The flight began with a taxiing period from the parking to the runway, which took 11 minutes and covered a distance of 5 nautical miles. The aircraft, an Airbus A350-900, then departed from runway 01L at RJCC New Chitose Airport in Japan. The takeoff distance was 1,253 meters, which accounted for 42% of the runway. The liftoff speed was 159 knots, and the local weather conditions at the time of departure were a temperature of -3°C, with a wind speed of 3 knots at 19°.

As the aircraft climbed to a higher altitude, it began its enroute climb from 1,127 feet above sea level to 38,621 feet above sea level, an increase of 37,495 feet in just 9 minutes, covering a distance of 148 nautical miles. The climb started overhead RJCJ JASDF Chitose Air Base in Chitose, Hokkaido, Japan. Following the climb, the aircraft entered a level cruise phase, which lasted for 9 minutes and covered a distance of 204 nautical miles, starting 5 miles east of Ichinohe in Iwate, Japan.

The aircraft then began its enroute descent from 38,444 feet above sea level to 4,867 feet above sea level, a decrease of 33,577 feet in 18 minutes, covering a distance of 101 nautical miles. The descent started 9 miles north of Daigo in Ibaraki, Japan. After the initial descent, the aircraft entered another level cruise phase, which lasted for 7 minutes and covered a distance of 20 nautical miles, starting 2 miles west of Ohara in Chiba-ken, Japan.

The final descent phase began 3 miles south of Kisarazu in Chiba-ken, Japan, and the aircraft descended from 4,738 feet above sea level to 1,802 feet above sea level, a decrease of 2,936 feet in just 4 minutes, covering a distance of 11 nautical miles. The aircraft then began its final approach to runway 34L at RJTT Tokyo Haneda International Airport, flying from the southeast at a heading of 335.0°, 4 nautical miles from the runway and at an altitude of 1,751 feet above ground level.

The landing on runway 34L was completed at a speed of 123 knots, which was slightly above the target speed. The touchdown point was 545 meters beyond the touchdown zone, and the touchdown rate was very hard at -512 feet per minute. The runway touchdown position was also excessively misaligned by 42.9 meters from the centerline. The local weather conditions at the time of landing were a temperature of 3°C, with a wind speed of 11 knots at 360°.

The total landing distance was 2,214 meters, which accounted for 74% of the runway. The runway rollout alignment was also significantly misaligned by 41.7 meters from the centerline. After landing, the aircraft took 3 minutes to taxi to the parking area, covering a distance of less than 1 nautical mile. The total flight distance was 496 nautical miles, and the flight duration was 59 minutes, with a total fuel consumption of 8,097 kilograms.
