To find cheap flights from Detroit Metropolitan Wayne County Airport (DTW) to EuroAirport Basel Mulhouse Freiburg (BSL) in October, search flexible-date calendars, compare multi-airline itineraries, and consider red-eye or midweek departures. Use nearby hubs like Zurich (ZRH) or Geneva (GVA)—combined with a short rail transfer—to lower costs. Leverage fare alerts, book 6–10 weeks ahead, and consider longer layovers that often reduce prices. For October, shoulder-season demand can produce bargains, especially if you avoid weekend peaks during Basel events.
Tips
- Set price alerts on multiple search engines and check airline flash sales.
- Compare flying into Zurich (ZRH) or Geneva (GVA) and taking a train to Basel for cheaper fares.
- Book flights on Tuesdays–Wednesdays for potential lower fares, and be flexible with travel dates in October.
- Use alliance partners to combine the cheapest legs while maintaining baggage protections.
