TAP Air Portugal, formally Transportes Aéreos Portugueses (TAP), is the flag carrier of Portugal, headquartered at Lisbon Airport, which also serves as its main hub. Founded in 1945, the airline began commercial services the following year. It has been a member of Star Alliance since 2005.

TAP operates flights to destinations across Europe, the Americas, Africa, and Asia, with a particular focus on routes connecting Portugal with Brazil, Lusophone African countries, and other Portuguese-speaking markets. Its fleet consists entirely of Airbus aircraft, with regional services operated under the brand TAP Express using Embraer jets.

Throughout its history, TAP has alternated between public and private ownership. The airline was sold to a private consortium in 2015, before the Portuguese state gradually reasserted control, renationalising in 2020. The Portuguese government subsequently announced plans to reprivatise the airline, Portuguese Government to Sell TAP Portugal, Aviation Source News, Jamie Clarke, Retrieved 15.11.2022. a process which drew scrutiny from the Portuguese Court of Audits.

History Establishment and early operations

On 14 March 1945, the airline was founded as state-owned company with the name Transportes Aéreos Portugueses (Portuguese Air Transportation) and operated under the jurisdiction of the Portuguese Civil Aviation Office. Later that same year, it took delivery of its first aircraft, a pair of Douglas DC-3s. The airline began commercial services on 19 September 1946, performing an inaugural flight from Lisbon to Madrid, carrying a total of 11 passengers on one of its DC-3s. On 31 December 1946, TAP began its Linha Aérea Imperial, a twelve-stop colonial service including Luanda, Angola and Lourenço Marques (now Maputo), Mozambique. It covered within 15 days (both ways), making it the longest air service operated with twin-engine airliners at that time. To suit the tropical conditions at most of these destinations, a special uniform was adopted, comprising khaki shirts with either skirts or shorts.

In 1947, the airline launched its first domestic services, commencing a route between Lisbon and Porto, as well as another international route between São Tomé and London. That same year, a total of four Douglas DC-4 Skymasters were purchased; these reportedly remained in the airline's service as late as 1960. These were used on the routes to Africa and to major European destinations, including London. During 1948, new services to Seville and Paris were launched.

Privatisation During 1953, the airline was privatised for the first time in its history, reorganising from a public service to a public limited company (plc); that same year, it commenced new services to Tangier and Casablanca. During late 1955, several Lockheed Super Constellation four-engined pressurised airliners were acquired; these were immediately introduced on the TAP African scheduled services to Luanda and Lourenço Marques.Marson 1982, p. 258. The Super Constellation was credited with noticeably reducing flight times over prior airliners on its routes.

During 1955, the airline broke new ground with a successful long-distance experimental transatlantic trip to Rio de Janeiro, Brazil. On this flight, as a passenger, was the Portuguese aviator and cartographer Carlos Viegas Gago Coutinho. By the end of the decade, the firm had attained several milestones, including the carriage of 64,000 passengers, its fleet performing 10,000 hours of flight, a route network spanning 14,000 km, while also employing over 1,000 members of staff.

Beginning in 1960, TAP launched Rio de Janeiro as its first destination in Brazil, in a jointly-operated air service named "Voo da Amizade" ("Friendship Flight") with Panair do Brasil (1960–1965) and Varig (1965–1967). A route from Lisbon to Goa, a 19-hour flight with five stopovers, was added to the network during 1961.

The jet era – mid-1960s onwards

During July 1962, TAP entered the jet era, having procured an initial batch of three French-built Sud Aviation Caravelle, an early twin-jet airliner. These were first operated upon the airline's most competitive European routes.Chillon 1980, pp. 53–54. That same year, new services were launched between Lisbon and Las Palmas, as well as Santa Maria in the Azores. During 1963, additional European routes, serving Geneva, Munich, and Frankfurt, commenced.

On 19 June 1964, the one-millionth passenger was carried by the airline, broadly 18 years following the commencement of operations. During the following year, TAP procured its first Boeing-built jetliner, the 707. Two years later, it would be followed by the short-haul Boeing 727. On 17 June 1966, TAP operated its first sole flight to Brazil, one of its 707s landed at Galeão Airport in Rio de Janeiro at precisely at the same time and on the same day as when the hydroplane Santa Cruz moored in Guanabara Bay in 1922, when Sacadura Cabral and Gago Coutinho made their historic South Atlantic crossing. The route to Brazil was inaugurated.

In 1967, the airline achieved a milestone: it became the first European airline to fly exclusively with jets. In 1969, service to New York City via Santa Maria Island began; two years later, Boston was added to the New York service. During 1971, the airline opted to relocate its headquarters to Lisbon Airport. In the following year, TAP received the first of an initial batch of four Boeing 747-200s. In 1974, it became the first European airline to perform complete overhauls of the Pratt & Whitney JT9D turbofan engine, which powered early versions of the Boeing 747 amongst other aircraft. By the end of the decade, the airline operated a fleet of 32 modern airliners that served in excess of 40 destinations on four continents.

