AI-powered flight briefing
16,000 data points analyzed · HIGH confidence
Your Flight

We analysed more than 16,000 data points along your route from Harry Reid International Airport, Las Vegas to London Heathrow Airport, London.

Your Journey Beta

9 hours 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 Rocky 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.

Winds Aloft
