Heads up, deal hunters! There's a sweet fare popping up to Luxembourg (LUX) for under $500 roundtrip. The Flight Deal spotted it, and it looks like you can snag it using ITA Matrix to find the dates and then book on the airline's website. Now, here's the catch: this is a basic economy fare. That means you might have to pay extra for checked bags, seat selection, and even carry-ons depending on the airline's rules. But hey, for that price, you can pack light and still have plenty of cash left over to explore Luxembourg's castles and charming towns. Why should you care? Luxembourg is a hidden gem in Europe – think fairytale vibes without the crazy crowds. And flying there doesn't usually come this cheap. So, if you're flexible with your travel dates and don't mind flying bare-bones, this could be your chance for an affordable European adventure! Go check it out now, before the deal disappears!
