Turbli breaks down the most turbulent routes in the world. This includes a list of the routes in North America that are estimated to have the most turbulence.
The recent incident involving a Singapore Airlines flight that had to make an emergency landing in Bangkok on Tuesday following "severe turbulence" has sparked heightened awareness around the dangers of turbulence and areas where passengers are likely to experience it.
The Boeing 777-300ER jet was heading from London to Singapore with 211 passengers and 18 crew onboard when it "encountered severe turbulence en-route" over Burma. One person died and 30 were injured.
Weather.gov describes turbulence as "one of the most unpredictable of all the weather phenomena that are of significance to pilots."

According to the Federal Aviation Administration (FAA), turbulence is created by atmospheric pressure, jet streams, air around mountains, cold or warm weather fronts or thunderstorms.
It could be "as insignificant as a few annoying bumps" but it can also "momentarily throw an airplane out of control or to cause structural damage," according to Weather.gov.
During the Singapore Airlines incident, flight tracking data from the website FlightAware shows the aircraft quickly lost several thousand feet of altitude after traveling at 37,000 feet.
Turbli analyzed 150,000 routes and ranked those with active airline routes as of December 2023.
The most turbulent flight was the route from Santiago in Chile to Santa Cruz in Bolivia, according to the data. Meanwhile, the second most turbulent route was determined to be between Almaty, Kazakhstan, and Bishkek, Kyrgyzstan, followed by Lanzhou, the capital city of northwest China's Gansu province, and Chengdu, the capital of southwestern China's Sichuan province.
