Deutsche Lufthansa AG (), trading as Lufthansa Group, is a German aviation holding company. Its principal airline, Lufthansa German Airlines (branded as Lufthansa) is the flag carrier of Germany. Lufthansa Group is the second-largest airline group in Europe by passengers carried, as well as largest in Europe and fourth largest in the world by revenue. Lufthansa Airlines is also one of the five founding members of Star Alliance, the world's largest airline alliance, established in 1997.

Lufthansa Group owns several other airlines, including Austrian Airlines, Brussels Airlines, Discover Airlines, Eurowings, ITA Airways, and Swiss International Air Lines. The group also owns several aviation-related companies, including Global Load Control, Lufthansa Consulting, Lufthansa Flight Training, Lufthansa Systems and Lufthansa Technik.

The modern Deutsche Lufthansa AG was founded as Aktiengesellschaft für Luftverkehrsbedarf (Luftag) on 6 January 1953 by staff of the former Deutsche Luft Hansa, Germany's national airline founded in 1926. While Deutsche Luft Hansa played a significant role in the development of commercial aviation in Germany, it was liquidated in 1951 due to its association with the Nazi regime during World War II. Luftag adopted the branding of the former flag carrier by acquiring the Luft Hansa name and logo in 1954.

The corporate headquarters of Deutsche Lufthansa AG are in Cologne, Lufthansa's main operations base, the Lufthansa Aviation Center, is located at Frankfurt Airport, the airline's primary hub. The airline also maintains a secondary hub at Munich Airport, along with its Flight Operations Centre.

History 1950s: Post-war (re-)formation

Lufthansa traces its history to 1926 when Deutsche Luft Hansa was formed in Berlin by the merger of Deutscher Aero Lloyd, the world's sixth-oldest airline, and Junkers Luftverkehr. Deutsche Luft Hansa was Germany's flag carrier until the outbreak of war when it came under the command of the Luftwaffe. During the war, the airline was focused mainly on aircraft maintenance and repair in which forced labour was employed on the site of Berlin Tempelhof Airport. Following the surrender of Germany and the ensuing Allied occupation of Germany, all aircraft in the country were seized and Deutsche Luft Hansa was dissolved. The remaining assets were liquidated on 1 January 1951.

In an effort to create a new national airline, a company called Aktiengesellschaft für Luftverkehrsbedarf (Luftag) was founded in the city of Cologne in West Germany on 6 January 1953, with many of its staff having worked for the pre-war Deutsche Luft Hansa.

West Germany had not yet been granted full sovereignty over its airspace, so it was not known when the new airline could become operational. Nevertheless, in 1953, Luftag placed orders for four Convair CV-340 and four Lockheed L-1049 Super Constellations aircraft and set up a maintenance base at Hamburg Airport. On 6 August 1954, Luftag acquired the name and logo of the liquidated Deutsche Lufthansa for (equivalent to € today), thus continuing the tradition of a German flag carrier with that name.

On 1 April 1955, Lufthansa won approval to commence operation of scheduled domestic flights. The airline's initial network linked Hamburg, Düsseldorf, Frankfurt, Cologne, and Munich. International flights started on 15 May 1955, to London, Paris, and Madrid, followed by Super Constellation flights to New York City from 1 June of that year, and across the South Atlantic from August 1956.

However, the political realities of the time presented challenges for the airline. The United States, Soviet Union, Britain and France did not allow Lufthansa to fly to any part of the divided Berlin during the division of Germany. The airline had hoped this would only be a temporary matter and planned to move its headquarters and primary hub back to the German capital once the political situation changed, plans that ultimately never came to fruition, even after the lifting of these restrictions owing to German reunification in 1990 and the opening of the new Berlin-Brandenburg Airport in 2020. Instead, Lufthansa turned Frankfurt Airport into its primary hub in 1958.

The airline also embarked on a marketing campaign to encourage travelers to consider visiting West Germany as it rebuilt in the wake of World War II and to use its hub to connect to other locations across Europe. By 1963, the airline, initially limited in its public relations efforts, had become a major purveyor of West Germany's image abroad.

During this time, East Germany attempted to establish its own "Lufthansa" airline in 1955, but legal challenges from the West German carrier led to its abandonment. East Germany subsequently launched Interflug as its national carrier in 1963.

1960s: Introduction of jetliners

Lufthansa embraced the jet age in 1958 by ordering four Boeing 707 aircraft. This marked a significant leap forward, allowing them to launch jet flights between Frankfurt and New York City in March 1960. To further bolster their jet fleet, Boeing 720B aircraft (a 707 derivative for shorter flights from shorter runways) were later acquired.

Lufthansa's network continued to expand throughout the early 1960s. In February 1961, their Far East routes extended beyond Bangkok to include Hong Kong and Tokyo. Africa saw additions in 1962 with Lagos, Nigeria, and Johannesburg, South Africa joining the network.

Innovation continued with the introduction of the Boeing 727 in 1964. This enabled Lufthansa to launch a pioneering Polar route from Frankfurt to Tokyo via Anchorage in May of that year. Further expansion plans were solidified in February 1965 with the order of twenty-one Boeing 737 aircraft, entering service in 1968.

