Fly this route pretty regularly for work. Most of the time it's smooth — April was completely fine, not a bump worth mentioning.

Business traveler · April

Totally smooth October flight. The seatbelt sign came on once briefly mid-flight but nothing actually happened. Great trip.

Leisure traveler · October

Did Chiang Mai to Ho Chi Minh City last January and it was genuinely one of the smoothest long-haul flights I've had. Barely any movement the whole way.
