Aerolineas also retired another A340-313X, LV-CSE (c/n 126), when it departed Buenos Aires Ezeiza (EZE) to Victorville (VCV), California, USA on 05Nov17 where it was destined to be scrapped for spare parts.
This leaves Aerolineas Argentinas with three A340-313X's in its fleet, LV-CSF (c/n 128), LV-FPU (c/n 170), and LV-FPV (c/n 193) with LV-FPU flying the Buenos Aires Ezeiza (EZE) - Madrid (MAD) route on a regular basis lately, LV-FPV flying both the Madrid (MAD and Ushuaia (USH) routes and LV-CSF apparently inactive (all route data per flightradar24.com).
LV-FPU and LV-FPV are scheduled to leave the Aerolineas Argentinas fleet in late 2018 or early 2019 marking the retirement of the A340 from service with the Argentine national carrier.
