Transportation Secretary Sean Duffy joins 'America's Newsroom' to weigh in after extreme turbulence forced a Delta Airlines flight to divert to Minneapolis and as NTSB hearings begin on the deadly Washington, DC crash from January.

Not all flight routes are created equal when it comes to turbulence.

A recent report from turbulence tracking site Turbli ranked the most turbulence-prone flight routes in the U.S. and around the world in 2025.

The organization analyzed nearly 10,000 flight routes connecting more than 550 of the world’s largest airports — using recorded flight tracks and turbulence forecast data, the analysis said.

Turbulence was measured using eddy dissipation rate (EDR), a standard aviation metric that captures how rough the air is during a flight.

Routes were ranked based on their average turbulence levels, with EDR values categorized as light, moderate, moderate-to-severe, severe and extreme.

The higher the average EDR score along a route — the more turbulence passengers are likely to experience, according to the analysis.
