LATAM's oldest root is LAN, founded in 1929. A Chilean air force commodore, Arturo Merino Benitez, set it up as Linea Aeropostal Santiago-Arica. The state-owned carrier flew airmail, so it carried letters rather than tourists. Its route ran north from the capital to Chile's far edge. The airline was later renamed Linea Aerea Nacional and became one of South America's most respected carriers. Private owners took over in 1989.
Under the Cueto family, LAN grew quickly in the 1990s and 2000s. It added airlines in Peru, Argentina, Ecuador, and Colombia. It also joined oneworld. An alliance like that is a group of airlines that share routes and benefits with each other. Then came the 2012 merger with Brazil's TAM, founded in 1976. The deal created LATAM Airlines Group, by far the largest airline group in Latin America.
Delta Air Lines bought a 20 percent stake in 2019, and LATAM left oneworld in 2020. That same year the pandemic pushed the group into Chapter 11 protection in New York. It emerged in November 2022, leaner and profitable. LATAM now leads home markets in Chile, Brazil, Peru, Ecuador, and Colombia, and flies long routes to North America, Europe, Africa, and Oceania. A joint venture with Delta links both continents.
