LAN Airlines is the flag carrier of Chile. Its main hub is Santiago National Airport. In 2012, LAN Airlines merged with the Brazilian TAM Airlines, creating the largest airline holding company in South America. The two carriers are slated to be fully integrated in 2018.

LATAM Airlines, which was formed from the LAN and TAM airline merger, is a Chile-based carrier that serves South America, Central America, North America, the Caribbean, Europe and Oceania. If you’re in North America, it can still pay to be a member of its frequent flyer program LATAM Pass, even if you don’t frequently fly to the south.
