landing at 08:45 local time, followed by a round trip flight from Buenos Aires to Mendoza and a second daily frequency to Córdoba. In April 2019, following the grounding of the Norwegian Group's Boeing 737 MAX 8 aircraft, the airline transferred one of its Boeing 737-800 aircraft back to Norwegian Air International to assist with the Norwegian Group's operations in Europe. In June 2019, the airline announced service to five additional destinations from Buenos Aires Aeroparque to begin from September 2019, consisting of Comodoro Rivadavia, Puerto Madryn, San Salavador de Jujuy, Trelew, and Ushuaia, however by September 2019, only the routes to San Salvador de Jujuy and Ushuaia ultimately launched. Following the departure of Bjørn Kjos as parent company Norwegian Air Shuttle's CEO in July 2019, interim CEO Geir Karlsen stated that Norwegian Air Argentina's operations would be reviewed, with an August 2019 deadline for financial results to improve, and tickets for flights were not sold beyond 28 March 2020. On 4 December 2019, Norwegian Air Argentina was sold for an undisclosed amount to Indigo Partners subsidiary and Chilean low-cost airline JetSmart, which took over operations of the airline with immediate effect. For the months following the sale, JetSmart had planned to phase out the Norwegian brand and integrate the airline with its own Argentine airline JetSmart Argentina. Norwegian Air Argentina's three Boeing 737 aircraft, owned by Norwegian Air Shuttle but registered in Argentina, were not among the company's assets sold to JetSmart, and were planned to be returned to Norwegian's Europe-based operations while JetSmart would instate Airbus A320 family aircraft in their place. In the months following the transfer of most of Norwegian Air Argentina's assets and operations to JetSmart in December 2019, JetSmart had wet-leased Norwegian's Boeing 737s to operate the airline's flights at Aeroparque while renaming the company to "JetSmart Regional". This was in contrast to JetSmart's operations at El Palomar Airport, which were separately listed as being operated by JetSmart Argentina, until JetSmart would launch its own A320 services at Aeroparque. JetSmart had also encountered obstacles during Norwegian Air Argentina's integration with JetSmart's own Argentina-based operations, including disagreements with unions representing Norwegian's employees over new job contracts following the retaining of their employment in the transfer, and that Argentina's Civil Aviation Administration had not yet authorized the transfer of Norwegian's route authorities to JetSmart Argentina in time for the return of Norwegian's 737s to Europe by
