Santiago has nonstop service from ATL, MIA, and JFK on LATAM, American, and Delta, with flight times around 9 to 10 hours.
Santiago is in the Southern Hemisphere: Chilean summer (December–February) is peak for city and wine-country tourism, warm and dry. Chilean winter (June–August) is ski season in the nearby Andes — a different kind of peak demand for winter-sports travelers — while being the off-season for general city tourism. Shoulder season (March–May, September–November) offers good value.
There's no dedicated low-cost carrier on this nonstop route — LATAM, American, and Delta compete on price, so booking within the optimal window matters more than airline choice, and depends on whether you're chasing summer city travel or winter ski season.
