Flew its last service with the airline on 14Sep16 and was apparently stored at Buenos Aires Ezeiza (EZE) soon thereafter.  This example was delivered to Singapore Airlines on 24Apr96 and also flew for Cathay Pacific before joining Aerolineas on 08Jan12. 

Both of the above A340's will be replaced by one of the many A330's that Aerolineas is due to receive in the coming years.
