I arrived in ANC on a United flight from SEA on Saturday night (2340 local) and noticed a Korean Airlines 744 and a Singapore Airlines 744 both parked away from the terminal. The SQ plane had a police car (well it looked like one with blue flashing lights) driving round and around the aircraft!! I couldn't find any mention of Anchorage in the timetable or schedules on www.singaporeair.com. I'm guessing it's a stopover en route to somewhere else.? Thanks!
