The Airbus A320neo departed VTCC Chiang Mai International Airport on runway 36, executing a departure roll that required a takeoff distance of 1,374 m, representing 40 % of the runway. Liftoff was achieved at 155 kt. Ambient conditions were 17 °C with a wind of 1 kt from 270°, a cross-wind component of 1 kt and no head-wind.

Climb commenced one mile north-west of Chiang Mai, with the aircraft ascending from 2,015 ft asl to 29,000 ft asl, a gain of 26,985 ft achieved in 10 minutes while covering 56 nm.

The first cruise segment began 20 nm east of VTSD San Kamphaeng Airport and lasted 10 minutes, during which 69 nm were flown.

Descent started three miles west of Nan, dropping from 29,003 ft asl to 9,450 ft asl, a loss of 19,553 ft in 10 minutes over a distance of 68 nm.

A second cruise phase was initiated 15 nm north of Sainyabuli, lasting 3 minutes and covering 15 nm.

The next descent began 18 nm south-west of Luang Prabang, reducing altitude from 9,306 ft asl to 3,137 ft asl, a decrease of 6,170 ft in 5 minutes while traveling 21 nm.

A brief cruise followed, starting five miles south-west of Luang Prabang, lasting 2 minutes and spanning 6 nm.

Final approach to runway 05 at VLLB Luang Phabang International Airport involved a descent from 1,453 ft agl to 158 ft agl in 87 seconds, with the aircraft scoring on the stabilisation gates.

Landing on runway 05 was performed on a runway 2,496 m long; the threshold height at 112 ft agl was excessively over target and the threshold speed was well above target at 156 kt. Touchdown occurred 295 m beyond the touchdown zone, at a speed of 147 kt, with a very heavy touchdown rate of minus 724 fpm. Runway touchdown alignment was perfect. Local weather reported 15 °C, wind 1 kt from 270°, a cross-wind of 1 kt and a tail-wind component of 1 kt. Total landing distance measured 1,317 m, representing 53 % of the runway, and rollout alignment was perfect.

The aircraft taxied from the runway to parking in 3 minutes, covering less than 1 nm.

In total, the flight covered 243 nm, required 48 minutes of airborne time, and consumed 895 kg of fuel.
