The aircraft taxied from the parking area to runway 18L at KCVG Cincinnati Northern Kentucky International Airport, a movement that required 12 minutes and covered 1 nm.

During the departure roll on runway 18L, the Boeing 777-300ER used a takeoff distance of 1,898 m, representing 62 % of the runway, and achieved liftoff at 166 kt; ambient temperature was 21 °C with a wind of 3 kt from 200°, including a 1 kt cross-wind and a 2 kt head-wind component.

Climb commenced 1 mile southeast of KCVG, where the aircraft rose from 1,295 ft asl to 35,011 ft asl, an altitude gain of 33,716 ft achieved in 16 minutes while covering 105 nm.

The first cruise segment began 2 miles south of the 9OI5 Transportation Research Center of Ohio Airport and persisted for 323 minutes, during which 2,837 nm were flown.

A subsequent climb was initiated at latitude 55.0001755, longitude -14.0626917, raising the aircraft from 35,994 ft asl to 36,936 ft asl, a gain of 942 ft in 2 minutes over a distance of 15 nm.

The next cruise phase started at latitude 54.9452591, longitude -13.5909986 and lasted 49 minutes, covering 418 nm.

Descent began overhead Keele, Staffordshire, England, with the aircraft descending from 36,817 ft asl to 7,247 ft asl, a loss of 29,570 ft in 14 minutes while traversing 100 nm.

A brief cruise over Bovingdon, Hertfordshire, lasted 2 minutes and spanned 6 nm.

The following descent segment occurred over Watford, Hertfordshire, where altitude fell from 6,464 ft asl to 6,009 ft asl, a reduction of 455 ft in 2 minutes across 6 nm.

A short cruise segment 1 mile east of Edgware, Greater London, lasted 2 minutes and covered 5 nm.

Descent resumed over Crouch End, Greater London, with the aircraft dropping from 6,006 ft asl to 1,408 ft asl, a decrease of 4,597 ft in 5 minutes over 15 nm.

The final approach to runway 27R at EGLL London Heathrow Airport was executed from the east, heading 270.0° at 4 nm and 1,322 ft agl; the aircraft descended from 1,367 ft agl to 132 ft agl in 101 seconds and was scored on the stabilisation gates.

Landing on runway 27R, which measures 3,889 m, occurred with a threshold height of 78 ft agl and a threshold speed of 144 kt; touchdown was recorded 62 m beyond the touchdown zone at a speed of 144 kt, with a firm touchdown rate of minus 346 fpm and a lateral deviation of 7.5 m from the centreline. Local weather reported a temperature of 20 °C, wind 5 kt from 230°, a 3 kt cross-wind and a 4 kt head-wind. The total landing distance was 799 m, representing 21 % of the runway.

Runway rollout alignment was very good.

The aircraft taxied from the runway to the parking area in 8 minutes, covering less than 1 nm.

In total, the flight covered 3,520 nm, required 432 minutes of airborne time, and consumed 51,460 kg of fuel.
