I called yesterday and they initially told me that they can clear the MNL-HKG-MNL sectors. Then got a follow up call that if I am willing to move my return sector from HND to NRT they may be able to open up a seat for "Diamond Members"
They also asked me to include my friend into my Redemption Group so that it would be easier for them to clear up the waitlist.

I wonder if they just put everyone on waitlist and wait for a DM to call them before they manually clear the redemptions on the system.
