Frankfurt Airport (EDDF) served as the departure point for the Boeing 777‑300, where the aircraft taxiing from the parking area to runway 07C required 20 minutes and covered 3 nm. The takeoff roll measured 1,681 m, representing 42 % of the available runway, and the liftoff speed reached 192 kt. Local conditions at departure were 28 °C with a 4 kt wind from 50°, providing a 1 kt crosswind and a 3 kt headwind. Immediately after liftoff, the climb phase commenced over Frankfurt am Main, with the aircraft ascending from 1,286 ft ASL to 32,986 ft ASL—a gain of 31,700 ft achieved in 18 minutes while covering 123 nm.

The cruise segment began 1 mile southeast of Seybothenreuth, Bavaria, and extended for 570 minutes, during which 4,867 nm were traversed. Descent operations were initiated 18 miles northwest of VTV1 U‑Tong, Thailand, where the aircraft descended from 32,794 ft ASL to 11,180 ft ASL, a reduction of 21,614 ft in 14 minutes over 93 nm. Subsequent cruise and descent phases followed a similar pattern: a brief 3‑minute cruise covering 18 nm south‑west of Khlong Luang, a descent from 11,001 ft to 1,949 ft ASL over 36 nm north‑east of Bang Pa‑in, a 3‑minute cruise of 9 nm north‑east of Ban Lam Luk Ka, and a final descent from 1,769 ft to 932 ft ASL over 4 nm east of VTY9 Minburi, Bangkok. The approach to runway 20R at Suvarnabhumi Airport (VTBS) was executed from the north, with a heading of 195.0° at 4 nm and 922 ft AGL.

Landing on runway 20R, which measures 4,143 m, the aircraft touched down 65 m beyond the touchdown zone at a speed of 137 kt, slightly above the threshold speed of 139 kt. The touchdown rate was –190 fpm, and the runway alignment was maintained perfectly. The total landing distance was 2,037 m, accounting for 49 % of the runway length. Following the runway rollout, taxiing back to the parking area required 7 minutes and covered 2 nm. Overall, the flight covered 5,163 nm in 620 minutes, consuming 84,973 kg of fuel.
