The flight began with a taxiing period from the parking to the runway, which took 4 minutes and covered less than 1 nautical mile. The aircraft, an Airbus A350-900, then departed from runway 11R at VVNB Noi Bai International Airport in Hanoi, Vietnam. The takeoff distance was 986 meters, which accounted for 26% of the runway. The liftoff speed was 158 knots.

The local weather conditions at the time of departure were characterized by a temperature of 24 degrees Celsius, with a wind speed of 3 knots at 339 degrees. This resulted in a crosswind of 3 knots and a tailwind of 2 knots. The aircraft then began its enroute climb, which started overhead VVNB Noi Bai International Airport. The climb took 29 minutes and covered 200 nautical miles, during which the aircraft ascended from 1,085 feet above sea level to 38,619 feet above sea level, an increase of 37,534 feet.

Following the enroute climb, the aircraft entered a level cruise phase, which started 50 miles northeast of VVDH Dong Hoi in Vietnam. This phase lasted for 47 minutes and covered 373 nautical miles. The aircraft then began its enroute descent, which started 11 miles northwest of Huyen Lam Ha in Vietnam. The descent took 14 minutes and covered 91 nautical miles, during which the aircraft descended from 38,584 feet above sea level to 9,311 feet above sea level, a decrease of 29,273 feet.

The aircraft then entered another level cruise phase, which started 10 miles northeast of Thi Xa Phu My in Vietnam. This phase lasted for 5 minutes and covered 17 nautical miles. The aircraft then began its final descent, which started 9 miles west of Thi Xa Phu My. The descent took 8 minutes and covered 22 nautical miles, during which the aircraft descended from 9,316 feet above sea level to 1,312 feet above sea level, a decrease of 8,004 feet.

The final approach to runway 25R at VVTS Tan Son Nhat International Airport was made from the east, with a heading of 249.0 degrees at 4 nautical miles and 1,272 feet above ground level. The landing was made on runway 25R, which had a length of 3,043 meters. The threshold height was good, but the threshold speed was slightly above the target at 134 knots. The touchdown point was 112 meters beyond the touchdown zone, and the touchdown speed was a little fast at 134 knots. The touchdown rate was fair at -202 feet per minute.

The runway touchdown position was significantly misaligned by 24.1 meters from the centerline. The local weather conditions at the time of landing were characterized by a temperature of 25 degrees Celsius, with a wind speed of 5 knots at 330 degrees. This resulted in a crosswind of 5 knots and a headwind of 1 knot. The total landing distance was 1,465 meters, which accounted for 48% of the runway. The runway rollout alignment was misaligned by 22.6 meters from the centerline.

The taxiing period from the runway to the parking took 6 minutes and covered less than 1 nautical mile. The total flight distance was 710 nautical miles, which was covered in 115 minutes. The aircraft used 11,570 kilograms of fuel during the flight.
