Sky Airline, styled as SꓘY, is an airline based at Arturo Merino Benítez International Airport in Santiago, Chile. It is the second largest airline in the country behind flag-carrier LATAM Airlines and the first airline to operate under a low-cost model in the country. It serves international routes to Argentina, Brazil, Colombia, Peru and Uruguay. It also operates charter flights in Chile and South America and domestic flights within Peru.

Sky Airline was controlled by its founder, Jürgen Paulmann (1930–2014), a German-Chilean businessman, brother of retail billionaire Horst Paulmann.^[2] It started operations in December 2001 and made the first flights from Santiago to Northern Chile in June 2002. Since 2005 is a full member of IATA.

In April 2009, the company signed an agreement with Aerolíneas Argentinas, allowing the Argentinean flag carrier to offer in all its commercial offices and through its electronic ticket system most of the destinations covered by Sky Airline in Chile.^[3]

In 2011, it signed a codeshare agreement with TACA for domestic flights in Chile, Peru and between both countries.^[4] In 2012 it signed a codeshare agreement with TACA's parent company, Colombia's Avianca for operations between Chile and Colombia.^[4]

The airline planned to transition to a low-cost carrier model during 2015 and 2016 to reduce costs.^[5]

On June 28, 2023, it was announced that Avianca and Gol Linhas Aéreas Inteligentes plan to add Sky to their proposed Abra Group.^[6]

Sky Airline was named the Best Regional Airline in South America in the 2014, 2015 and 2016 Skytrax World Airline Awards.^[7][8]

• On July 18, 2012, at 5:08 PM local time, a Sky Airline Flight SKU 101, operated by a Boeing 737-200 Advanced, registration CC-CRQ, with 115 passengers and 6 crew members on board, en route from Antofagasta Cerro Moreno Airport to La Serena-La Florida Airport, aborted landing at La Serena touching the runway with its right hand wing, suffering substantial damage to the wing tip and flap fairing. The plane safely landed at Copiapó-Chamonate Airport at 5:47 PM with no injuries. Visibility conditions at La Serena were rapidly deteriorating at the time of the approach, but still good enough for a safe landing (6000 m. visibility). The plane was subsequently repaired.^[23]
• On October 14, 2015, a passenger on board SKU 112, an Airbus A319, filmed part of the plane's left engine cowling coming off as it took off from Santiago Airport en route to Chamonate Airport. The plane immediately returned to Santiago Airport and landed safely. No passengers were injured. A similar incident with the A319 had happened previously on a British Airways flight departing Heathrow Airport.^[24]
