The Houston–Dublin route
Houston to Dublin is a transatlantic search from a US airport. You leave George Bush Intercontinental (IAH) and land at Dublin Airport (DUB) in Ireland, about 4,548 miles away. This city pair is usually a connecting trip: about 4,548 miles of flying, with the shortest timed itineraries near 9.5 hours plus a layover.
For IAH–DUB we show about $389 on the low end and around $680 as a more typical one-way economy total, USD, last reviewed August 2026. Long-haul sale banners expire; a $389 one-way is a planning floor, not a coupon. Taxes, bags, and seats change what you pay on the seller site.
Search IAH 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 IAH–DUB
Houston and Dublin sit about 4,548 miles apart. If a nonstop is missing from IAH, timed itineraries near 9.5 hours of flying usually mean one long-haul plus a shorter feeder — not two equal hops.
Dublin is about 6 hours ahead of Houston on standard time (America/Chicago vs Europe/Dublin). Arrival clocks on DUB are local. That matters more on this pair than on a same-zone hop.
Most Houston–Dublin journeys connect rather than fly nonstop from IAH. Timed one-stop itineraries often bank at John F. Kennedy International (JFK), Newark Liberty International (EWR), O'Hare International (ORD). That is a pattern, not a promise for your dates. On results, sort by fastest if you care about layover pain, or cheapest if you do not.
Airports for Houston to Dublin
You depart George Bush Intercontinental in Houston, United States, and arrive at Dublin Airport in Dublin, Ireland. IAH 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.
IAH is the only origin code we list in this metro. 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.
