I don't think Aeromar flies to JFK. Just Miami. They just inagurated, this week, the Miami-Puerto Plata (formerly operated only by American) and Miami-Punta Cana (formerly operated only by LanChile) routes. None the less, I'll take AA to the Domincan Republic over the other carriers anyday. American offers greater frequency - 5 dailies from Miami - with newer, larger aircraft (A300s and 757s). Aeromar only flies Miami-Santo Domingo non-stop four times a week, and they can't even use thier own planes, they use Allegro 727s.
