$333 rt SFO to San Juan

United Airlines

7.6 Deal Rating

Five centuries ago, San Juan was an uninviting, impenetrable fortress city. Today, Puerto Rico's festive capital is one of the most popular Caribbean destinations as it offers passport-free travel from the United States. Tourists can expect one of the most culturally-rich places in the world with the added allures of a tropical Caribbean island.

Heads Up

This is a good deal offering one-stop service with short layovers at around a 25% discount. Note that Delta and American also have similar fares (and availability) if you prefer those airlines.
