Developments: 2. In late July 2026, low‑cost carrier JetSMART announced two major moves in Argentina. It unveiled a new direct Buenos Aires‑Medellín service slated to begin on 12 November, adding five weekly flights that will link the Argentine capital with Colombia and feed into its broader South American network. At the same time, the airline launched operations in the province of Santiago del Estero, with officials highlighting expected benefits for tourism, business travel and regional integration. A few days later, in early August, JetSMART confirmed another domestic expansion: a new route connecting Posadas in Misiones Province with Buenos Aires, scheduled to start on 1 November. The provincial government highlighted the route’s role in boosting tourism and investment, and announced airport upgrades at Posadas to handle the increased traffic. Together, these announcements illustrate JetSMART’s rapid rollout of new international and intra‑Argentine flights aimed at enhancing connectivity and stimulating economic activity across the country. ## Timeline ### 2026-08-03: Misiones Province Secures New JetSMART Route to Buenos Aires Starting Nov 1 Misiones governor and tourism minister confirmed JetSMART will launch a Posadas‑Buenos Aires flight on Nov 1, with tickets from AR$46,300, aiming to boost tourism and the provincial economy. 2 sources. https://clstr.news/cluster/misiones-province-secures-new-jetsmart-route-to-buenos-aires-starting-nov-1 ### 2026-07-30: JetSMART adds Buenos Aires‑Medellín flights and launches service in Santiago del Estero JetSMART will start Buenos Aires‑Medellín flights on 12 Nov with five weekly services and has opened a new low‑cost route in Santiago del Estero, aiming to boost regional connectivity and tourism. 3 sources. https://clstr.news/cluster/jetsmart-adds-buenos-airesmedelln-flights-and-launches-service-in-santiago-del-estero --- Cite as: JetSMART expands Argentine network.
