UA just updated me in email:
United flight UA895 on January 19 is delayed due to airport conditions.
Now departs: 10:45 p.m. on January 19, Hong Kong (HKG)
Now arrives: 2:12 a.m. on January 20 at Singapore, Singapore (SIN)
Strange. According to Flightradar, the incoming leg from Chicago was on time (even a bit early), I myself landed in HKG a few minutes later and there was (is) no weather etc.
That leaves possible conditions at SIN, but looking http://www.flightstats.com/go/FlightStatus/flightStatusByAirport.do
lots of other flights there are on time..
Is there any other source one could look for what these 'airport conditions' might be (I gather the staff here at the lounge would not have details either)
