The flight began with a taxiing period from the parking to the runway, which took approximately 3 minutes and covered less than 1 nautical mile. The aircraft, an Airbus A350-900, then departed from runway 34 at Zakynthos International Airport Dionysios Solomos. The takeoff distance was 735 meters, which is 40% of the runway length. The liftoff speed was 151 knots, and the local weather conditions at the time of departure were a temperature of 34 degrees Celsius and a wind speed of 9 knots from a direction of 340 degrees.

The crosswind component was minimal at 1 knot, while the headwind component was 9 knots. As the aircraft took off, it began its enroute climb, which started overhead Ambelokipoi in the Ionian Islands, Greece. The climb took 11 minutes and covered a distance of 24 nautical miles, during which the aircraft ascended from an altitude of 1,055 feet above sea level to 23,476 feet above sea level, an increase of 22,422 feet.

Following the enroute climb, the aircraft entered a level cruise phase, which started 8 miles east of Poros in the Ionian Islands, Greece. This phase lasted for 11 minutes and covered a distance of 69 nautical miles. The aircraft then began its enroute descent, which started 1 mile northwest of Kandila in the Peloponnese, Greece. The descent took 18 minutes and covered a distance of 72 nautical miles, during which the aircraft descended from an altitude of 23,529 feet above sea level to 1,552 feet above sea level, a decrease of 21,977 feet.

The final approach to runway 03L at Athens Eleftherios Venizelos International Airport was made from the southwest, with a heading of 37.0 degrees at a distance of 4 nautical miles and an altitude of 1,267 feet above ground level. The landing was made on runway 03L, which has a length of 3,202 meters. The threshold height was good, and the threshold speed was well above the target speed at 142 knots.

The touchdown point was 138 meters beyond the touchdown zone, and the touchdown speed was 132 knots, which was faster than the target speed. However, the touchdown rate was good at -179 feet per minute. The runway touchdown position was slightly misaligned from the centerline by 4.1 meters. The local weather conditions at the time of landing were a temperature of 29 degrees Celsius and a wind speed of 21 knots from a direction of 20 degrees. The crosswind component was 6 knots, while the headwind component was 20 knots.

The total landing distance was 1,135 meters, which is 35% of the runway length. The runway rollout alignment was very good. After landing, the aircraft taxied to the parking area, which took approximately 3 minutes and covered less than 1 nautical mile. The total flight distance was 173 nautical miles, and the flight duration was 49 minutes. The aircraft used a total of 5,525 kilograms of fuel during the flight.
