Publicación en San Juan, San Juan, Puerto Rico

From San Juan airport to the San Juan port you can take an uber. Easiest way to get from San Juan to Aguadilla is renting a car. If not you can take the Blue Line but it gets out from Río Piedras and I think you have to make a reservation. You can find their phone number here: http://amerpages.com/spa/puerto_rico/items/view/39701/blue-line-rio-piedras-aguadilla

Theres is also Línea Sultana that goes from San Juan to Mayaguez and I think they make a stop in Aguadilla. They make diferent trips every day. You also have to reserve.
Their phone is 1-787-832-2502

Hope this helps! Have a fun trip and let me inow if you need any other advice or anything!

-Maria del Mar, the airport is a "touristic area", so Uber is not available.
-PINAYGIRL, you can take a taxi to get outside the airport and then request an Uber, Uber can take you to the port, but it cannot pick customers in some touristic areas.

You can get more information here about Blue Line trips/route. http://caribya.com/puerto.rico/buses/
