AI-powered flight briefing
11,000 data points analyzed · HIGH confidence
Your Flight

We analysed more than 11,000 data points along your route from Toronto Lester B. Pearson International Airport, Toronto to London Heathrow Airport, London.

Your Journey Beta

26 minutes and 1 hour 25 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 and crossing the North Atlantic Ocean – these areas 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 a bit bumpy initially, 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 28 minutes early.

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.
