American Airlines is on a journey to redevelop its hub at Los Angeles International Airport (LAX) and improve the customer experience at the two busiest domestic terminals.

The airline, which will celebrate 75 years of service to Los Angeles later this year, recently celebrated a significant milestone in its construction journey at LAX, in which team members signed their names onto a piece of history that will prominently live atop of the Terminal 4 and 5 CORE.

The CORE is the primary, centralised structure that connects the terminal areas with the screening checkpoint, ticketing and baggage claim areas, as well as the automated people mover train system, curbside and parking areas.

In a topping out ceremony, team members and leaders from American were joined by executives from Los Angeles World Airports (LAWA) to celebrate the final steel beam being raised into place and secured by its construction partners.

“We are creating the airport of the future at LAX, setting new standards for design, functionality, ease of use and the overall passenger experience,” said Justin Erbacci, chief executive, Los Angeles World Airports.

“The topping off of Terminal 4.5 is another step forward in our overall modernization program, and we are proud to partner with American Airlines to fulfil our vision of delivering a world-class airport.”
