The history of RyanAir is one of innovation and success. Founded in 1985 by Tony Ryan, the airline was initially created to provide an affordable and efficient way for people to travel from their home countries in Europe to other parts of the continent. RyanAir has since become one of the most successful budget airlines in the world, with an expansive network that spans over 200 destinations in 37 countries.

The first milestone in RyanAir's history was in 1986 when the airline purchased its first aircraft, a Boeing 737-200. This marked the beginning of an era of growth for the airline, as it began to purchase more aircraft and expand its route network. By 1990, RyanAir had a fleet of eleven Boeing 737s and had expanded its operations to include routes to Spain, France, Germany, and the United Kingdom.

In 1997, RyanAir made the transition to a low-cost carrier model. The airline began to offer cheap tickets, no-frills service, and a simplified booking process. This move proved to be a success, and RyanAir's passenger numbers began to skyrocket. By 2003, the airline was carrying 28 million passengers and had become the largest budget airline in Europe.

In 2009, RyanAir experienced its first major incident when one of its aircraft crashed in France. The crash resulted in the death of two passengers and the injury of two more. RyanAir launched an investigation and subsequently implemented a number of safety measures to reduce the risk of future accidents.

In 2014, RyanAir entered the digital age when it launched its mobile app. The app allowed passengers to book flights, check in, and receive updates on their flights. This move proved to be a success, and the app now has over 25 million downloads.

In 2016, RyanAir took a major step forward in its evolution when it announced plans to expand its fleet to include larger aircraft. The airline purchased 175 Boeing 737 MAX aircraft which will be used to expand its route network and increase its capacity.

The most recent milestone in RyanAir's history came in 2018 when the airline became the first budget airline to offer trans-Atlantic flights. RyanAir now offers flights from Europe to the United States, Canada, and Mexico.

Over the course of its history, RyanAir has experienced a number of successes and setbacks. However, the airline has managed to remain a successful and profitable budget airline despite the challenges it has faced. RyanAir is now one of the most successful airlines in the world and is continuing to innovate and expand its operations.
