10,000 data points analyzed · HIGH confidence
Your Flight

We analysed more than 10,000 data points along your route from Logan International, Boston to London Heathrow Airport, London.

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.
