Passenger Reports

Flew Colombo–Singapore 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

A few bumpy patches mid-flight, lasted maybe half an hour total. Drink service was paused briefly. Not unusual for this time of year.

Frequent flyer · March

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