FL180 on descent to an airport, could it be due to mountain wave?

World record glider flights happen in Chile due to what us glider folks would call excellent conditions for mountain wave.

Could be but doubt it. METAR at SCEL would't indicate anything relating to mountain waves and winds are very light and VRB too.Also FL180 is still fairly high but area weather is not included in the report so who knows.

I've never flown in a glider but sounds fun! Definitly need to try it one day.

If this was "descending through FL 180", it means somewhere over the Argentinean-Chilean border, in the middle of the Andes mountains. It is a well known area for turbulence, hence every time I have flown that leg the crew warned all passengers to get back to their seats and put the seat-belts on. Since AF is flying that same route every day now, I would like to think that the crew was well aware of that and/or they have been made aware of this fact, but maybe it was a crew unfamiliar with this route. Beware that the crossing of the Andes during descent brings you right along the Aconcagua mountain (22,831 ft), so you get pretty close to the surrounding mountains.

This is what it looks like:

Tell me about it. The first time I felt real turbulence was precisely crossing the Andes, being a 9 y.o. boy...30 years later I still remember the sounds of the poor 732 and the screams of the people around me....surprisingly I stayed very calm and I can even say that I enjoyed the ride a little...

Would the approach into Santiago over the Andes be about the same as the approach into Denver over the Rockies in terms of turbulence? I have never had a smooth flight in/out of Denver. It always seems to be turbulent and the crew almost always seems to get the cabin ready for landing earlier than normal because of the expected bumps.
every day is a good day to fly

I had never been in Denver, but if the frequency of ( moderate to severe ) turbulence is high, then my answer is no. I have a lot, a looot of landings into SCL, and I only have turbulence episodes a fraction of the times, and usually moderate or less, probably only a couple of times of real severe turbulence.

( Just my personal experience )

While the turbulence around Denver isn't severe, it's moderate to heavy chop all the way down on most of my many flights into the airport. It's very annoying, and probably bothersome to less seasoned flyers.

It is always upsetting to here when FA's get hurt on the job due to turbulence.....its more upsetting to try to figure out why pax don't follow the seatbelt signs and stay seated when there is turbulence........

Just alittle more about turbulence over the Andes, especially my experience with aB744:

Yes, except that you don't fly over the Andes from EZE to LHR
