The only real carrier likely to pick up BHX from either knock or shannon is ryanair - it says a lot about ryanairs new strategy that they haven't picked up any of the lost UK routes out of shannon - they obviously have better utilisation and more profitable opportunities in primary airports across Europe - this will be the challenge going forward for regional airports like knock and shannon - I can see ryanair picking up BHX from knock but it will be at the expense of the EMA service. There simply are no other carriers out there to service these routes from knock or shannon - Otherwise they would have been picked up ahead of the summer season
