Ryanair was founded in 1985. In 1991, Michael O'Leary was tasked with increasing its profitability. He quickly implemented faster aircraft turn-around, a "no frills" approach to economy class and no business class. In 2000 the airline launched its online booking system.  Passenger numbers rose and have grown by up to 25% a year since then. Ryanair carried fewer than 700,000 passengers annually in the 1980s but had 72 million customers in 2010. It also flies to over 150 destinations. Twenty percent of its revenue comes from optional extras - i.e. from sources other than air tickets. A leading consumer magazine said the airline was the "worst offender" for charging for optional extras. Ryanair argues this allows passengers who do not require these services to travel for the lowest possible price, thus giving customers the flexibility to choose what they pay for.
