La Isabela International Airport is the closest airport to the city centre making transfers to Santo Domingo faster than at SDQ. The airport better because it handles less crowds with less queues at immigration and fewer flight delays than SDQ which sees more. Las Americas International Airport is bigger with a single terminal, 2levels and 2 concourses (A & B), than La Isabela's single terminal with 2 levels. This means moving around the airport will be a bit tiring. Business travellers will most likely prefer to use La Isabela International to Las Americas International due to the shorter transfer times, fewer flight delays, and cheap flight fares.
