Aerolineas' A330-200's are progressively replacing the carrier's seven-strong A340-300 fleet. One of the latter aircraft, LV-CEK (c/n 094), flew its last revenue flight with Aerolineas on 14Aug16 and will be returned to the lessor once it has been refurbished. Of the other six A340's, LV-CSE (c/n 126), is expected to leave the fleet in mid-September with LV-CSX (c/n 373) scheduled to follow in March 2017.
Replacement A330's include the newly-delivered LV-GHQ, plus LV-GKO (c/n 587) and LV-GIF (c/n 1748) due to join Aerolineas in late August and October 2016, respectively.
Eventually, Aerolineas' entire A340 fleet might be replaced by A330's but a lot of that depends on whether the A330's will be able to operate some of Aerolineas' longest routes, such as Buenos Aires Ezeiza (EZE) - Rome (FCO) nonstop, which is currently covered by the A340's.
