Found a good mileage deal on UA to Cebu, Philippines from seemingly everywhere I tried. Fares are high $700's to $800's with travel from now to April-ish

Fare requires overnight connection in HKG, 5 day min travel. After this flight, not sure if you would be sane if you flew back right away. Not sure about stopovers. All flights are UA metal except for HKG-CEB. Visa is not required for US passport holders.

Hard to price it on ITA, but easily available on UA's website
