The flight began with a taxiing period from the parking to the runway, which took 30 minutes and covered a distance of 12 nautical miles. The aircraft, an Airbus A350-900, then departed from runway 34R at RJTT Tokyo Haneda International Airport. The takeoff distance was 1,517 meters, which accounted for 51% of the runway. The liftoff speed was 172 knots.

The local weather conditions at the time of departure were characterized by a temperature of 12 degrees Celsius and a wind speed of 11 knots at a direction of 320 degrees. The crosswind component was 2 knots, while the headwind component was 11 knots. The aircraft then began its enroute climb, starting 1 mile north of RJTT Tokyo Haneda International Airport. The climb took 15 minutes and covered a distance of 171 nautical miles, during which the aircraft ascended from 1,044 feet above sea level to 39,627 feet above sea level, an increase of 38,583 feet.

Following the enroute climb, the aircraft entered a level cruise phase, which started 2 miles northwest of Higashine, Japan. This phase lasted for 11 minutes and covered a distance of 129 nautical miles. The aircraft then began its enroute descent, starting 14 miles southeast of RJSA Aomori Airport. The descent took 21 minutes and covered a distance of 121 nautical miles, during which the aircraft descended from 39,376 feet above sea level to 2,866 feet above sea level, a decrease of 36,510 feet.

The aircraft then entered another level cruise phase, which started 8 miles southeast of Tomakomai, Japan. This phase lasted for 2 minutes and covered a distance of 4 nautical miles. The aircraft then began its final descent, starting 5 miles east of Tomakomai. The descent took 3 minutes and covered a distance of 5 nautical miles, during which the aircraft descended from 2,832 feet above sea level to 1,350 feet above sea level, a decrease of 1,482 feet.

The final approach to runway 01R at RJCC New Chitose Airport was made from the south, with the aircraft heading 353.0 degrees at an altitude of 1,262 feet above ground level and a distance of 4 nautical miles from the runway. The landing was made on runway 01R, which had a length of 2,989 meters. The threshold height was good, but the threshold speed was slightly above the target at 139 knots.

The touchdown point was 295 meters beyond the touchdown zone, and the touchdown speed was 127 knots, which was a little fast. The touchdown rate was heavy at -690 feet per minute. The runway touchdown alignment was perfect, but the runway rollout alignment was misaligned by 22.5 meters from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 2 degrees Celsius and a wind speed of 30 knots at a direction of 320 degrees. The crosswind component was 16 knots, while the headwind component was 26 knots.

The total landing distance was 1,131 meters, which accounted for 38% of the runway. The taxiing period from the runway to the parking took 5 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 449 nautical miles, and the flight duration was 73 minutes. The aircraft used 7,639 kilograms of fuel during the flight.
