For anyone hurting for miles out of HKG, this is possible on the last weekend of the year. At 3.3cpm, quite acceptable for an EOY status run:
UA:$567 HKG-IAH 17127PQM 447PQD K-fare
Sat 30 Dec HKG-NRT-IAH
(17h35m overnight in IAH)
Sun 31 Dec IAH-ORD-HKG

HKG-NRT on NH, the remainder on UA metal.
Also possible to do as HKG-IAD with same departure/arrival dates.
UA:$556 HKG-IAD 16971PQM 447PQD K-fare

Or to EWR a day earlier
UA:$550 HKG-EWR 16566PQM 447PQD K-fare
Fri 29 Dec HKG-EWR
(15h30m overnight in EWR)
Sat 30 Dec EWR-ORD-HKG

All UA metal.
100% PQM on UA. A lot less elsewhere. From a winter weather point-of-view, IAH is the best choice.
