Your Journey Beta

1 hour 10 minutes, 1 hour 30 minutes, and 1 hour 45 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 Sierra Nevada, crossing the North Pacific Ocean, crossing the South Pacific Ocean, and over the Great Dividing Range – these areas can sometimes cause turbulence.

Smooth Flight

We're expecting smooth conditions throughout your flight. You can sit back and relax.

Takeoff
