AI-powered flight briefing
11,500 data points analyzed · HIGH confidence
Your Flight

We analysed more than 11,500 data points along your route from London Heathrow Airport, London to Detroit Metropolitan Wayne County Airport, Detroit.

Your Journey Beta

28 minutes, 1 hour 45 minutes, and 2 hours 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 and over the Appalachian Mountains – 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.
