Boston to Medellín

United's nonstop from Providence to Medellin is running $413 round trip, well under the roughly $645 this route usually commands. Medellin's spring-like climate year round, walkable Poblado neighborhood, and growing food and coffee scene make it one of South America's most approachable cities to explore. A full-service nonstop at this price out of PVD is not something that shows up often.
