There are zero Arajet flights from Santiago from April 2025. There are 6 destinations on their website when you select leaving from Santiago and those are Bogota, Colombia - Buenos Aires, Argentina - Lima, Peru - Medellin, Colombia - Santiago, Chile and Sau Paulo, Brazil. But if you select the dates for anytime this year, no flights are available with the exception of Medellin up until the 27th of March 2025. By the looks of it, Arajet are pulling out of Santiago despite adding new flights from Santo Domingo and Punta Cana. I hope that changes in the near future as I have taken the Medellin flight twice in the last year.
