The story
The airline originally operated as JetSul. In 1998, however, it suspended its operations in order to restructure itself. In 2007, it started preliminary studies and tests. Cargo services started in July 2009, after receiving regulatory approval. It had codeshare agreements with Globex Cargo and Smart Cargo. In 2014, the Administrative Council for Economic Defense (CADE) approved the purchase of 49.99% by Brazilian Correios, but the purchase was not concluded. Rio Linhas Aéreas had night flight contracts to transport mail and packages for Correios (Brazilian Postal Service).
