Cheap flights from Dublin to Houston

Aim for October first — fares on this pairing bottom out then, and the covered price calendar stretches from September to June. Around that low, autumn and late spring stay moderate, while Thanksgiving week in the United States, the Christmas and New Year break and the spring break weeks in March push demand up. July and August fall outside the covered months, and Houston's heat peaks then, so treat deep summer as peak season and plan your days around the weather. Midweek departures usually undercut Friday-to-Sunday ones, and holiday-adjacent dates reward early booking far more than flexible autumn ones.

What a fare includes is where the real differences sit: every itinerary is a connection, and the operating airline's rules tend to follow you the whole way. WestJet and JetBlue sit on the low-cost side, pricing the seat lean and selling checked bags, seat choice and meals as extras. Aer Lingus blends a lean base fare with full long-haul service, while British Airways, Lufthansa, Finnair, Iberia, TAP Portugal, Turkish Airlines and American Airlines run full-service networks, with a checked bag and meals usually included on the ocean leg. Fares often stitch two carriers together, so check which airline operates each leg and weigh journey time and extras against the headline fare.

Which airport you land at comes first: George Bush Intercontinental sits to the north of the city, while Hobby is southeast and closer in, and the two lie far enough apart that a mix-up costs you a long cross-town drive. Houston is built for cars — distances are wide and public transport in from either airport is thin — so most arrivals take a rental car, a taxi or a rideshare, all straightforward to arrange at both terminals. Where you clear United States immigration depends on the routing, so check it before you fly and leave slack in your first hours for the formalities.

Country facts: Wikidata

• Check which Houston airport your fare uses, Hobby or George Bush Intercontinental, because the two sit at opposite ends of the city.
• On the leaner carriers such as WestJet and JetBlue, price a checked bag and a seat into the total before you compare fares.
• Have your passport and, if you travel visa-free, an approved electronic travel authorisation for the United States sorted before departure.
• If the connection is on two separate tickets, leave a long buffer, because the second airline owes you nothing when the first runs late.
• Weigh October dates against the holiday peaks on the calendar before you fix your travel window.
