Reina Beatrix splits into four buildings, not two terminals: two separate check-in halls flank the Arrivals building, and a shared core behind them holds the gates. The hall to the right is U.S. Departures — where Aruba runs its own U.S. Customs and Border Protection Pre-Clearance — and the hall to the left is Non-U.S. Departures, for every other destination; both feed into the shared terminal core, which the airport describes as three floors of shops, dining and relaxing facilities. That left/right split by destination, not by airline or terminal letter, is the detail the check-in guide spells out and the map below labels accordingly.
The shaded buildings are the terminals as they operate today, with names verified by us — the base map’s own labels can lag behind reality. Blue P squares mark the official car parks that publish a name; the dark square is the station.