Lufthansa's role in Boeing's history is noteworthy. They hold the distinction of being the first customers for the Boeing 737 and one of only four buyers of the initial 737-100 model (alongside NASA, Malaysia-Singapore Airlines, and Avianca). While NASA technically had the first built 737 airframe, it was ultimately delivered last and originally intended for Lufthansa, making them the first foreign launch customer for a Boeing airliner.

1970s–1980s: The wide-body era

The wide-body era for Lufthansa started with a Boeing 747 flight on 26 April 1970. It was followed by the introduction of the DC-10-30 on 14 January 1974, and the first Airbus A300 in 1976. In 1979, Lufthansa and Swissair became launch customers for the Airbus A310 with an order for 25 aircraft.

The company's fleet modernisation programme for the 1990s began on 29 June 1985, with an order for fifteen Airbus A320s and seven Airbus A300-600s. Ten Boeing 737-300s were ordered a few days later. All were delivered between 1987 and 1992. Lufthansa also bought Airbus A321, Airbus A340, and Boeing 747-400 aircraft.

In 1987, Lufthansa, together with Air France, Iberia, and Scandinavian Airlines, founded Amadeus, an IT company (also known as a GDS) that would enable travel agencies to sell the founders and other airlines' products from a single system.

1990s–2000s: Further expansion Following German reunification on 3 October 1990, Lufthansa swiftly reintegrated Berlin into its network, marking the city's return as a key destination within 25 days.

The mid-1990s saw a period of strategic restructuring for Lufthansa. This involved the establishment of independent operating companies within Lufthansa Group, specializing in areas like maintenance (Lufthansa Technik), cargo (Lufthansa Cargo), and information technology (Lufthansa Systems). Over time, the group further expanded through the addition of LSG Sky Chefs (catering), Condor (leisure travel), and Lufthansa CityLine (regional operations).

Lufthansa joined Air Canada, Scandinavian Airlines, Thai Airways International, and United Airlines to form Star Alliance on 14 May 1997, the world's first multilateral airline alliance.

Lufthansa actively addressed its historical legacy during this period. In 1999, the airline participated in a German initiative aimed at resolving wartime misdeeds, acknowledging the use of forced labor by its predecessor, Deutsche Luft Hansa. As part of the initiative, Lufthansa also reportedly paid tens of millions of German marks. Additionally, a historical study was commissioned to shed light on this aspect of the company's past. However, Lufthansa was criticised for not publishing the resulting study for more than a decade.

The early 2000s witnessed Lufthansa demonstrate remarkable resilience in the face of industry challenges. Despite significant industry losses following the 11 September attacks, the airline maintained profitability and strategically avoided workforce reductions. Lufthansa became the launch customer for the Connexion by Boeing in-flight internet connectivity in 2004.

Lufthansa further solidified its position as a major European airline group through strategic acquisitions. The acquisitions of Swiss International Air Lines in 2005, Brussels Airlines (staged between 2009 and 2017), and Austrian Airlines in 2009 expanded the group's reach and network capabilities.

At the end of the 2000s, Lufthansa made a large commitment to very large aircraft, introducing the first of 14 Airbus A380 in 2010 and becoming the launch customer for the Boeing 747-8I in 2012, eventually purchasing 19 of the type.

2010s: Losses and strikes In 2011 Lufthansa planned significant growth at Berlin Brandenburg Airport for the originally planned opening in 2012 with many new connections from Berlin.

After a loss of 298 million euros in the first quarter of 2010 and another 13 million loss in the year 2011 due to the economic recession and restructuring costs, Deutsche Lufthansa AG cut 3,500 administrative positions or around 20 percent of the clerical total of 16,800 in 2012. Lufthansa announced a restructuring program called SCORE to improve its operating profit. As a part of the restructuring plan, the company started to transfer all short-haul flights outside its hubs in Frankfurt, Munich, and Düsseldorf to the company's re-branded low-cost carrier Germanwings.

In September 2013, Lufthansa Group announced its biggest order, for 59 wide-body aircraft valued at more than 14 billion euros at list prices. Earlier in the same year, Lufthansa placed an order for 100 next-generation narrow-body aircraft.

The group has had a long-standing dispute with the Vereinigung Cockpit union, which has advocated for a system in which pilots can retire at the age of 55, and 60% of their pay be retained. Lufthansa pilots were joined by pilots from the group's budget carrier Germanwings to stage a nationwide strike in support of their demands in April 2014 which lasted three days. The pilots staged a six-hour strike at the end of the summer holidays in September 2014, which caused the cancellation of 200 Lufthansa flights and 100 Germanwings flights.

During the course of the 2014 FIFA World Cup, part of the fleet was branded "Fanhansa".

In November 2014, Lufthansa signed an outsourcing deal worth $1.25 billion with IBM that will see the US company take over the airline's IT infrastructure services division and staff.

Carsten Spohr, Lufthansa's CEO, called the March 2015 Germanwings Flight 9525 crash, "the darkest day for Lufthansa in its 60-year history", when co-pilot Andreas Lubitz intentionally flew an aircraft into a mountain, killing himself, 144 passengers and 5 crew members. Nonetheless, damage control by Spohr and his team was poor according to several sources. It was revealed that Lubitz suffered from a severe case of depression and mental disorders and had intentionally crashed Germanwings Flight 9525 into the French Alps, killing all 150 aboard whereas Spohr had misleadingly said the co-pilot "was 100% airworthy without any restrictions, without any conditions".
