The Airbus A320neo departed VYYY Yangon International Airport on runway 21, using a take-off roll of 1,503 m which represented 44 % of the available runway. Liftoff was achieved at 166 kt. Ambient conditions were 17 °C with a wind of 1 kt from 270°, a cross-wind component of 1 kt and a head-wind component of 1 kt.

Climb commenced 2 nm south-west of VYYY, where the aircraft accelerated from 1,030 ft asl to 30,969 ft asl, gaining 29,939 ft in 11 minutes while covering 61 nm.

Cruise was segmented several times. The first level segment began 9 nm south-east of Thanatpin and lasted 12 minutes for a distance of 80 nm. A second cruise started 39 nm south-east of VTCS Mae Sariang Airport, lasting 2 minutes and covering 9 nm. The third cruise originated 26 nm south of Chom Thong, lasted 2 minutes and spanned 8 nm. The final cruise segment began 12 nm south of Pa Sang, persisted for 12 minutes and covered 54 nm.

Descent was also broken into four portions. The initial descent began 34 nm north-east of VYPA Hpa-N Airport, dropping from 31,001 ft asl to 19,063 ft asl - a loss of 11,938 ft in 5 minutes over 33 nm. The next descent started 34 nm south of Chom Thong, descending from 19,006 ft asl to 14,080 ft asl, a decrease of 4,925 ft in 2 minutes across 9 nm. A further descent commenced 21 nm south of Chom Thong, falling from 13,066 ft asl to 8,077 ft asl, a loss of 4,988 ft in 3 minutes while covering 16 nm. The final descent began 10 nm north of VTSI San Sai Airport, reducing altitude from 7,993 ft asl to 2,641 ft asl - a decrease of 5,352 ft in 5 minutes for 18 nm.

During final approach to runway 18 at VTCC Chiang Mai International Airport, the aircraft descended from 1,663 ft agl to 174 ft agl in 86 seconds and achieved the required stabilisation gate scores.

Landing on runway 18 was executed with a runway length of 3,112 m. The threshold height at 105 ft agl was noted as excessively over target and the threshold speed was well above target at 156 kt. Touchdown occurred 286 m beyond the touchdown zone, with a speed of 146 kt and a heavy touchdown rate of minus 660 fpm. Alignment at touchdown was very good. Local weather at the time was 15 °C with a wind of 1 kt from 270°, a cross-wind of 1 kt and no head-wind. Total landing distance measured 1,311 m, representing 42 % of the runway, and rollout alignment was perfect.

Rollout proceeded without deviation, maintaining the perfect alignment noted at touchdown.

Taxi-in to the parking area required 5 minutes and covered less than 1 nm.

In total, the flight covered 295 nm, required 62 minutes of airborne time and consumed 1,118 kg of fuel.
