American Airlines LAX T4.5
Los Angeles, California

American Airlines Terminal 4.5 (AA T4.5) Development Program at Los Angeles International Airport (LAX) will fully modernize and update LAX’s two busiest domestic terminals. When completed, the new facility will create a world-class customer experience with efficient check-in and security processing areas, more inviting gate areas with increased seating and modern amenities, and greater flexibility for airline operations to incorporate new technologies.

The unified departure hall will combine the entranceway of Terminals 4 and 5. Together with the secure-side bridge connecting Terminal 4 and the Tom Bradley International Terminal (TBIT), movement between terminals for connecting passengers will become significantly easier and more convenient.

The skills and craftsmanship of Southwest Steel are showcased throughout this project.
