The most economical airport option is Transfer Temuco, a reliable door-to-door shuttle service (CH$5000). An Uber runs CH$10,000 to CH$13,000 to the airport (30 to 45 minutes) and CH$2300 to CH$2900 to the bus terminal (15 minutes). Colectivo 11 and 111 Express go from downtown (Claro Solar) to the bus terminal (CH$500 to CH$600). Micro 7 heads to the terminal as well, from Diego Portales (CH$450).
Europcar (www.europcar.cl) and Avis (www.avis.cl), among others, rent cars out of the airport.
