Interesting fare that I came across while searching around. CVG-ORD-HND-HKG-NRT-IAH-CVG for $999.46 and through United (17724 PQM) or $817 through calling ANA (returns a 7.6 cpm though cause of reduced mileage gains from fare class: approx. 7k less PQM through ANA).
Overnight layovers on both legs from Tokyo but same day turnaround in Hong Kong
Depart Monday, return Wednesday. Example fare
