12,500 data points analyzed · HIGH confidence
Your Flight

We analysed more than 12,500 data points along your route from Chicago O'Hare International Airport, Chicago to London Heathrow Airport, London.

Your Journey Beta

15 minutes, 31 minutes, and 1 hour 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 crossing the North Atlantic 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 a bit bumpy initially, with calm conditions around the airport.
