Flew Hanoi–Fukuoka in April, had some light turbulence in the middle portion of the flight. Brief and nothing concerning. This route is usually fine.

Business traveler · April

Kids barely noticed the turbulence — just some mild bumps over Central Asia. Seatbelt sign was on and off a couple times. Nothing dramatic.

Parent traveling with kids · March

There was some noticeable movement over the subcontinent that made me grip the armrest. My seatmate (clearly a regular) didn't even look up from their book. Perspective.
