São Paulo at $441 RT

How to make the best out of these fares to São Paulo? Sure, you could jet off to any far-flung Brazilian town directly from Guarulhos Airport. After all, it's got the vastest network of flights to cities across the country.

Orrrrr, you could just relax and spend a week on the costa verde, a stunning region between São Paulo and Rio that Brazilians have been gatekeeping — and for good reason!

I've got a soft spot for Ilha Grande. With over 73 square miles of Atlantic rainforest, gorgeous beaches, and hiking trails, it's the ultimate island paradise just a night bus away :-)
