LAX Southwest Airlines Terminal 1.5 Development Program

About the Project

The Southwest Airlines Terminal 1.5 Development Program at LAX is a four-story terminal connection between Terminals 1 and 2. The connector provides additional space for ticket counters, baggage carousels, a bus gate, an additional screening checkpoint and it improves the guest experience. The multi-tenant terminal building features an outbound baggage system and an inbound baggage system, a loading dock with receiving area, vertical circulation and rooms to support building services such as mechanical, electrical, plumbing and information technology. The project also includes a vertical circulation core that provides connectivity between the terminal and the future automated people mover. The Terminal 1.5 connector was designed and built to LEED Silver certification and CalGreen Tier 1 standards.
