We know turbulence can feel scary - especially on long flights. This report is built for you: what bumps feel like, when they happen, and why they don't put the aircraft in danger. Many passengers feel exactly the same way.

Your Journey Beta

4 hours, 4 hours, and 12 hours 50 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 crossing the North Pacific Ocean and over the Appalachian Mountains – these areas can sometimes cause light turbulence.
