During the departure roll on runway 27R, the aircraft accelerated to a liftoff speed of 193 kt after traveling 1,965 m, which represented 51 % of the runway length; ambient temperature was 26 °C with a wind of 5 kt from 240°, including a 2 kt cross-wind and a 4 kt head-wind component.

The initial climb began over Harmondsworth, rising from 317 ft asl to 6,013 ft asl-a gain of 5,695 ft-in three minutes while traversing 12 nm.

Level cruise commenced over Cobham and continued for seven minutes, during which the aircraft covered 33 nm.

A subsequent climb segment started over Aylesford, climbing from 6,001 ft asl to 32,991 ft asl, an increase of 26,989 ft achieved in 19 minutes over a distance of 142 nm.

The next cruise phase originated one mile north-west of Gaasbeek, lasting 218 minutes and encompassing 1,832 nm.

Climbing again over Rustavi, the aircraft rose from 33,002 ft asl to 34,942 ft asl, gaining 1,940 ft in three minutes while covering 26 nm.

A further cruise segment began six miles north-east of Saloglu, persisting for 217 minutes and spanning 1,827 nm.

The final climb of the en-route portion started 91 mi south of Korla Licheng Airport, increasing altitude from 35,000 ft asl to 36,998 ft asl-a gain of 1,997 ft-in three minutes and covering 28 nm.

The last cruise leg was recorded at latitude 40.0851378, longitude 85.9620096, lasting 218 minutes and covering 1,896 nm.

Descent commenced three miles south of Daliang, with the aircraft descending from 37,003 ft asl to 1,316 ft asl, a loss of 35,687 ft in 22 minutes while traveling 115 nm.

The final approach to runway 07C at Hong Kong International Airport (VHHH) was flown from the south-west on a heading of 71.0° at 4 nm and 1,280 ft agl, followed by a further descent from 1,332 ft agl to 56 ft agl in 99 seconds, during which the aircraft met the stabilisation gate criteria.

Landing on runway 07C was executed with a threshold speed of 141 kt; touchdown occurred 198 m beyond the touchdown zone at a speed of 134 kt, with a vertical speed of minus 203 fpm and very good runway-centerline alignment, while local weather reported a temperature of 29 °C and a wind of 3 kt from 18°, including a 2 kt cross-wind and a 2 kt head-wind component.

The rollout covered a total landing distance of 1,648 m, representing 46 % of the runway length, and the aircraft maintained very good alignment throughout the ground roll.

After exiting the runway, the aircraft taxied to the parking area in two minutes, covering less than 1 nm.

In total, the flight covered 5,923 nm, required 721 minutes of elapsed time, and consumed 100,178 kg of fuel.
