In addition to what Kupe says Delta will be putting the CS100 into service this fall and should have 20 airframes in service within a year. The aircraft was delayed by the Boeing lawsuit otherwise they would be entering service next month. It has truly unique capabilities for long flights off short runways. It could easily do EIS to JFK/ATL even if the runway was wet for departure. Sadly however initially the aircraft will be deployed for mostly short domestic routes. If however the BVI government wants non stops I suspect a subsidy for far less than 7 million would convince Delta to give EIS-ATL a try. London City Airport is for reference 4900 feet long and the aircraft is capable of transatlantic flights from there. London to NYC is 3000 miles. New York to the BVI is 1411 miles. JetBlue is rumored to be interested in the aircraft also. It would fit well in their system.
