I really don't think we will see anything like NYC or DXB from Bournemouth within ten years. There are so many other regional airports ahead of Bournemouth on the priority list. For either NYC or DXB or both ;
Aberdeen, Belfast Int'l, Bristol, Cardiff, Cork, Doncaster Sheffield, East Midlands, Edinburgh, Leeds Bradford, Liverpool, Newcastle, Stansted to name a few.
