The Story of RyanAir

RyanAir is an Irish budget airline. One of the largest in Europe in its class. Founded in 1985 and named after its founder, Irish businessman Tony Ryan. It is not known what way Ryanair would have developed if it was not for the 1991 restructuring decision, which was carried out to reduce costs and increase profitability.
