Choosing between direct and connecting flights from Boston Logan International Airport (BOS) to Barcelona–El Prat Airport (BCN) in September depends on priorities. Direct nonstops (when available) minimize travel time—typically 7.5–8.5 hours—and reduce risks tied to missed connections, making them ideal for short trips or minimal-stress travel. Connecting flights through hubs like Madrid (MAD), London (LHR), Dublin (DUB), or Reykjavik (KEF) often lower fares and increase scheduling flexibility but add connection time and potential delays. If price is primary, one-stop routings can offer significant savings; if convenience and shorter total trip time matter most, opt for any available nonstop. Always allow adequate connection time and verify minimum connection times for international-to-international layovers in September schedules.
