EDIT:
might not be bookable--seems to contradict fare rules. Ticket was confirmed, but is a BULK fare.
Tends to, but not always, involve a long layover in Tokyo.
I haven't had any luck getting it to appear on the NH/UA website or google flights, but is available through Kayak (Vayama); someone with more experience might be able to.
Seems to book into K or L fares, which should be 100% PQM on UA.
Examples:
$643 JFK-HKG 5/6-5/9
$603 JFK-HKG-EWR 5/7-5/10
$693 IAD-HKG 5/6-5/8
$657 DCA-HKG-IAD 5/7-5/10
Should be 17000-ish PQM.
