In 2019, LAX handled 88,068,013 passengers, making it the world's third busiest and the United States' second busiest airport following Hartsfield-Jackson Atlanta International Airport. As the largest and busiest international airport on the U.S. West Coast, LAX is a major international gateway to the United States, and also serves a connection point for passengers traveling internationally. The airport holds the record for the world's busiest origin and destination airport, since relative to other airports, many more travelers begin or end their trips in Los Angeles than use it as a connection. It is also the only airport to rank among the top five U.S. airports for both passenger and cargo traffic.
Los Angeles Municipal Airport on Army Day, c. 1931
Mines Field opened as the airport of Los Angeles in 1930 and the city purchased it to be a municipal airfield in 1937. The name became Los Angeles Airport in 1941 and Los Angeles International Airport in 1949. In the 1930s the main airline airports were Burbank Airport (then known as Union Air Terminal, and later Lockheed) in Burbank and the Grand Central Airport in Glendale. (In 1940 the airlines were all at Burbank except for Mexicana's three departures a week from Glendale; in late 1946 most airline flights moved to LAX, but Burbank always retained a few.)
Mines Field did not extend west of Sepulveda Boulevard; Sepulveda was rerouted circa 1950 to loop around the west ends of the extended east-west runways (now runways 25L and 25R), which by November 1950 were 6,000 feet (1,800 m) long. A tunnel was completed in 1953 allowing Sepulveda Boulevard to revert to straight and pass beneath the two runways; it was the first tunnel of its kind. For the next few years the two runways were 8,500 feet (2,600 m) long.
The "X" in LAX
Before the 1930s, US airports used a two-letter abbreviation and at that time, "LA" served as the designation for Los Angeles Airport. With the rapid growth in the aviation industry, in 1947, the identifiers expanded to three letters and "LA" received an extra letter to become "LAX." The letter "X" does not otherwise have any specific meaning in this identifier. "LAX" is also used for the Port of Los Angeles in San Pedro and by Amtrak for Union Station in downtown Los Angeles.
LAX Theme Building, July 1962
The distinctive white GoogieTheme Building, designed by Pereira & Luckman architect Paul Williams and built in 1961 by Robert E. McKee Construction Co., resembles a flying saucer that has landed on its four legs. A restaurant with a sweeping view of the airport is suspended beneath two arches that form the legs. The Los Angeles City Council designated the building a Los Angeles Historic-Cultural Monument in 1992. A $4 million renovation, with retro-futuristic interior and electric lighting designed by Walt Disney Imagineering, was completed before the Encounter Restaurant opened there in 1997 but is no longer in business. Visitors are able to take the elevator up to the observation deck of the "Theme Building", which had previously been closed after the September 11, 2001 attacks for security reasons. A memorial to the victims of the 9/11 attacks is located on the grounds, as three of the four hijacked planes were originally destined for LAX. The Bob Hope USO expanded and relocated to the first floor of the Theme Building in 2018.

Since 1972, Los Angeles World Airports has adopted the "Preferential Runway Use Policy" to minimize noise. During daylight hours (0630 to 0000), the normal air traffic pattern is the "Westerly Operations" plan, named for the prevailing west winds. Under "Westerly Operations", departing aircraft take off to the west, and arriving aircraft approach from the east. To reduce noise from arriving aircraft during night hours (0000 to 0630), the air traffic pattern becomes "Over-Ocean Operations". Under "Over-Ocean", departing aircraft continue to take off to the west, but arriving aircraft approach from the west unless otherwise required to approach from the east due to reduced visibility or easterly winds. As the name implies, "Easterly Operations" is used when prevailing winds have shifted to originate from the east, typically during inclement weather and Santa Ana conditions. Under "Easterly Operations", departing aircraft take off to the east, and arriving aircraft approach from the west.
