Venezuelan state-owned airline Conviasa is to open a new route between Caracas and Buenos Aires Ezeiza airport in Argentina.
The Buenos Aires service, due to launch on 21 May, will be Conviasa's first international operation within South America.
A Conviasa source says that the service will be operated twice weekly - on Fridays and Sundays - using Airbus A340-200 aircraft.
The Venezuelan carrier will cooperate with Aerolineas Argentinas on the route, with the latter already operating four flights per week between the two cities. However, an Aerolineas source specifies that there is "no formal commercial alliance" between the carriers.
Aside from some regional Caribbean routes, Conviasa's only existing international destinations are Damascus in Syria and Teheran in Iran, served by its only long-haul aircraft type, the A340.
