Aer Arann are pulling the route because the PSO money is ceasing.
Also, the latest CAA stats would suggest there's about 6-8 people per flight, so her assertion that a lot of people depend on the route is incorrect.
The fact of the matter is, Loganair used to operate a reliable service at good times from LDY to DUB. Then RE came in and the route went down the pan rapidly. This morning is a case in point. The 9.20 arrival finally turned up at 11.39.
The route has been utterly decimated by poor timings, frequent delays and regular cancellations; so one has to wonder, which airline would be able to rebuild it?
