Cheap flights from Dublin to Frankfurt

October is the cheapest month on this route, so if your dates are flexible, start there. Fares climb through the summer school holidays and again around Christmas and Easter, when everyone wants to travel at once. Spring and late autumn tend to sit in the middle. Midweek departures, especially Tuesday and Wednesday, are usually gentler on the wallet than Friday evenings or Sunday nights. Book a few weeks ahead for the cheap months, and earlier still if you are tied to a holiday week. The price calendar on this page shows what each month costs, so you can see the gap for yourself.

Aer Lingus, Lufthansa, KLM Royal Dutch Airlines, Swiss, Air France, Scandinavian Airlines and Lufthansa City Airlines are the full-service names here. Iberia Express, HiSky and Air Baltic sit at the low-cost end, where the fare usually buys a seat and a small cabin bag and not much else. Non-stop seats exist on the route; the rest of the list sells you a connection through a hub, which can still be the cheaper way to go. Full-service tickets usually include a cabin bag and a drink, though the allowance depends on the fare you choose. Compare the total rather than the headline: a low-cost fare plus a checked bag can come close to a flexible full-service ticket.

Frankfurt shows two airports in the results, and they are not interchangeable. Frankfurt International sits close to the city, with frequent trains into the centre and a short ride to the main station. Hahn Airport is a long way out in the countryside and you reach it mainly by coach. Check which one your ticket uses before you book, because the transfer on arrival is very different. From Frankfurt International, follow the signs for the S-Bahn or regional trains if you are heading downtown; the train usually beats a taxi in traffic. From Hahn, the coach is the practical option, and it runs less often late in the evening, so allow extra time if you land late.

Country facts: Wikidata

• Check which Frankfurt airport your ticket uses, because Hahn and Frankfurt International are far apart.
• What baggage is included, especially on the low-cost fares where a checked bag costs extra.
• If your trip is built from separate tickets, leave a generous gap in case the first leg runs late.
• Bring a valid passport or national identity card, since Ireland and Germany are both in the European Union.
• Compare October against the dates you can actually travel, because the cheapest month only helps if it fits.
• Book early for summer and Christmas travel, when the cheap seats on this route go first.
