Since there are no direct flights between Sioux Falls Regional Airport (FSD) and Florence Airport, Peretola (FLR), travelers must book connecting itineraries. Connecting flights offer more carrier options and potentially lower fares, but increase risk of missed connections during December due to weather. Favor major U.S. hubs (MSP, ORD, ATL) for reliable services and pick European hubs with frequent onward service (FRA, CDG, AMS). When booking in December, choose longer layovers or protected single-ticket itineraries to reduce stress from winter delays. CTA: Compare connecting routes and choose connections with ample buffer time for December travel.
