Cheap flights from Dublin to Luxembourg

The expensive stretch comes first: fares from Dublin climb over the summer holidays and again around Christmas, when Luxembourg's December market season keeps demand high. Things ease as autumn settles in, and September is the low point of this route's pricing, with the fare calendar here running from September to July. Midweek departures usually undercut Friday and Sunday flights, and the days around Luxembourg's national day in June bring a local bump. Once your dates are fixed, book at that point rather than gambling on a late price drop.

Ryanair is the clear low-cost name in the mix, and the rest lean full-service: Scandinavian Airlines, British Airways with its regional arm BA CityFlyer, KLM Royal Dutch Airlines with KLM Cityhopper, Lufthansa, Helvetic Airways and Luxair, Luxembourg's own flag carrier, with Air Baltic somewhere between the two models. A direct service runs alongside one-stop tickets through the network carriers' hubs, so the fare range here is wide. What is included differs sharply: the low-cost fare covers a seat and at most a small cabin bag, while full-service tickets typically bundle a proper cabin bag and rebooking help if a connection goes wrong.

Getting into town is the painless part of this trip: Luxembourg Airport sits close to the capital, so the transfer feels like a city bus commute rather than an airport trek. Public buses pull away from right outside arrivals and run into the centre and the main station quarter, while taxis wait by the exit and cover the same ground in a matter of minutes. The terminal is compact, so after a nonstop arrival you are normally landside quickly. If your plans stretch beyond the capital, sort onward rail and bus connections from the city centre rather than at the airport, because the country is small and its network centres on the capital.

Country facts: Wikidata

• Price bags into the total before you pick a fare, because the low-cost ticket on this route covers little more than a seat.
• Dublin and Luxembourg each have a single airport, so the real choice is between the nonstop service and one-stop itineraries through a network carrier.
• If your ticket involves a change, book it as one reservation so the airline has to rebook you when a leg runs late.
• Sort out your travel documents for Luxembourg before paying; both countries are in the EU, but entry rules depend on your nationality.
• Run your dates past the fare calendar, since September sits at the low end and the weeks around Christmas sit high.
