If you're craving a cheap, short escape, this one is for you. We've found a nonstop return flight from Barcelona to Luxembourg with Ryanair for €41. Against the €120 reference fare we've seen for this route, that's a saving of close to 66%.
The dates we found are an outbound flight on 13 November 2026 and a return on 14 November. It's aweekend trip that's easy to pull off, and Luxembourg Airport is well connected to the city.
Our advice: if the dates work for you, don't wait. Airline prices change constantly, and this one could rise within hours. Click through, check the fare is still the same, and book as soon as you can.
Once you're there, it's worth wandering through the Grund district along the Alzette River, then climbing up to the upper town for views from the Adolphe Bridge. You can also visit the Bock Casemates, an old fortress carved into the rock and one of the country's more curious corners.
If you have time left over, a trip to Vianden, with its medieval castle overlooking the valley, makes a great day out to round off the weekend.
