SATA Air Açores is a regional air carrier operating inter-island services within the Azorean Archipelago and its nine islands. SATA Air Açores was established in 1941 and started operations on 1947. The regional airline operates around 15,000 inter-island flights per year (in a normal year such as 2019 – for the year 2020 due to COVID-19, we expect around 10,000 inter-island flights).

The air carrier also operates wet lease flights between the Azores and Madeira Archipelagos on a regular basis for Azores Airlines as well as ad-hoc charter flights. The airline also provides a variety of aviation support services.
