For international departures from Punta Cana International Airport (PUJ) in the Dominican Republic, it is highly recommended to arrive at least 3 hours before your scheduled flight. While the airport features beautiful open-air terminals, it is one of the busiest in the Caribbean and can experience significant bottlenecks at check-in counters and passport control, especially during peak hours (11:00 AM to 4:00 PM). If you are traveling during the high season (December through April) or on a weekend, arriving 3.5 hours early is safer. The airport also requires an "e-ticket" (digital entry/exit form), which should be completed before you reach the terminal to avoid delays at the security entrance. Having extra time allows you to navigate the potentially long immigration queues without stress.
