El Salvador International Airport.
For Salvadorans eager to explore Central America, three nearby countries open their doors without requiring a passport. A simple National Identity Document, or DUI, is enough to board a plane and cross the borders.
Since 2006, El Salvador, Guatemala, Honduras, and Nicaragua have been united under the Central American Free Mobility Agreement (CA-4), a regional pact that simplifies travel within these nations. The accord allows citizens to move freely, provided they possess a valid national ID.
This unique arrangement applies to both land and air travel. Salvadorans can fly to Guatemala, Honduras, or Nicaragua by simply presenting their DUI—no passport, visa, or additional paperwork is required. The process, however, follows the same steps as any international trip at the airport.
Once round-trip tickets are purchased, travelers must complete online check-in 24 hours before departure. During that process, the DUI number is entered in the field commonly used for a passport number, ensuring the system registers the traveler correctly.
Authorities from the General Directorate of Migration and Foreigners (DGME) recommend arriving at El Salvador International Airport at least three hours before the scheduled flight. This helps avoid last-minute delays or missing boarding calls.
At the airport, passengers should visit the airline counter and present their DUI, confirming their destination is Guatemala, Honduras, or Nicaragua. If online check-in wasn’t completed, they’ll receive a physical boarding pass at this stage.
After check-in, travelers proceed directly to the security checkpoint. Thanks to updated systems, airlines now share passenger information with immigration authorities electronically, eliminating the need for a separate immigration desk for CA-4 destinations.
Once security screening is complete, travelers head to their gate and await boarding. The process is designed to be seamless, combining convenience with thorough oversight of travel documentation.
Upon arrival in any of the three countries, immigration officers will reverify the traveler’s DUI status. Entry is recorded digitally, making the arrival process as efficient as the departure process.
However, this benefit applies exclusively to adults. The DGME clarifies that minors under 18 must still present a valid passport to travel, even within CA-4 territory.
Additionally, the DUI must be current, legible, and undamaged. An expired or unreadable ID could result in denied boarding or entry at the destination.
Nearly two decades after its creation, the Central American Free Mobility Agreement continues to strengthen regional ties, offering Salvadorans the rare privilege of international air travel without a passport—just a small card that grants access to three nearby nations.
