The airline uses the branding and corporate identity of JetSmart, its parent company, and operates a fleet of Airbus A320 aircraft with a base at Aeroparque Jorge Newbery in Buenos Aires.

[4] JetSmart Argentina received its air operator's certificate and its first aircraft, an Airbus A320-200 registered as LV-HEK, in December 2018.

[5][6] In February 2019, the airline announced and opened reservations for its first services beginning on 10 April 2019, which were to be operated from a new base at El Palomar Airport near Buenos Aires, after its parent company had previously operated flights to the airport from Santiago de Chile.

[7] The airline announced further expansion plans in August 2019, with Rosario as a new destination to launch in November 2019,[8] and that it would increase its Airbus A320 fleet to six aircraft.

In early 2021, it was reported that the airline would not return to El Palomar and instead relocate its services to Aeroparque, with operations at the airport and new base launching in March 2021.
