16,000 data points analyzed · HIGH confidence
Your Flight

We analysed more than 16,000 data points along your route from Incheon International Airport, Seoul to Vancouver International Airport, Vancouver.

Your Journey Beta

A brief bumpy patch may occur during cruise. It's nothing to worry about - just keep your seatbelt fastened.

Your route takes you crossing the North Pacific Ocean – conditions there can sometimes cause light 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 39 knots. These winds are favorable and may get you there up to 39 minutes early.

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.
