The flight began with a taxiing period from the parking to the runway, which took 5 minutes and covered less than 1 nautical mile. The aircraft, an Airbus A350-900, then departed from runway 20 at Nadi International Airport (NFFN). The takeoff distance was 1,693 meters, which accounted for 53% of the runway. The liftoff speed was 156 knots.

The local weather conditions at the time of departure were characterized by a temperature of 25 degrees Celsius, with a wind speed of 6 knots at 116 degrees. This resulted in a crosswind of 6 knots and a tailwind of 1 knot. The aircraft then began its enroute climb, starting 1 mile north of Nadi, and climbed from an altitude of 1,057 feet above sea level to 41,429 feet above sea level, an increase of 40,372 feet, in 11 minutes and covering 264 nautical miles.

The enroute level cruise phase began at a latitude of -21.3901867 and a longitude of 174.6064878, and lasted for 47 minutes, covering 1,320 nautical miles. The aircraft then started its enroute descent, beginning 99 miles southeast of Fingal Bay, Australia, and descended from 40,094 feet above sea level to 3,920 feet above sea level, a decrease of 36,174 feet, in 15 minutes and covering 131 nautical miles.

The aircraft then entered another level cruise phase, starting 10 miles southeast of Bundeena, Australia, and lasted for 2 minutes, covering 5 nautical miles. The enroute descent phase began 7 miles southeast of Bundeena, and the aircraft descended from 3,914 feet above sea level to 1,290 feet above sea level, a decrease of 2,624 feet, in 4 minutes and covering 10 nautical miles.

The final approach to runway 34L at Sydney Kingsford Smith International Airport (YSSY) was made from the south, heading 348.0 degrees at 4 nautical miles and 1,264 feet above ground level. The landing was made on runway 34L, which had a length of 3,885 meters. The threshold height was good, and the threshold speed was slightly above the target at 137 knots.

The touchdown distance was good at 422 meters, but the touchdown speed was a little fast at 136 knots. The touchdown rate was fair at -287 feet per minute. The runway touchdown position was slightly misaligned by 6.7 meters from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 11 degrees Celsius, with a wind speed of 7 knots at 329 degrees. This resulted in a crosswind of 2 knots and a headwind of 7 knots.

The total landing distance was 1,488 meters, which accounted for 38% of the runway. The runway rollout alignment was very good. The taxiing period from the runway to the parking took 2 minutes and covered less than 1 nautical mile. The total flight distance was 1,737 nautical miles, taking 87 minutes, and the aircraft used 24,194 kilograms of fuel.
