Charter group Falcon Aviation Services signed a letter of intent to buy a Bombardier CS300 yesterday, with an option for a second. Falcon Aviation Services will thus be the first non-airline operator of the CSeries, offering it for charter by private individuals and businesses. The $156.5 million deal, announced this week at the Air Expo show in Abu Dhabi, takes the total number of orders and commitments for the CSeries to 447, of which 201 are firm orders. The aircraft are to be supplied in an all business-class configuration, although the exact number of seats has yet to be specified.
