Sky Airline is a Chilean low-cost carrier founded in 2001 and headquartered in Santiago, Chile. Originally operating as a charter and regional carrier, the airline transitioned to a full low-cost model around 2018, competing directly with other budget carriers in the South American market. The airline operates scheduled domestic routes throughout Chile as well as international routes to several South American destinations including Peru, Colombia, Argentina, and Brazil. Sky Airline has grown steadily since its rebranding and is considered one of Chile's primary low-cost carriers alongside JetSMART. Sky Airline is known for its unbundled fare structure, allowing passengers to purchase only the services they need. The carrier has invested in modernizing its fleet with fuel-efficient narrow-body aircraft to reduce operating costs and emissions.
