TAP Air Portugal

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 24.450 kilometres (15.193 mi; 13.202 nmi) 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. 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. 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.
