Hi. I plan to go from Mendoza to Valparaiso in early October. A day's delay would really mess up my planned schedule. My initial plan was to take the bus but I've read some recent posts and it looks like I risk a lengthy delay due to weather as well as sheer terror (I have vertigo). I've also looked at Sky Airlines who are the cheapest by a mile but their reviews aren't so good. Are they considered safe? reliable? Would you take them or pay a LOT more for LATAM?
