them in the European based fleet.
GDHLJ and LK (the two youngest in the fleet) will transition from DHK to GTI and operate out of PVG. Rumours have been floating SYD will be one of the destinations, replacing the CVG-HNL-SYD rotation currently operated by a CKS 744F, but that it is only a rumour. All that is known is they'll be Asia based, so it might as well be out of Honkers flying to ... who knows?
