On August 21, 1941, a group of investors that included Augusto Rebelo Arruda, José Bensaude, Augusto d'Athayde, Corte Real Soares de Albergaria, Albano de Freitas da Silva and the company Bensaude & Co. Lda. (through its managing director António de Medeiros e Almeida) established
Sociedade Açoreana de Estudos Aéreos Lda. (English:
Azorean Aviation Studies Company, Ltd.) to look into the feasibility of developing an inter-island airline that would link the
Azorean archipelago and continental
Portugal, and to obtain the government concession to do so. Augusto Rebelo Arruda eventually transferred his shares to Bensaude & Co. Lda. on September 15, 1947, although the first
Sociedade Açoreana de Transportes Aéreos (English:
Azorean Air Transport Company) flight occurred from
Santa Maria Airport in June 1947. Captain Marciano Veiga piloted the first flight at the controls of a twin-engine Beechcraft (named
Açor) with seven passengers. The Portuguese government granted a temporary concession to the airline, which operated mail, cargo and air passenger services between
São Miguel (Santana Field, until 1969),
Terceira (at
Achada,
Lajes) and
Santa Maria airports. By May 23, 1948, the airline had received two
de Havilland DH.104 Dove aircraft to supplement its operations. On August 5, 1948, one of these Beechcraft failed to take to the air and crashed on take-off: all the passengers and crew were killed, prompting the suspension of flight operations. Two new DH.104 Doves would be delivered on May 23, 1949, with the capacity for nine passengers, and a
Douglas DC-3 Dakota (CS-TAD) with capacity for 26 passengers would enter into by July 1, 1964. In 1969, Nordela Airport (which would eventually be rechristened João Paulo II International) in Ponta Delgada (Relva) was inaugurated to civil traffic and would become the SATA base of operations. By 1971,
TAP Air Portugal would begin Lisbon-Ponta Delgada service, and the airport in
Horta,
Faial would be inaugurated on August 24, 1971. The airline would eventually replace its aging fleet with
Hawker Siddeley HS 748 turboprops (1972) with a larger capacity and range, that would fly between the newer airports constructed in all nine islands of the archipelago (between 1981 and 1983). In 1976, the
Portuguese Air Force offered two
Douglas DC-6 airplanes with a continental range. They were to be used effectively during a TAP strike that allowed SATA to extend their services to Lisbon. By April 14, 1977, it would have transported 1 million passengers throughout the regional market. It was originally formed as a private company (50% interest held by Bensaude & Co.Lda.), but on 17 October 1980, it was reborn as a state-owned enterprise (SOE) operated by the
Regional Government and TAP Air Portugal. It became a signatory of the
European Regions Airline Association (ERA) and the
International Air Transport Association (IATA) charters in 1980 when it became an SOE, which it remains as of March 2014. The name of the airline changed in 1980 to SATA Air Açores. Between 1989 and 1990, the inter-island
HS 748 aircraft were gradually replaced by
BAe ATP, after the first aircraft (named
Santa Maria) entered service in 1989. Eventually, other planes would be added, reflecting the regional politics, each aircraft would be named after an island (
Flores, in 1990, and
Graciosa, in 1991), including a small
Dornier 228-212 that was added to link the
small island of Corvo, which substituted a
CASA C-212 Aviocar Series 100 operated by the
Portuguese Air Force. A revitalization program was initiated in the late part of the 2000s to rationalize and upgrade existing aircraft, resulting in a competition between ATR and Bombardier to supply the necessary equipment that met the needs of the archipelago. The decision to purchase Bombardier NextGen aircraft was not without controversy. The latest phase of its fleet renovation, which complies with a 15–20 year plan, began in July 2009, with the entry into service of two Bombardier Q200. It was followed up with a ceremony in
Toronto,
Ontario, on 25 January 2010, when the first
next-generation Bombardier Q400, registration CS-TRD, was unveiled. The first of a series (four in all) began arriving at the end of January 2010; the second, registration CS-TRE, was received on 11 February, and the remaining planes arrived in March (registered CS-TRF and CS-TRG). The Q400 aircraft were projected for the short distance, high-density markets with the archipelago and
Macaronesian destinations. Its two PW150A engines, allows the planes to cruise at , while transporting 80 passengers comfortably for distances up to , markedly within the limits of the archipelago. ==Livery==
