I used to hope Southwest would expand internationally beyond Mexico and the Caribbean, but unfortunately, they don’t fly to Europe. I learned this the hard way while planning my first solo trip to Italy. I thought I could hack together a cheap itinerary using Southwest points, but no luck.

They confirmed that Southwest doesn’t operate long-haul flights, so I ended up mixing another carrier with a separate Southwest domestic leg. It wasn’t seamless, but it worked. If you’re trying to stretch Southwest points, the best approach is usually flying them to a gateway city like JFK or Boston and then hopping a separate international carrier.
