The Washington–Dublin route
Washington to Dublin is a transatlantic search from a US airport. You leave Washington Dulles International (IAD) and land at Dublin Airport (DUB) in Ireland, about 3,395 miles away. Nonstop IAD–DUB is often on the schedule, about 7 hours airborne over 3,395 miles.
For IAD–DUB we show about $269 on the low end and around $470 as a more typical one-way economy total, USD, last reviewed August 2026. Long-haul sale banners expire; a $269 one-way is a planning floor, not a coupon. Taxes, bags, and seats change what you pay on the seller site.
Search IAD to DUB on Azurovia, compare airline-direct and travel-site totals on the same flights, then finish with the seller. We do not ticket. Keep their confirmation for changes.
Distance and time IAD–DUB
Great-circle distance IAD–DUB is about 3,395 miles. Block time on a nonstop is typically near 7 hours; wind, routing, and which runway you use still move the clock. Connections on the same city pair add layover time on top of that flying.
Dublin is about 5 hours ahead of Washington on standard time (America/New_York vs Europe/Dublin). Arrival clocks on DUB are local. That matters more on this pair than on a same-zone hop.
When IAD–DUB has a nonstop, that is usually the cleanest product. One-stop options still appear — they are worth opening only if the USD total is materially lower after you count the extra ground time.
Airports for Washington to Dublin
You depart Washington Dulles International in Washington, United States, and arrive at Dublin Airport in Dublin, Ireland. IAD is the origin code we use on this guide; DUB is the arrival code. If you need a visa or an ESTA, that is between you and the destination government — Azurovia does not ticket and does not process immigration.
Near Washington, also compare DCA (Washington), BWI (Baltimore). DUB is the arrival code we treat as primary for Dublin. A cheaper nearby airport only wins if the transfer still fits your plan. Search with “include nearby airports” when you want those codes in one results list.
