8,000 data points analyzed · HIGH confidence
Your Flight

We analysed more than 8,000 data points along your route from Toronto Lester B. Pearson International Airport, Toronto to Keflavik International Airport, Reykjavík.

Your Journey Beta

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 smooth with possible light bumps, with calm conditions around the airport.
