Airlines have changed a lot over time. In the early days, some used airships. These were very large flying machines. One airship even flew across the Atlantic Ocean in 1919. 
Many airlines are very old. A Dutch airline called KLM is the oldest. It still uses its original name today. 
Today, many airlines work in groups. These groups are called alliances. They help travelers by sharing services. They might share lounges, which are waiting rooms. They also share flight routes. This makes it easier to travel far away.
An airline is a company that provides air transportation. They use aircraft to move passengers or freight, which is another word for cargo. Some airlines only focus on moving freight. Other airlines carry passengers and also keep cargo in the belly of the plane. To operate, these companies must have an air operating certificate. This is a license from a government aviation body. Airlines can be scheduled or they can be charter operators. 
How an airline works has changed over many years. Before the 1930s, most airlines were owned by individuals. From the 1940s to the 1980s, many major airlines were owned by governments. After the mid-1980s, many became private companies again. 

Flying companies have a very long history. The first commercial passenger airline was called DELAG. It was founded on November 16, 1909. It used airships made by the Zeppelin Company. 
Many famous airlines grew from these early days. The Dutch airline KLM was founded on October 7, 1919. It is the oldest airline still using its original name. 

Traveling by air connects different parts of the world. Early airlines helped people reach far-away places. For example, Imperial Airways helped connect the British Empire. 

An airline is a commercial company that provides regular air transportation. These companies use aircraft to transport passengers or freight, which is another name for cargo. Many passenger airlines also carry cargo in the belly of their planes. Some airlines are dedicated solely to freight transport. To operate legally, airlines must hold an air operating certificate. This is a license issued by a governmental aviation body. Airlines can function as scheduled operators or as charter operators. 
Ownership of airlines has changed significantly over the last century. Before the 1930s, most airlines were owned by individuals. From the 1940s through the 1980s, many major airlines were owned by governments. Following the mid-1980s, there was a shift toward large-scale privatization. Since the 1980s, a trend of major mergers has emerged. Airlines often form partnerships called alliances to coordinate services. These alliances include Star Alliance, SkyTeam, and Oneworld. They manage passenger programs like lounges and frequent-flyer rewards. They also use codesharing, where two airlines offer the same flight. 
The history of commercial aviation began in the early 1900s. The world's first commercial passenger airline was DELAG. It was founded on November 16, 1909. DELAG operated airships made by the Zeppelin Company. Another very old company was the Compagnie générale transaérienne, or CGT. CGT was founded on October 10, 1909. It began cargo operations in April 1911. It started regular passenger services in March 1913. These were weekly return flights using fixed-wing aircraft. CGT later merged with other companies to become Air France. 
Early European aviation saw many companies form and merge. In 1916, George Holt Thomas formed Aircraft Transport and Travel. This company was an early predecessor of British Airways. In 1919, the Dutch airline KLM was established. KLM is the oldest airline still operating under its original name. In 1924, Imperial Airways was formed through a merger of several companies. This allowed British airlines to compete with French and German carriers. Imperial Airways pioneered routes to serve the British Empire. In 1933, several French airlines merged to create Air France. 
In Germany, several important airlines shaped aviation history. Junkers Luftverkehr began operations in 1921. It was a division of the Junkers aircraft manufacturer. In 1926, Deutsche Lufthansa was created by a merger. Lufthansa became a major investor in airlines outside of Europe. Germany also used airships for passenger service. The airship Graf Zeppelin offered scheduled flights to South America starting in 1931. The Hindenburg also entered passenger service in 1936. It successfully crossed the Atlantic 36 times before its crash in 1937. 
During the Soviet era, Aeroflot became a massive organization. By the end of the 1930s, it was the largest airline in the world. It operated approximately 3,000 aircraft. The airline employed over 4,000 pilots and 60,000 service personnel. Aeroflot was the only air carrier in the Soviet Union. On September 15, 1956, it became the first airline to operate sustained regular jet services. It used the Tupolev Tu-104 for these flights. 
Modern aviation has been shaped by deregulation. In the early 1990s, the European Union deregulated its airspace. This led to a rise in budget airlines like EasyJet and Ryanair. These companies grew quickly on shorter routes. Many traditional national airlines have also been privatized. For example, British Airways and Aer Lingus underwent privatization. Changes in oil prices also impacted airlines, such as in 2008 with Alitalia. Today, airlines continue to connect the world through massive networks.
