Home Transforming LAX Projects Underway T4 T5

ongoing

Terminals 4 and 5, home to American Airlines, JetBlue and Spirit Airlines, is undergoing a $1.6 billion modernization slated to complete in 2027 that will create a centralized location for ticketing, screening and baggage claim with enhanced amenities for guests, as well as provide direct connection to the Automated People Mover (APM) train system. The modernization project includes a Terminal Vertical Core, which provides for vertical circulation of passengers with escalators and elevators, as well as connection to the APM’s West Central Terminal Area (CTA) station via an elevated pedestrian walkway over World Way. The Terminal Vertical Core also will include new passenger check-in and baggage claim facilities, a consolidated security screening checkpoint, a new headhouse area for passenger processing and a new post-security connection between Terminals 4 and 5. The Terminal Vertical Core also provides office and support spaces for airlines, the Transportation Security Administration (TSA) and other law enforcement agencies. A new south concourse will be constructed inside Terminal 4, featuring additional space for hold rooms, concessions, restrooms and a bus gate that will serve both domestic and international traffic. Two existing aircraft gates will also be rebuilt to support U.S. Customs and Border Protection Federal Inspection Station capability. Improvements will be made to the north concourse that will increase the efficiency of passenger movements. Additional work includes improvements to Terminal 4 power systems, including transformers and backup power, replacement of the terminal's aircraft apron and a reconfiguration of its hydrant fueling system and underground utilities.
