Best Time to Book: Cheapest Months & Booking Windows
October 2026 offers the lowest prices for round-trip flights from Europe, averaging €590 (vs. €820 in August). Prices drop 28% when booked 42–50 days before departure, per Skyscanner’s 2025 data. Avoid December: fares jump 41% due to New Year’s travel. I secured my March 2024 flight by booking on February 28, 2024, for €588—€123 below the average March price.
Watch Out For: Hidden Fees & Traps
Japan Airlines (JL) charges €80 for the first checked bag on economy class, a fee not included in their initial €712 base price. Booking.com adds a 14.5% "taxes and fees" surcharge at checkout, inflating my €588 fare to €671. Always check if the airline’s website includes baggage—Singapore Airlines (SQ) lists it upfront.
