Is the flight from Lima to Santiago bumpy?
The Lima–Santiago flight is usually smooth, with some bumpy stretches at certain times of year. Here is where the plane can move, when it happens most, and how to check today’s forecast for your flight.
Where the plane can move
The Andes: mountain waves
The Andes are among the highest mountain ranges in the world. With strong winds, waves form downwind of the peaks and can move the plane, mostly when climbing or descending near them. Crews who fly here daily know it well and adjust route and altitude.
Southern South America: the southern jet stream
The southern hemisphere has a jet stream too, stronger in its winter (June to August). It can bring patches of clear-air turbulence, usually light.
At the airports
Santiago sits at the foot of the Andes: climbing or descending across the range is when movement is most likely.

Tips for this flight
- Seats over the wings usually feel the least movement; the back of the plane feels the most.
- Keep your seatbelt fastened whenever you are seated, even with the sign off. The FAA warns that turbulence can throw unbelted passengers from their seats without warning.
- If the captain switches on the seatbelt sign, it is a precaution: turbulence is a normal part of flying.
