I think the argument here is missing the key point that Knock has sustained a regular service to the English midlands for years and continues to do so throughout 2015. Shannon, on the other hand, has not been able to sustain a regular service to this region which is currently unserved from that airport. If such a large market existed for routes from Shannon to this region as is claimed I'm sure either Birmingham or East Midlands would be served at this time. Nonetheless, I'm sure some airline will make another attempt to operate a route to the region from Shannon in the future.
