* Santiago (SCL) - San Juan (UAQ) - eff 08Sep16 - 06Dec16
LATAM Chile operated this route 10x/weekly using A320's as a replacement for its normal Santiago (SCL) - Mendoza (MDZ) service while the latter airport was closed three months for major renovations, including to its runway. To the best of this blog editor's knowledge, this is the first and only time that San Juan (UAQ) has had scheduled international service.
* Sao Paulo Guarulhos (GRU) - Buenos Aires Ezeiza (EZE) - Bogota (BOG) - eff 15Dec16
Interestingly, LATAM Brazil operates this route and not LATAM Argentina. They fly it 5x/weekly using 767-300's.
* Buenos Aires Ezeiza (EZE) - Belo Horizonte (CNF) - eff 06Mar17
Azul Brazilian Airlines will start service to Argentina in March 2017 with flights from Buenos Aires to Belo Horizonte using ERJ 195's on a 1x/daily basis.
