Airports of Ireland
Ireland is a small island with a surprisingly functional airport network — six commercial airports spread across the country, though "spread" might be generous. The reality is that Dublin Airport (DUB) pulls most of the weight, connecting Ireland to over 200 destinations worldwide while the rest of the country makes do with regional options. It's a hub-dominant system, which makes sense for a nation this size. The west and south have their own airports, but they're operating on a different scale entirely — useful, not dominant.
The shape of Ireland's aviation network
What strikes me about Ireland's airport setup is how honestly it reflects the country's geography and population. DUB isn't just the biggest airport — it's in a different league entirely, with 201 non-stop routes making it one of the better-connected hubs in Europe for its region. That's the kind of reach that punches well above a country Ireland's size. Cork (ORK) does solid work in the south with 49 destinations, and Shannon (SNN) holds its own in the west with 39 routes — handy if you're heading into Clare or Galway without wanting to cross the whole island. Even Knock, which I'd expect to be a quiet regional afterthought, runs 18 routes. Ireland hasn't let its smaller airports become completely irrelevant, which I respect.

Tips for using Ireland's airports
Flying into DUB gives you the most options by a long shot, and it's the practical choice for most trips. But if you're heading to the west of Ireland, seriously consider SNN — skipping Dublin means skipping a long drive across country. Cork is worth checking for southern trips, especially since transatlantic and European routes have grown there. The one minor airfield in the network serves very few destinations, so treat it as a niche option rather than a real alternative. Ground transport between airports isn't quick on an island with rural roads, so pick your entry point before you book.
