The flight began with a taxiing period from the parking to the runway, which took 8 minutes and covered a distance of 2 nautical miles. The aircraft, an Airbus A350-900, then departed from runway 04R at Nice-Côte d'Azur Airport, with a takeoff distance of 1,486 meters, which was 50% of the runway length. The liftoff speed was 156 knots.

The local weather conditions at the time of departure were characterized by a temperature of 19 degrees Celsius, with a wind speed of 6 knots from a direction of 200 degrees. This resulted in a crosswind of 3 knots and a tailwind of 5 knots. The aircraft then began its enroute climb, starting 1 mile southwest of Nice, and climbed from an altitude of 1,035 feet above sea level to 32,311 feet above sea level, an increase of 31,276 feet, in 18 minutes and covering a distance of 95 nautical miles.

After reaching the cruising altitude, the aircraft entered a level cruise, starting 1 mile south of the Campo di volo Ploia San Giuliano Vecchio in Italy, and lasted for 11 minutes, covering a distance of 83 nautical miles. The aircraft then began its enroute descent, starting 1 mile east of Lavertezzo in Switzerland, and descended from 31,751 feet above sea level to 10,692 feet above sea level, a decrease of 21,059 feet, in 15 minutes and covering a distance of 77 nautical miles.

The aircraft then entered another level cruise, starting overhead Ehrendingen in Switzerland, and lasted for 2 minutes, covering a distance of 7 nautical miles. The aircraft then began its final descent, starting 1 mile north of Bremgarten in Switzerland, and descended from 10,261 feet above sea level to 2,788 feet above sea level, a decrease of 7,472 feet, in 9 minutes and covering a distance of 10 nautical miles.

The final approach to runway 34 at Zürich Airport was made from the southeast, with a heading of 335.0 degrees at 4 nautical miles and 1,378 feet above ground level. The landing was made on runway 34, which had a length of 3,236 meters. The threshold height was good, and the threshold speed was also good at 130 knots. The touchdown distance was good at 115 meters, but the touchdown speed was a little fast at 131 knots. The touchdown rate was hard at -473 feet per minute, but the runway touchdown alignment was very good.

The local weather conditions at the time of landing were characterized by a temperature of 3 degrees Celsius, with a wind speed of 5 knots from a direction of 330 degrees. This resulted in a crosswind of 0 knots and a headwind of 5 knots. The total landing distance was 1,237 meters, which was 38% of the runway length. The runway rollout alignment was also very good.

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 281 nautical miles, and the flight duration was 66 minutes. The aircraft used a total of 6,745 kilograms of fuel during the flight.
