AlitaliaCompagnia Aerea Italiana S.p.A. (), operating as Alitalia, is the flag carrier and national airline of Italy, which took over the name, the landing rights, many planes and some other assets from the liquidation process of the old Alitalia — Linee Aeree Italiane and the entire Air One. The company has its head office in Fiumicino, Italy. Its main hub is Leonardo da Vinci-Fiumicino Airport, Rome. Alitalia is Italy's biggest airline, and the world's 19th. The name "Alitalia" is an Italian portmanteau of the words ali (wings), and Italia (Italy). In late 2013, facing bankruptcy, the loss of a major fuel supplier, and a possible grounding by Italy's civil aviation authority, the airline announced a €500 million rescue package which includes a €75 million investment by the Italian state-owned postal operator.
