The Boston to Dublin route covers roughly 2,990 miles and takes about 6h 10m nonstop. 3 airlines compete on it — Aer Lingus, Delta Air Lines, JetBlue Airways — which keeps fares moving and makes it worth comparing carriers rather than defaulting to the one you usually fly.

Dublin is compact, walkable and unusually easy to reach from the United States, with more transatlantic service than a city its size would normally support.
Trinity College and the Book of Kells, the Guinness Storehouse and a pub culture that is genuinely about conversation rather than spectacle define the city. The Wicklow Mountains and the coastal villages start 30 minutes out.
