Your Journey Beta

3 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, across the Thar Desert, and crossing the Persian Gulf – 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 smooth with possible light bumps, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 84 knots. These winds may delay arrival by up to 105 minutes.

Landing

Landing should feel a bit bumpy on descent 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.

Data Sources & Our Approach
ZeroTurb's Custom Algorithm: We've developed a proprietary ZeroTurb Index (ZTI) algorithm that combines three meteorological indices weighted by their predictive accuracy. This gives you transparent, passenger-focused turbulence probability instead of vague categories.
