Frankfurt Book Fair (Frankfurter Buchmesse) is a major October draw, dramatically increasing hotel and flight demand near Frankfurt am Main Airport (FRAN). Additionally, Rhine Valley and regional wine harvest festivals in towns like Rüdesheim and Koblenz peak in October, offering scenic day trips from Frankfurt. While Munich’s Oktoberfest typically runs into early October, it is a train journey from Frankfurt and can also impact airfares. If traveling from Denver (All Airports) (DENA), book flights and hotels well in advance for fair dates and weekend wine festivals. CTA: Secure your October flight and accommodation early to avoid sold-out conditions during these events.

Early October weekdays often have lower fares compared to last-minute weekend bookings. Book 6–10 weeks in advance for best October pricing; business-heavy dates may cause higher fares, so consider arriving a day earlier or later than event start/end dates.
