Your Flight

We analysed more than 24,000 data points along your route from Toronto Lester B. Pearson International Airport, Toronto to Hong Kong International Airport, Hong Kong.

Your Journey Beta

3 hours, 3 hours 10 minutes, and 3 hours 15 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 over the Appalachian Mountains, crossing the Hudson Bay, crossing the Arctic Ocean, and crossing the South China 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 smooth with possible light bumps, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 30 knots. These winds are favorable and may get you there a few minutes early.

Landing

Landing should feel smooth 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.
