if BA can get an airbus out of LCY to the USA, an airbus out of Ronaldsway to Europe can't be beyond possibility
Not beyond possibility but IOM will always suffer as every island does from a limited passenger base. The best option for routes into Europe will come from Flybe using the Q400, which in the current ecomic climate would make any new route launch less of a risk than using a higher capacity, higher cost aircraft.
