We know turbulence can feel scary — especially on long flights. This report is built for you: what bumps feel like, when they happen, and why you'll be completely safe. 1 in 3 passengers feel exactly like you.
AI-powered flight briefing
15,500 data points analyzed · HIGH confidence
Your Flight

We analysed more than 15,500 data points along your route from Hong Kong International Airport to Bole International.

Your Journey Beta

1 hour, 3 hours 50 minutes, and 8 hours 20 minutes into the flight: Some moderate bumps expected.
The crew may adjust altitude or ask you to stay seated during these sections.
The rest of the flight should be smooth.

Your route takes you crossing the South China Sea, crossing the Bay of Bengal, and crossing the Arabian Sea – these areas can sometimes cause turbulence.

Smooth Flight

We're expecting smooth conditions throughout your flight. You can sit back and relax.

Takeoff

Takeoff should feel a bit bumpy initially, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 52 knots. These winds may delay arrival by up to 63 minutes.

Landing

Landing should feel smooth with possible light bumps with typical approach conditions.

You're in Safe Hands

If you feel nervous at any point, remember that turbulence is expected, safe, and part of normal flying. The crew is monitoring everything, and the aircraft is built to handle far more than anything you will feel. Have a safe and calm flight.

Tip
Afternoon flights may encounter more turbulence due to thermal activity as the sun heats the ground, creating rising air currents.
