JBQ
La Isabela International Airport (Dr. Joaquin Balaguer)
Quick answer
Santo Domingo's northern airport, the base for domestic and regional Caribbean flights. From the airport to central Santo Domingo: taxi about $20-25, 30 minutes depending on traffic.
The airport trick
No intercity bus departs directly from the air terminals. The right pattern is: short ride from the airport to the bus stop, then the intercity guagua. Guagualine solves both pieces in a single booking.
