An airline is an organization that provides a regular public service of air transportation on one or more routes. Traveling by air is much faster and less accident-prone than other methods of travel.
Humans have been flying since 1903 when the Wright Brothers took to the air. Of course, the aviation business started later – with the first registered passenger flights in 1914 [across Tampa Bay, Florida].
Amazingly, for an industry known for its volatility and financial instability, quite a few companies of these early heroic aviation years still survive in their original form.
Though it may seem a completely modern enterprise, commercial air transport has been around for over a century.
