The flight began with a taxiing period from the parking to the runway, which took 9 minutes and covered a distance of 4 nautical miles. The aircraft, an Airbus A350-900, then departed from runway 07C at Hong Kong International Airport (VHHH). The takeoff distance was 42 meters, which is 1% of the runway length. The liftoff speed was 165 knots.

The local weather conditions at the time of departure were characterized by a temperature of 30 degrees Celsius, with a wind speed of 9 knots at 0 degrees. The crosswind was 9 knots, while the headwind was 3 knots. The aircraft then began its enroute climb, starting 1 mile northeast of Hong Kong International Airport, and climbed from an altitude of 1,008 feet above sea level to 41,563 feet above sea level, an increase of 40,555 feet, in 14 minutes and covering a distance of 194 nautical miles.

The enroute level cruise phase began at a location with a latitude of 19.0178054 and a longitude of 113.5586739, and lasted for 34 minutes, covering a distance of 1,062 nautical miles. The aircraft then started its enroute descent, beginning 53 miles northeast of Tioman Airport, and descended from 41,577 feet above sea level to 4,135 feet above sea level, a decrease of 37,442 feet, in 16 minutes and covering a distance of 137 nautical miles.

The aircraft then entered another level cruise phase, starting 5 miles east of Changi Air Base (East) in Singapore, and lasted for 2 minutes, covering a distance of 7 nautical miles. The enroute descent phase began 5 miles south of Changi Air Base (East), and the aircraft descended from 4,138 feet above sea level to 1,308 feet above sea level, a decrease of 2,829 feet, in 4 minutes and covering a distance of 5 nautical miles.

The final approach to runway 02C at Singapore Changi Airport (WSSS) was made from the south, with a heading of 23.0 degrees at an altitude of 1,280 feet above ground level, and a distance of 4 nautical miles from the runway threshold. The landing was made on runway 02C, which has a length of 4,022 meters. The threshold height was slightly above the target, and the threshold speed was also slightly above the target at 132 knots.

The touchdown point was 157 meters beyond the touchdown zone, and the touchdown speed was 129 knots, which was a little fast. The touchdown rate was fair at -221 feet per minute. The runway touchdown position was misaligned by 9.1 meters from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 32 degrees Celsius, with a wind speed of 6 knots at 329 degrees. The crosswind was 5 knots, while the headwind was 4 knots.

The total landing distance was 1,439 meters, which is 36% of the runway length. The runway rollout alignment was slightly misaligned by 8.6 meters from the centerline. The taxiing period from the runway to the parking took 3 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 1,417 nautical miles, and the flight duration was 84 minutes. The aircraft used 18,079 kilograms of fuel during the flight.
