For those TRULY interested in what type of air travel is occurring within RD right now, try one of the flight tracker websites. When you determine a carrier and flight #, investigate further with that particular airline as to their schedules.
For example, right now in RD airspace, the only "international flight" happens to be a Jet Blue flight from San Juan (SJU) en route to Santo Domingo (SDQ).
There are also 2 private aircrafts, and 2 helicopters in motion. A rather fascinating tool to utilize.
