This thread:

The issue has been resolved.
I had been dealing with a rookie supervisor in the Seattle office.
Yes, it appears as if there are some untrained supervisors at the NW elite
call center.
The NW Plat CSR I spoke to said there's a software glitch when you add
the Hawaiian AL portion to the routing. It needs to be overridden.
There's a need for more education in the booking of award trips to OZ.
The CSR today admitted that a lot of folks in the NW elite office are uncomfortable dealing with KAL, Malaysia, Air Tahiti Nui, and even Hawaiian.
Once again Schmutzig and Jaimito, thanks for the heads up. It's always
good advice to get a second opinion.