The "inboard" runways (06R/24L and 07L/25R, closest to the central terminal area) are preferred for departures, and the "outboard" runways are preferred for arrivals. During noise-sensitive hours (2200 to 0700) and "Over-Ocean Operations", the "inboard" runways are used preferentially, with arrivals shifting primarily to 06R/24L and departures from 07L/25R. Historically, over 90% of flights have used the "inboard" departures and "outboard" arrivals scheme.
During westbound operations during the daytime, airplanes parked on the north complex tend to use Runway 6R/24L for almost all departures, and airplanes parked on the south complex use Runway 7L/25R for all departures requiring the left turn, and Runway 24L if they are making an immediate right turn. For arrivals, flights coming from the north tend to use Runway 6L/24R, and flights coming from the south tend to use Runway 7R/25L. For flights having a long final westbound, either arrival runway might be used, depending on flight route and/or point of origin.
The South Airfield Complex tends to see more operations than the North, due to a larger number of passenger gates and air cargo operations. Runways in the North Airfield Complex are separated by 700 feet (210 m). Plans have been advanced and approved to increase the separation by 260 feet (79 m), which would allow a central taxiway between runways, despite opposition from residents living north of LAX. The separation between the two runways in the South Airfield Complex has already increased by 55 feet (17 m) to accommodate a central taxiway.
During westbound operations during the daytime, airplanes taking off to the west with an eastbound destination will generally depart the south runways and make a left turn over the Palos Verdes Peninsula, due to terrain and airspace conflicts with the nearby Santa Monica Airport and Burbank Airport. Meanwhile, northbound flights primarily depart the north runways, climbing over the Santa Monica Bay. Westbound flights may depart either complex, as air traffic demands dictate.
LAX has nine passenger terminals with a total of 146 gates arranged in the shape of the letter U or a horseshoe that are identified by numbers except for the Tom Bradley International Terminal. The Midfield Satellite Concourse, now renamed the West Gates, an expansion for international flights reached through the Tom Bradley Terminal, opened on May 1, 2021. There are 2 million square feet (190,000 m2) of cargo facilities at LAX, as well as a heliport operated by Bravo Aviation.
LAWA currently has several plans to modernize LAX, at a cost of $14 billion. These include terminal and runway improvements, which will enhance the passenger experience, reduce overcrowding, and provide airport access to the latest class of very large passenger aircraft; this would bring LAX's total gates from 132 to 165. 
^Qantas also flies to/from New York-JFK, but only for international, connecting traffic. Due to U.S. federal law, foreign airlines may not transport revenue passengers solely between U.S. destinations.
Shuttles operate to and from the terminals, providing frequent service for connecting passengers. However, connecting passengers who use these shuttles must leave and then later reenter security. Tunnels or above-ground connectors link terminals 4, 5, 6, 7, 8, and TBIT. The above-ground connector between TBIT and Terminal 4 opened in February 2016. 
LAX City Bus Center, prior to its demolition and reconfiguration
The LAX automated people mover (APM) is an electric train system currently under construction by LAWA. The LAX APM will be 2.25 miles (3.62 km) in traveling distance and will have six stations serving the central area, terminals 1-8, and the Tom Bradley International Terminal.
Once leaving the three terminal stations, heading east, the first station is a ground transportation parking structure called the "Intermodal Transportation Facility-West" that will serve employee parking, surrounding hotel access and long term airport parking. The next station will be a second car/bus/bike transport facility called the "Intermodal Transport Facility-East" as well as LA Metro Rail's platform, the under construction ground infill transit transfer station on the K Line. At this multi-station stop, the first (floor) level will be ground transportation. The second level will be a bridge from the main hub to the light rail platform and APM platform. The third level will be the APM platform. The last stop on the APM will be a rental car hub station called the Consolidated Rent-A-Car-Center (CONRAC). All the car rental companies and rentals will be here. The APM was designed to decrease the need for shuttle bus services and reduce traffic within the terminals World Way.
