I understand what you are saying considering that, assuming these are gone, the only route operated from Munster to a UK airport outside London in a 737/A320 will be Cork's Liverpool service, which has itself been scaled back in recent years.
But that opens the question of what Knock is doing right. Despite a more limited catchment and not being near Ireland's big tourist draws around Kerry and Clare, it will still have three 737 operated UK regional services.
