Terminal 3 opened in 1961 and was Trans World Airlines' terminal. The terminal was expanded in 1970 to accommodate widebody operations and between 1980 and 1987, which included a new passenger connector building and baggage system connected to the original satellite.^[8] It formerly housed some American Airlines flights after that airline acquired Reno Air and TWA in 1999 and 2001, respectively. Eventually, all American flights were moved to Terminal 4. As of July 2015, Allegiant Air, Frontier Airlines, JetBlue Airways, Spirit Airlines, and Virgin America use Terminal 3.

Terminal 4 was built in 1961, was expanded in 1983 by adding a connector from the ticketing areas to the original satellite,^[8] and was renovated in 2002 at a cost of $400 million in order to improve the appearance and functionality of the facility. The renovation was designed by Rivers & Christian.^[9] An international arrivals facility was also added as part of the renovations but this has been closed due to staffing shortages. Currently American Airlines International flights arrive Terminal 4 and TBIT but passengers disembark via stairs onto buses that travel directly to Tom Bradley International Terminal arrivals.^[10] Some international departures operate at TBIT.

Western Airlines occupied this terminal at its opening in 1962, and continued to do so until Western was merged with Delta on April 1, 1987. Terminal 5 was redesigned by Gensler,^[11] expanded to include a connector building between the original satellite and the ticketing facilities and remodeled from 1986 through early 1988. It was unofficially named 'Delta's Oasis at LAX' with the slogan 'Take Five at LAX' when construction was completed in the summer of 1988. Northwest Airlines moved all operations to Terminal 5 and Terminal 6 alongside Delta on June 30, 2009, as part of its merger with the airline.

Terminal 6

Terminal 6 has 14 gates: Gates 60–63, 64A–64B, 65A-65B, 66, 67, 68A–68B, and 69A–69B. Parts of this terminal have changed little from its opening in 1961; in 1970, new gates were expanded from the main building, as is obvious from the rotunda at the end. Four of these gates have two jetways, which can accommodate large aircraft. An expansion of the terminal, including a connector of the original satellite to the ticketing areas, was completed in 1987.^[13]
Terminal 6 is currently used by Alaska Airlines, Copa Airlines, Delta Air Lines and Great Lakes Airlines.
Continental Airlines originally built the Connector Building (which links the Ticketing and rotunda buildings). Prior to October 2014, United Airlines used the connector gates, supplementing its base at Terminal 7. Delta also leases some space from the Airport in Terminal 6, in addition to its base at Terminal 5. Most of the rotunda gates can feed arriving passengers into a sterile corridor that shunts them to Terminal 7's customs and immigration facility.
In April 2011, Alaska Airlines agreed to a deal with Los Angeles World Airports to renovate Terminal 6 and build an Alaska Airlines Board Room Lounge. The airline moved its flights to Terminal 6 on March 20, 2012, and Spirit Airlines was relocated to Terminal 3.^[14]
Former tenants of the terminal include Continental Airlines until its merger with United Airlines in 2011 and Eastern Air Lines, which went bankrupt in 1991. The terminal also originally housed Pacific Southwest Airlines.
After the relocation of Delta Air Lines to Terminals 2 and 3 in 2017, Terminal 6 will host Aer Lingus, Air Canada, Alaska Airlines, Boutique Air, Great Lakes Airlines, Mokulele Airlines, Virgin America, and XL Airways France, as well as ticketing/check-in of passengers for Sun Country Airlines.

Added were new gate podiums, increased size of gate areas, relocated concessions, expanded restrooms, new flooring, and new signage.^[15] Also, the roof of the terminal was raised, and new, brighter light fixtures were added in order to provide more overall lighting.^[16] As of 2012, Terminal 7 is undergoing another facelift, with significant changes to concessions.
