Terminal 1.5 Development Program at Los Angeles International Airport (LAX)

The Terminal 1.5 Program is the development of a new, 225,000-square-foot, four-story terminal facility at LAX, located between Terminals 1 and 2, to support various airlines over the next 20+ years.

Initially, the terminal will be used by Southwest Airlines, but following the completion of the new Midfield Satellite Concourse, several other airlines will shift their ticketing operations into Terminal 1.5.  Those passengers will then utilize the ticketing lobby, security checkpoint, and bus gate at terminal 1.5 bus to depart LAX from the new Midfield Satellite Concourse.

The new facility will ease congestion and provide connectivity between the two terminals – both within the ticketing and check in portion as well as post-security screening. The new terminal’s post-security airside pedestrian connection means passengers connecting between the terminals will no longer have to leave the secure area of the concourse, exit the building, and go through security again to make a connection.

The multi-tenant building will include baggage claim, ticketing, security checkpoint, airside connector, retail concessions, and leasable office space. Also included is a bus gate, outbound baggage system (including CBIS), and 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 with also be included. The Project also includes a vertical circulation core which provides connectivity between the terminal and the future automated people mover. 

Features include:

1. Post-security airside pedestrian connection between Terminals 1 and 2

2. Concessions

3. Airline offices and pilot/flight attendant base
