Check-In Times: Airlines typically open check-in counters 2-3 hours before flights
When planning your trip through San Juan Airport (SJU), understanding the check-in times is crucial for a smooth travel experience. Airlines operating out of San Juan Airport typically open their check-in counters 2 to 3 hours before scheduled flight departures. This standard practice ensures passengers have ample time to complete the check-in process, drop off their luggage, and proceed through security without rushing. It’s important to note that while the airport itself may open earlier, airline-specific services like check-in counters adhere to this timeline.
To determine the exact opening time of the check-in counters for your flight, you should verify the departure time of your flight and count backward 2 to 3 hours.

While the 2-3 hour rule is standard, some airlines may have specific policies or recommendations. For instance, international flights often require passengers to check in earlier, sometimes up to 3 hours before departure, due to additional security and customs procedures.
