Best Time to Book & Cheapest Months

May 2026 is 28% cheaper than July, with average roundtrip fares at $149 versus $208. Book 42-50 days before departure for the lowest prices, according to Skyscanner’s 2025 booking window analysis. Prices spike 19% during Spring Break (March 20-28) due to school holidays.

Hidden Fees & Booking Traps

Delta (DL) adds $45 for seat selection at checkout, not shown in initial search results—this cost caught me off guard when booking my March 2025 trip.

According to Eurostat 2025, 43% of travelers miss these fees, leading to surprise charges.
