Hey awardtrail readers, ready for a European getaway that won't break the bank? We spotted some crazy good deals to Luxembourg, with flights dipping below $400 roundtrip from various US cities. You'll need to do a little digging using the Matrix Airfare Search by ITA Software (basically, a powerful flight search tool) to find these fares. Just punch in your dates and desired destination, and it'll unearth the lowest prices. Now, the catch: these are typically Basic Economy fares. That means you'll likely have to pay extra for things like checked bags and seat selection. But, if you're a light packer and don't mind where you sit, this is an incredible opportunity to explore a charming European country without emptying your wallet. Think fairytale castles, delicious pastries, and maybe even a side trip to nearby Belgium or France! Why should you care? Well, affordable flights are the key to unlocking more travel experiences. Luxembourg might not be at the top of everyone's bucket list, but at this price, it's worth considering. Plus, it's a great base for exploring other parts of Europe. Just remember to factor in those potential extra fees for luggage and seating when budgeting for your trip!
