Avantair, the fractional operator flying an all-Piaggio Avanti fleet, took delivery last month of its 16th copy of the Italian-built twin-turboprop pusher. The Fairfield, N.J., company said it will continue to receive one Avanti per month through 2007, which will bring the planned fleet to nearly 50 aircraft by the end of that year. At press time the number of Avantair share-owners stood at 132.
