Ladeco began operations in 1958 flying mostly internal routes between Chile's major cities and some international routes, and continued to run services until 1994 when LanChile (currently called LAN Airlines) bought over 99% of the shares and merged Ladeco into its fleet. At the time of takeover, Ladeco was equipped mainly with Boeing 737 aircraft as well as some Boeing 727s and Boeing 757s. Ladeco then became exclusively an internal carrier between Chilean cities. Its name has since disappeared and most internal routes are covered by an affiliate of LAN Airlines called LAN Express. Airlines fleet includes 20 Boeing 737-200, 7 Boeing 727, 4 BAC-111, 4 Boeing 707, 6 Douglas DC-6 B, 2 Boeing 757, 2 Boeing 737-300 and two Fokker 27 500 aircraft (Reg. CC CIS and CC CIT). and in the ´60s, numerous Douglas DC 3; Cargo fleet includes 3 Boeing 707 aircraft.
