Cheap flights from Belfast to Frankfurt

June is when fares on this route tend to sit lowest, and the price calendar shows it clearly against the months around it. Spring and early autumn are the pleasant compromise: milder weather, thinner crowds and fares that have not yet climbed towards the summer peak. Weekday departures usually cost less than Friday and Sunday flights, which is worth remembering if your trip is flexible. Frankfurt fills up around trade fairs and in the run-up to Christmas, when the market season pulls in visitors, and Belfast empties out around school breaks in the opposite direction. Book early for June, and earlier still if your dates land on a holiday weekend.

Nothing on this route is non-stop, so the airline you pick decides where you change planes rather than whether you do. Easyjet is the low-cost name in the mix and keeps fares lean by charging separately for things like checked bags. KLM Royal Dutch Airlines routes many Belfast passengers through its Amsterdam hub, while Lufthansa does the same through Frankfurt itself. Aer Lingus connects over Dublin, and British Airways with its BA CityFlyer arm connects over London. Swiss adds another option through Zurich. On the full-service carriers, what is included depends on the fare family you choose, so compare the total with a bag added, not just the headline fare.

Frankfurt International is the airport most connections land at, and it sits right by the city with its own station, so trains into the centre are the simplest way in. Hahn Airport is a different story: it lies well outside Frankfurt, in the Hunsrück countryside, and you reach the city by coach rather than by train, which adds a long road transfer to your journey. If your itinerary shows Hahn, treat it as a separate arrival and plan the coach leg before you fly. At Frankfurt International, follow the signs for the S-Bahn and regional trains once you clear arrivals, and keep your onward ticket handy.

Country facts: Wikidata

• Every itinerary connects, so check whether both legs sit on one ticket before you book, because separate tickets mean you carry the risk of a missed connection.
• All Belfast departures leave from George Best City, so there is no airport choice at this end, but confirm which Frankfurt airport your connection uses.
• On Easyjet, add a checked bag to the fare and compare the total against the full-service options.
• Check the entry rules for Germany for your nationality and carry the right travel document.
• Compare June fares with the shoulder months on the price calendar before you commit.
• If your connection is in London or Amsterdam, check the layover time before you book.