In 1974, TAP introduced a new computerised system handling reservations, load control, and check-in, known as Tapmatic. By the end of 1974, TAP had carried more than 1.5 million passengers, flown 68,210 hours over a network of almost 103,000 kilometres and had a staff of over 9,000.

Nationalisation Following the 25 April 1974 revolution, Portugal was caught up in the wave of nationalisations during the following year and TAP was no exception, thus becoming a state-owned corporation during 1975.

Following the independence of both Angola and Mozambique, the importance of the African market decreased tremendously; due to decreasing passenger demand, two of the 747s were sold on during 1976. During 1979, the airline launched a modernisation programme; amongst other brand changes, its name changed to TAP Air Portugal, which was deemed to be easier for international customers to recognise.

Fleet modernisation and expansion

In 1980, TAP launched a new service between Lisbon and Barcelona; operations were also expanded between Milan and Rome. During the following year, Teresa Carvalho became the airline's first female pilot; that same year, its first in-flight magazine, Atlantis, was launched. During 1985, the airline reportedly carried two million passengers within a single year for the first time; a museum dedicated to the airline was also opened on 14 March 1985 to mark the company's fortieth anniversary.

During the 1980s, the fleet of Boeing 707s and 747s was replaced with Lockheed L-1011 TriStars and Airbus A310s on long-haul routes. During 1983, TAP started operating its first Boeing 737-200s on short-haul routes. In 1988, it launched a new fare-calculation and ticketing system. That same year, it also became the first airline to harness land-to-air datalinks via a satellite connection.

During 1985, TAP established its charter subsidiary Air Atlantis, providing leisure flights to most European cities, which operated Boeing 707, Boeing 727 and Boeing 737 jetliners.

During 1991, the airline reportedly carried three million passengers that year for the first time. In 1993, TAP began flying to Tel Aviv. In 1994, TAP signed for a code sharing arrangement with Delta Air Lines for North Atlantic service; this agreement came to an end during 2005. 1996 saw the introduction of service to Boston via Terceira Island, the inauguration of service to Macau and the launch of TAP's website. In 1997, service began to Punta Cana and Bangkok; however, flights to Bangkok and Macau were discontinued during the following year.

By the late 1990s, TAP had expanded its fleet by selling its older Boeing 727s and Boeing 737s and replacing them with Airbus A319, A320 and A321 aircraft. Its TriStars were sold to Air Luxor and were replaced with Airbus A340s beginning in 1995. These changes led to TAP becoming an Airbus-only operator, which it claimed to have also made its fleet more economical and versatile. Furthermore, the airline had initiated a program of continuous cabin modernisation and renewal with the aim of implementing ever greater levels of service. In 1999, TAP introduced its first Blue Flights, upon which smoking was banned.

In 1997, a strategic alliance was formed between TAP and Swissair. Within the scope of this agreement, a team of professional managers arrived at TAP, led by the Brazilian Fernando Pinto. Part of the agreement would lead to Swissair buying a 34% stake of TAP. Also, TAP became a member of Qualiflyer, the frequent-flyer program led by the Swiss flag carrier. Due to financial difficulties, the Swiss company ended up not buying the agreed shares of TAP Air Portugal, unilaterally revoking the partnership agreement which led to unexpected costs for the Portuguese airline in 2000. This revocation culminated in legal action being taken by TAP against Swissair.

Start of the 21st century

In February 2005, TAP Air Portugal was re-branded TAP Portugal. On 14 March 2005, TAP became a member of the multinational Star Alliance, the same day the company celebrated its 60th anniversary. TAP also ended code-sharing with Delta Air Lines and began a new agreement with United, as part of its Star Alliance membership. Under this agreement, United's code (UA) is placed on TAP Air Portugal's transatlantic flights and some African flights, and TAP Air Portugal's code (TP) is placed on United flights.

In 2006, TAP Air Portugal signed a deal with Espírito Santo International to buy 99.81% of Portugália, a Portuguese regional airline. It also started a code-sharing with US Airways on all routes between Portugal and the United States with connecting services out of Newark and Philadelphia.

In 2007, NATO named TAP Air Portugal the Best Engine/Aircraft Source of Repair for NATO's AWACS Maintenance Program. TAP Air Portugal has complete maintenance and overhaul bases in Portugal (Lisbon) and Brazil (Rio de Janeiro and Porto Alegre) and has specialised line maintenance stations in three continents: 4 in Portugal, 8 in Brazil, and 1 in Angola. It started scheduled flights to Moscow, Warsaw and Helsinki, in June 2009.Easier Travel: TAP flies to Warsaw, Moscow & Helsinki retrieved 8 December 2008

After deciding to outsource its Passenger Service System in 2008, TAP migrated its reservation and inventory systems to the Altéa system managed by Amadeus. Before the migration, TAP had been using a system derived from Delta Air Lines called Tapmatic, in use since 1972.

In 2010, TAP introduced two new routes to Africa: Marrakesh and Algiers, the latter was discontinued in 2017. The launch of these new routes highlighted the airline's growth strategy for Africa, an important segment in the network where the airline has continually expanded since 2001, going from 236,000 to 541,000 passengers, an increase of more than 129%. In 2011, new long range routes to both Miami and Porto Alegre were introduced.