The APM will have nine total trains, each operating in four car sets with capacity of containing up to 200 passengers. The APM will operate every two minutes, with a ten minute end-to-end travel time. LAWA has split the project in three phases. The project has been approved and the construction and operating bidding process was commenced. Three firms submitted bids and LAWA announced scoring for the project would be based on "technical merit, visual appeal, user experience and price". LAWA proposed a public private partnership wherein a private sector partner would responsible for the construction and operation of the people mover. Los Angeles City Council gave final approval on April 11, 2018 to "LAX Integrated Express Solutions". The three phase project is estimated to cost $5.5 billion, and have a completion date of 2023.
Arriving passengers take a shuttle or walk to the LAXit waiting area east of Terminal 1 for taxi or ride-share pickups.Taxicab services are operated by nine city-authorized taxi companies and regulated by Authorized Taxicab Supervision Inc. (ATS). ATS queues up taxis at the LAXit waiting area.
The Flight Path Learning Center is a museum located at 6661 Imperial Highway and was formerly known as the "West Imperial Terminal". This building used to house some charter flights (e.g. Condor Airlines, Martinair Holland, World Airways) and regular scheduled flights by MGM Grand Air. It sat empty for 10 years until it was re-opened as a learning center for LAX.
The center contains information on the history of aviation, several pictures of the airport, as well as aircraft scale models, flight attendant uniforms, and general airline memorabilia such as playing cards, china, magazines, signs, even a TWA gate information sign. The museum also offers school tours, community tours, and a guest speaker program.
The museum's library contains an extensive collection of rare items such as aircraft manufacturer company newsletters/magazines, technical manuals for both military and civilian aircraft, industry magazines dating back to World War II and before, historic photographs and other invaluable references on aircraft operation and manufacturing.
LAX Airport Response Coordination Center used to coordinate emergency response
During its history there have been numerous incidents, but only the most notable are summarized below:
On January 23, 1939, the sole prototype Douglas 7B twin-engine attack bomber, designed and built as a company project, suffered a loss of the vertical fin and rudder during a demonstration flight over Mines Field, flat spun into the parking lot of North American Aviation, and burned. Another source states that the test pilot, in an attempt to impress the Gallic passenger, attempted a snap roll at low altitude with one engine feathered, resulting in the fatal spin. Douglas test pilot Johnny Cable bailed out at 300 feet, his chute unfurled but did not have time to deploy, he was killed on impact, the flight engineer John Parks rode in the airframe and died, but 33-year-old French Air Force Capt. Paul Chemidlin, riding in the aft fuselage near the top turret, survived with a broken leg, severe back injuries, and a slight concussion. The presence of Chemidlin, a representative of a foreign purchasing mission, caused a furor in Congress by isolationists over neutrality and export laws. The type was developed as the Douglas DB-7.
On November 20, 1940, the prototype NA-73X Mustang, NX19998, first flown October 26, 1940, by test pilot Vance Breese, crashed this date. According to P-51 designer Edgar Schmued, the NA-73 was lost because test pilot Paul Balfour refused, before a high-speed test run, to go through the takeoff and flight test procedure with Schmued while the aircraft was on the ground, claiming "one airplane was like another". After making two high speed passes over Mines Field, he forgot to put the fuel valve on "reserve" and during the third pass ran out of fuel. An emergency landing in a freshly plowed field caused the wheels to dig in, the aircraft flipped over, the airframe was not rebuilt, the second aircraft being used for subsequent testing.
On October 26, 1944, WASP pilot Gertrude Tompkins Silver of the 601st Ferrying Squadron, 5th Ferrying Group, Love Field, Dallas, Texas, departed Los Angeles Airport, in a North American P-51D Mustang, 44-15669, at 1600 hrs PWT, headed for the East Coast. She took off into the wind, into an offshore fog bank, and was expected that night at Palm Springs. She never arrived. Due to a paperwork foul-up, a search did not get under way for several days, and while the eventual search of land and sea was massive, it failed to find a trace of Silver or her plane. She is the only missing WASP pilot. She had married Sgt. Henry Silver one month before her disappearance.
