In february 2012 Korean Air seems to operate a two daily flights between  Seoul Incheon (ICN) and Honolulu. One of these flifgts is with a Boeing 747-400 and one with an Airbus A330-300. The duration of the flight is 7h 35 min with the Boeing 747-400 and 7h 50min with the Airbis A330-300. Both flights leave Seoul in the evening and arrive in Hololulu during the morning local time but the same day as you cross the international dateline from east to west during the flight.
