Well the engine needs a tune up then, because it's not running efficiently. And I'm not talking about only the Airport departure lounges.
Just on the "economic engine" while it about 39.5% of GDP (147bn of 373bn, 2020 CSO figures preliminary) it does seem to suck in a lot of economic activity that would be well catered for in other regions including air travel.
I appreciate that most Multinationals want to locate in Dublin for many reasons but if Dublin is bursting at the seems perhaps its time to utilise other regions.
It's a small country with excellent connectivity via motorways. Slightly off topic
