Aviation History
Portugal's aviation history includes some of Europe's oldest regional carriers, such as SATA founded in 1941 to serve the Azores, alongside the 1945 founding of TAP (Transportes Aéreos Portugueses), which became the national flag carrier. Portugal's neutrality in World War II made Lisbon an important transatlantic staging point in the early flying-boat era. TAP was nationalized after the 1974 Carnation Revolution, and its ownership has swung repeatedly since: partly privatized in 2015, renationalized in 2020 as part of a pandemic-era bailout, and put forward for reprivatization again in the mid-2020s. Portugal's low-cost carrier and charter market, including bases for major pan-European budget airlines, has grown substantially since the 1990s and 2000s.
A regional airline was established to serve the Azores archipelago, becoming one of Portugal's oldest continuously operating carriers.
Lisbon's Portela Airport (later renamed Humberto Delgado Airport) opened, becoming Portugal's principal international gateway.
Transportes Aéreos Portugueses was established, beginning commercial operations soon after and eventually becoming Portugal's flag carrier.
Following the 1974 Carnation Revolution, TAP was brought under full state ownership.
A majority stake in TAP was sold to a private consortium, though the deal was later partly unwound by the incoming government.
The Portuguese state took back majority control of TAP as part of a financial rescue during the COVID-19 pandemic's collapse in air travel demand.
The Portuguese government announced and began a process to sell a stake in TAP back to private investors, a process still unfolding.
