The flight began with a taxiing period from the parking to the runway, which took 11 minutes and covered a distance of 3 nautical miles. The aircraft, an Airbus A350-900, then departed from runway 27L at Charles de Gaulle International Airport (LFPG) in France. The takeoff distance was 1,083 meters, which accounted for 30% of the runway. The liftoff speed was 167 knots.

The local weather conditions at the time of departure were characterized by a temperature of 16°C, with a wind speed of 15 knots blowing from a direction of 260°. This resulted in a crosswind of 1 knot and a headwind of 15 knots. The aircraft then began its enroute climb, starting 1 mile north of Roissy-en-France, and climbed from an altitude of 1,403 feet above sea level to 34,274 feet above sea level, an increase of 32,871 feet, in 17 minutes and covering a distance of 86 nautical miles.

The enroute level cruise started overhead Clemont, France, and lasted for 16 minutes, covering a distance of 244 nautical miles. The aircraft then began its enroute descent, starting 3 miles northwest of Babeau, France, and descended from an altitude of 34,623 feet above sea level to 4,042 feet above sea level, a decrease of 30,582 feet, in 23 minutes and covering a distance of 124 nautical miles.

The aircraft then entered another enroute level cruise, starting 5 miles southeast of Vilassar de Mar, Spain, and lasted for 2 minutes, covering a distance of 6 nautical miles. The final enroute descent started 4 miles southeast of el Besos i el Maresme, Spain, and descended from an altitude of 3,484 feet above sea level to 1,296 feet above sea level, a decrease of 2,188 feet, in 2 minutes and covering a distance of 7 nautical miles.

The final approach to runway 24R at Josep Tarradellas Barcelona-El Prat Airport (LEBL) was made from the northeast, heading 246.0°, at an altitude of 1,273 feet above ground level and a distance of 4 nautical miles from the runway. The landing was made on runway 24R, which had a length of 2,914 meters. The threshold height was good, and the threshold speed was slightly above the target at 133 knots.

The touchdown point was 265 meters beyond the touchdown zone, and the touchdown speed was 124 knots, which was a little fast. However, the touchdown rate was good at -182 feet per minute, and the runway touchdown alignment was very good. The local weather conditions at the time of landing were characterized by a temperature of 18°C, with a wind speed of 6 knots blowing from a direction of 100°. This resulted in a crosswind of 3 knots and a tailwind of 5 knots.

The total landing distance was 1,433 meters, which accounted for 49% of the runway. The runway rollout alignment was perfect. The taxiing period from the runway to the parking took 4 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 475 nautical miles, and the flight duration was 72 minutes. The aircraft used 8,740 kilograms of fuel during the flight.
