Airbus says aircraft leasing company IFLC has made a firm order for 50 single-aisle A320neo jets, which represents a robust start for the European plane maker at the Paris Air Show. Financial details were not disclosed Monday. However, the planes have a list price of $100 million but customers often negotiate steep discounts. The A320neo, a more fuel-efficient model than the original and widely used A320, was the star of the last Paris Air Show, according to AP. This year Airbus is hoping to attract attention to its new wide-body A350 aircraft. Airbus' Fernando Alonso said the plane's maiden flight last Friday went exactly as the simulator had predicted, and just like Airbus planes currently in operation. Once again, the air show is expected to showcase the Airbus-Boeing rivalry.
