Was nervous about this flight but honestly didn't need to be. Smooth the whole way, the 1h 40m went by fast.

First-time passenger · April

Did Siem Reap to Chiang Mai last July and it was genuinely one of the smoothest long-haul flights I've had. Barely any movement the whole way.

Frequent flyer · July

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