Those who are frequent flyers must have experienced turbulence at least once. Although facing turbulence is common in flight, at times it can turn more dangerous than thought. Here are seven locations where your flight is likely to face some severe turbulence: 

Santiago, Chile to Santa Cruz, Bolivia

The route passes the Andes Mountains which can cause significant turbulence because of varying air currents and the mountainous terrain. 

Almaty, Kazakhstan to Bishkek, Kyrgyzstan 

The route covers the Tian Shan mountain range which can lead to turbulence, especially during shifts in weather patterns. 

Lanzhou to Chengdu, China 

The Tibetan Plateau and Sichuan Basin are covered in this flight route. This area has high elevation and rugged terrain which can lead to turbulence. 

Milan, Italy to Geneva, Switzerland  

This route passes the Alps which is a huge mountain range in Europe. The weather systems in the region as well as the high terrains can lead to a turbulent flight experience. 

Osaka, Japan to Sendai, Japan 

The mountainous regions of Honshu and the weather patterns over the Sea of Japan influence this route. 

Xianyang to Chongqing, China 

This route covers a varied landscape which includes the Qinling Mountains and the Sichuan Basin. The weather patterns of central China and the geographical variations can create turbulence on flight. 

Lanzhou to Xianyang, China 

This route crosses the Loess Plateau. The region's unique topography and air currents can lead to turbulence in the flight.
