About this route
Boston (BOS) to Dublin (DUB) is one of the busiest air routes in its market (Transatlantic). It links Boston Logan International Airport in United States with Dublin Airport in Ireland. The great-circle distance is about 2,594 nautical miles (2,986 statute miles), so expect roughly 6 hours in the air nonstop.
Every night we ask our fare provider for the cheapest one-way economy fare other travellers recently found on this route and record it, with the airline and the seller it was found with. A fare is flagged as a deal when it falls at least 30% below the route's 90-day typical price. Prices are a research starting point, not live availability — the booking links open the itinerary so you can confirm what's on sale right now.
Fares are approximate, from public sources, and can be stale — always verify before booking.
