Terminal MAIN hosts 3 airlines across 4 gates.
The Main Terminal at Rafael Hernández Airport is a small, straightforward facility that consolidates all check-in, security, boarding, and baggage claim functions under one roof. Passengers typically check in with JetBlue, Frontier, or United at counters in the departures hall before proceeding through security to a modest gate area that can accommodate several narrowbody aircraft serving routes to Florida and the U.S. East Coast.[1][3][6] The building is designed for quick passenger throughput rather than extensive shopping or dining, which helps keep walking distances short and makes navigation easy even for first-time visitors.
Amenities in the terminal are basic but functional, with essential services such as restrooms, limited food and beverage options, and rental car counters, though offerings can vary by time of day. Seating areas are relatively compact, so they may feel busy around peak departures, but the overall experience is generally relaxed compared to larger Caribbean hubs. Because there is only one terminal, all arrivals exit into a common landside area where ground transportation and parking are located just a short walk away.