On January 13, 1969, Scandinavian Airlines System Flight 933Douglas DC-8-62, crashed into Santa Monica Bay, approximately 6 nautical miles (11 km) west of LAX at 7:21 pm, local time. The aircraft was operating as flight SK933, nearing the completion of a flight from Seattle. Of nine crewmembers, three lost their lives to drowning, while 12 of the 36 passengers also drowned.
On January 18, 1969, United Airlines Flight 266 a Boeing 727-100 bearing the registration number N7434U, crashed into Santa Monica Bay approximately 11.3 miles (18.2 km) west of LAX at 6:21 pm local time. The aircraft was destroyed, resulting in the death of all 32 passengers and six crew members aboard.
On August 6, 1974, a bomb exploded near the Pan Am ticketing area at Terminal 2; three people were killed and 35 were injured.
On March 1, 1978, two tires burst in succession on a McDonnell Douglas DC-10-10 on Continental Airlines Flight 603 during its takeoff roll at LAX and the plane, bound for Honolulu, veered off the runway. A third tire burst and the DC-10's left landing gear collapsed, causing a fuel tank to rupture. Following the aborted takeoff, spilled fuel ignited and enveloped the center portion of the aircraft in flames. During the ensuing emergency evacuation, a husband and wife died when they exited the passenger cabin onto the wing and dropped down directly into the flames. Two additional passengers died of their injuries approximately three months after the accident; 74 others aboard the plane were injured, as were 11 firemen battling the fire.
On the evening of March 10, 1979, Swift Aire Flight 235, a twin-engine Aerospatiale Nord 262A-33 turboprop en route to Santa Maria, was forced to ditch in Santa Monica Bay after experiencing engine problems upon takeoff from LAX. The pilot, co-pilot, and a female passenger drowned when they were unable to exit the aircraft after the ditching. The female flight attendant and the three remaining passengers--two men and a pregnant woman--survived and were rescued by several pleasure boats and other watercraft in the vicinity.
On August 31, 1986, Aeroméxico Flight 498, a DC-9 en route from Mexico City, Mexico to Los Angeles, began its descent into LAX when a Piper Cherokee collided with the DC-9's left horizontal stabilizer over Cerritos, causing the DC-9 to crash into a residential neighborhood. All 67 people on the two aircraft were killed, in addition to 15 people on the ground. 5 homes were destroyed and an additional 7 were damaged by the crash and resulting fire. The Piper went down in a nearby schoolyard and caused no further injuries on the ground. As a result of this incident, the FAA required all commercial aircraft to be equipped with Traffic Collision Avoidance System (TCAS).
On February 1, 1991, USAir Flight 1493 (arriving from Columbus, Ohio), a Boeing 737-300, landing on runway 24L at LAX, collided on touchdown with a SkyWest AirlinesFairchild Metroliner, Flight 5569 departing to Palmdale. The Skywest plane was given clearance to wait on the runway for takeoff. The same controller then gave the USAir plane clearance to land on the same runway, forgetting that the SkyWest plane was there. The collision killed all 12 occupants of the SkyWest plane and 23 people aboard the USAir 737.
Al-Qaeda attempted to bomb LAX on New Year's Eve 1999/2000. The bomber, Algerian Ahmed Ressam, was captured in Port Angeles, Washington, the U.S. port of entry, with a cache of explosives that could have produced a blast 40 times greater than that of a car bomb hidden in the trunk of the rented car in which he had traveled from Canada. He had planned to leave one or two suitcases filled with explosives in an LAX passenger waiting area. He was initially sentenced to 22 years in prison, but in February 2010 an appellate court ordered that his sentence be extended.
In the 2002 Los Angeles International Airport shooting of July 4, 2002, Hesham Mohamed Hadayet killed two Israelis at the ticket counter of El Al Airlines at LAX. Although the gunman was not linked to any terrorist group, the man was upset at U.S. support for Israel, and therefore was motivated by political disagreement. This led the FBI to classify this shooting as a terrorist act, one of the first on U.S. soil since the September 11 attacks.
