Impact for NYC
EWR-HKG-SIN is around 22 hours. Faster than connecting in SFO. Problem is that for half the year the SIN-HKG-EWR is below minimum connect so without NRT it becomes a two stop, in which case the nonstop SIN-SFO-EWR is fastest. Hopefully UA will find a way to make SIN-HKG-EWR a year-round option. Not really sure why they haven't done in the past?
