Departing from Helsinki Vantaa Airport, the Airbus A321 began its journey on runway 22R, taking off with a liftoff speed of 158 kt after a 1,660 m takeoff distance, which covered 55% of the runway. The local weather conditions at the time of departure featured a temperature of 24 °C, with a wind speed of 11 kt at 279°, resulting in a 9 kt crosswind and a 7 kt headwind.

As the aircraft climbed to its enroute cruise altitude, it covered 137 nm in 15 minutes, increasing its altitude from 1,113 ft to 36,033 ft. The climb phase started 1 mile west of the departure airport and continued until the aircraft reached the enroute level cruise phase, which began 58 miles southeast of Mariehamn. The cruise phase lasted 29 minutes, during which the aircraft covered 767 nm. Following the cruise phase, the aircraft began its descent, which started overhead Gooik and lasted 15 minutes, covering 142 nm and decreasing its altitude from 35,974 ft to 1,680 ft.

The final approach to runway 27R at Charles de Gaulle International Airport was initiated from the east, with the aircraft heading 265.0° at 4 nm and 1,324 ft above ground level. The landing was executed with a threshold speed slightly above the target at 142 kt, and a touchdown distance of 349 m, which was within the acceptable range. However, the touchdown speed of 139 kt was a little fast, and the touchdown rate was firm at -383 fpm. The aircraft landed 4.1 m off the centreline, and the runway rollout alignment was also slightly misaligned by 9.8 m from the centreline. The total landing distance was 1,662 m, covering 62% of the runway. Following the landing, the aircraft taxied to the parking area, covering 2 nm in 7 minutes. The total flight distance was 1,056 nm, taking 74 minutes, and the aircraft used 6,945 kg of fuel during the flight.
