Key Takeaways: Boston (BOS) to Dublin (DUB)
Non-stop flights between Boston Logan (BOS) and Dublin (DUB) on Aer Lingus or Delta average $780 during peak tourist months.

Why Direct Flights on This Corridor Carry a 38% Markup
Aer Lingus and the oneworld transatlantic alliance maintain an effective non-stop monopoly out of Boston due to deep historical Irish-American ties. Mid-Atlantic unbundling bypasses through-fare premiums.
