The immigration travel route

What route was followed more frequently by ships transporting immigrants?

To think that our forbears departed from Europe and landed directly in an American port is an erroneous concept.
Shipping companies traveled through different routes, including several other ports, where immigrants stayed temporarily and they could start again another travel with better possibilities of new jobs. The route most frequently used was one with a first stop in the port of New York.
Later, it followed a route towards the South of the continent, arriving in different South American ports, like Brazil, Montevideo (Uruguay) and Buenos Aires.

Apparently, this one was the more frequently used at that time.
