Passenger Reports

I always expect the worst on longer flights but this one surprised me. Very little turbulence, only a few small bumps on descent. Manageable even for me.

Nervous flyer · April

Totally smooth August flight. The seatbelt sign came on once briefly over the subcontinent but nothing actually happened. Great trip.

Leisure traveler · August

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