Alitalia has ordered 5 747-400 during the Aerosalon this year together with an order for 6 ERJ-145 plus 10 options. They haven´t ordered the 744 together with KLM!!! And concerning the 717 rumour: this is not likely to become true. They already have a large AI fleet consisting of A320/321 and the A318 would be the most likely addition together with some A319. The next big fleet decisions will be how the MD-11 will be replaced. This order will be made together with KLM and probably Northwest. At the moment they consider the 330-200/-300 and 340-300/-500/-600 and the 767-400 777-200(X)/-300(X). It seems as if the busses are prefered.
