I like to travel. But to avoid stress, you need to plan everything in advance. Planning a big trip always starts with the same problem: finding affordable flights. For my South America plans, I tried Aviasales https://aviasales.us.com/vs-competitors and liked how easy it was to compare options. It doesn’t cost anything to check prices, and you’re not limited to one booking platform. Sometimes the cheapest option is an airline, sometimes it’s a travel agency — having everything visible makes the choice much easier.
