The two airports of El Tepual (Puerto Montt) and La Florida (La Serena) were part of the first privatisation wave in Chile. The concession for the airport El Tepual in Puerto Montt was renewed in 2007 and again awarded to the consortia led by A-port Operaciones S.A.. The concession in La Florida was prolonged for 5 years in 2007.
Since December 2011, the Cerro Moreno International Airport in Antofagasta, the second largest airport in Chile, belongs to the portfolio as well.
Flughafen Zürich AG participates indirectly through its affiliates A-port S.A. and A-port Operaciones S.A. in the three Chilean concessions.
