when did private jets and commercial airlines start

The history of private jets and commercial airlines can be traced back to the early 20th century. **Commercial Airlines:** - The origins of commercial aviation date back to the 1910s. The first scheduled airline service is generally considered to have started on January 1, 1914, when the St. Petersburg-Tampa Airboat Line in Florida began operating a flying boat service between the two cities. - Commercial aviation began to expand significantly after World War II, when advancements in technology made air travel faster and more reliable. The introduction of the Douglas DC-3 in the 1930s revolutionized air travel, making it more accessible. **Private Jets:** - The concept of private aviation began in the 1920s and 1930s with the development of smaller aircraft intended for personal use. - The first true business jet is often cited as the "de Havilland Dragon Rapide," which began service in the late 1930s. - The modern age of private jets began with the introduction of the Learjet 23 in 1963, which popularized the idea of flying for business on a private jet. Overall, both segments of aviation have evolved significantly since their inception, growing into important parts of modern transportation.