On September 21, 2005, JetBlue Flight 292, an Airbus A320 discovered a problem with its landing gear as it took off from Bob Hope Airport in Burbank. It flew in circles for three hours to burn off fuel, then landed safely at Los Angeles International Airport on runway 25L, balancing on its back wheels as it rolled down the center of the runway. Passengers were able to watch their own coverage live from the satellite broadcast on JetBlue in-flight TV seat displays of their plane as it made an emergency landing with the front landing gear visibly becoming damaged. Because JetBlue did not serve LAX at the time, the aircraft was evaluated and repaired at a Continental Airlines hangar.
On August 16, 2007, a runway incursion occurred between WestJet Flight 900 and Northwest Airlines Flight 180 on runways 24R and 24L, respectively, with the aircraft coming within 37 feet (11 m) of each other. The planes were carrying a combined total of 296 people, none of whom were injured. The NTSB concluded that the incursion was the result of controller error. In September 2007, FAA Administrator Marion Blakey stressed the need for LAX to increase lateral separation between its pair of north runways in order to preserve the safety and efficiency of the airport.
On October 13 and 14, 2013, two incidents of dry ice bomb explosions occurred at the airport. The first dry ice bomb exploded at 7:00 p.m. in an employee restroom in Terminal 2, with no injuries. Terminal 2 was briefly shut down as a result. On the next day at 8:30 p.m., a dry ice bomb exploded on the ramp area near the Tom Bradley International Terminal, also without injuries. Two other plastic bottles containing dry ice were found at the scene during the second explosion. On October 15, a 28-year-old airport employee was arrested in connection with the explosions and was booked on charges of possession of an explosive or destructive device near an aircraft. On October 18, a 41-year-old airport employee was arrested in connection with the second explosion, and was booked on suspicion of possessing a destructive device near an aircraft. Authorities believe that the incidents were not linked to terrorism. Both men subsequently pleaded no contest and were each sentenced to three years' probation. The airport workers had removed dry ice from a cargo hold into which a dog was to be loaded, because of fears that the dry ice could harm the animal.
In the 2013 Los Angeles International Airport shooting of November 1, 2013, at around 9:31 a.m. PDT, a lone gunman entered Terminal 3 and opened fire with a semi-automatic rifle, killing a Transportation Security Administration (TSA) officer and wounding three other people. The gunman was later apprehended and taken into custody. Until the situation was clarified and under control, a few terminals at the airport were evacuated, all inbound flights were diverted and all outbound flights were grounded until the airport began returning to normal operation at around 2:30 p.m.
On August 28, 2016, there was a false report of shots fired throughout the airport, causing a temporary lock down and about 3 hours of flight delays.
On May 20, 2017, Aeroméxico Flight 642, a Boeing 737-800, collided with a utility truck on a taxiway near Runway 25R, injuring 8 people, two of them seriously.
On November 21, 2019, Philippine Airlines Flight 113, operated by a Boeing 777-300ER suffered an engine compressor stall shortly after take off from the airport's Runway 25R, forcing the flight to return. The flight made a successful emergency landing just 13 minutes after departure. There were 342 passengers and 18 crew onboard the flight, with no injuries reported.
Another popular spotting location sits under the final approach for runways 24 L&R on a lawn next to the WestchesterIn-N-Out Burger on Sepulveda Boulevard. This is one of the few remaining locations in Southern California from which spotters may watch such a wide variety of low-flying commercial airliners from directly underneath a flight path.
One can also do aircraft spotting at a small park in the take-off pattern that (normally) goes out over the Pacific. The park is on the East side of the street Vista Del Mar from where it takes its name, Vista Del Mar Park.
Numerous films and television shows have been set or filmed partially at LAX, at least partly due to the airport's proximity to Hollywood studios and Los Angeles. Film shoots at the Los Angeles airports, including LAX, produced $590 million for the Los Angeles region from 2002 to 2005.
