Southwest Airlines Terminal 1.5 (SWA T1.5) Development Program at Los Angeles International Airport (LAX) is a $350 million, four-story terminal connection between Terminals 1 and 2. The 239,538 SF connector provides additional space for ticket counters, baggage carousels, bus gate, additional screening checkpoint, and an improved guest experience. The multi-tenant terminal building features an outbound baggage system (including CBIS) and an inbound baggage system, loading dock with receiving area, vertical circulation, and rooms to support building services such as mechanical, electrical, plumbing, and information technology. Terminal 1.5 also includes a vertical circulation core that provides connectivity between the terminal and the future automated people mover.

Terminal 1.5 is a LEED Silver project. The skill and craftsmanship of Southwest Steel are prominently displayed throughout this project.
