About

The modernization of Terminal 1 includes two separate projects, detailed below.

Terminal 1 Extension (Completed 2021)

The $477.5 million extension of Terminal 1 opened to the public in May 2021. This facility includes the first of seven terminal vertical cores, which will connect the APM system to the terminal via an elevated pedestrian bridge, to open at Los Angeles International Airport's (LAX). The Terminal 1 core will connect travelers to the Center Central Terminal Area (CTA) station in the future and includes elevators and escalators for passenger movement.

The extension also connects Terminal 1 to Terminal 2 post-security screening via a bridge that allows passengers to move between the two buildings without having to be re-screened, providing greater flexibility for passengers.

It also includes two new baggage carousels on the Lower/Arrivals level, additional ticket counters on the Upper/Departures level and a six-lane Transportation Security Administration (TSA) checkpoint with Automated Screening Lane (ASL) technology on the Concourse level. The new portion of the ticketing lobby includes self-service check-in kiosks with biometric and touch-free capabilities.

The extension to Terminal 1 was certified Leadership in Energy and Environmental Design (LEED) Silver certified by the U.S. Green Building Council in 2021.

Among the green building features of the facility:

• A new recycled water system that is being installed around the airport campus that will work in concert with low-flow faucets and flush valves, resulting in substantial reductions in the amount of potable water used by the building.
• A new stormwater collection and management system collects all rainwater runoff, which is filtered and reclaimed at an off-site treatment facility. This system ensures that rainwater will be treated and reused as opposed to directly draining into the Pacific Ocean.
• An advanced lighting control system that is programed to automatically increase or decrease the amount of artificial light within the building depending on both the time of day and number of occupants within the building.
• Advanced, energy efficient air handling units that maintain occupant comfort within the building by accurately monitoring and regulating temperature, humidity and air quality. The units use fan wall arrays and can function in full 100-percent outside air mode to take advantage of LAX’s cool coastal climate. In addition to Merv14 filtration, the new air handlers use both bi-polar ionization and ultra-violet germicidal irradiation to provide healthy indoor air quality possible.

Terminal 1 Modernization (Completed 2018)

The $507 million modernization of Terminal 1 was completed in 2018, with improvements to the interior space, the outdoor aircraft parking ramp area and the traffic flow around the CTA. The terminal was 30 years old when work began, and building systems were nearing the end of their useful life. This renovation replaced them with more efficient and environmentally friendly equipment.

Interior upgrades included:

• New, state-of-the-art, consolidated TSA screening checkpoint in the east end of the building, eliminating a bottleneck in the middle of the building
• New ticketing lobby
• Fully automated checked baggage inspection and sorting system
• Integrated passenger waiting room/concessions program
• Refurbished arrival/baggage claim area
• Replacement of passenger boarding bridges
• Renovations to office spaces supporting airline operations
• Relocation of the main entrances towards the west end of the building to ease traffic congestion

Improvements to the ramp area (adjacent to the airfield) included:

• Accommodation of 13 Boeing 737-sized aircraft
• Pavement replacement
• Modernized hydrant fuel system
• Electric vehicle chargers to support an electric ground service equipment program
