Best time to book & cheapest months
Book 55 days before departure to save 17% on average, per Google Flights 2025 data. April 2026 is the cheapest month with average prices at $389, while August peaks at $599. Flavia’s March 2025 trip cost $289 because she booked 55 days out on a Tuesday. Avoid December holidays—prices jump 33% compared to April. Eurostat 2025 reports 43% of European travelers book within 3 weeks of departure, but this route requires earlier booking for value.
Watch out for these airline traps
Alaska Airlines charges $150 for the first 30kg checked bag on SEA-NRT flights, not included in the $329 base fare listed on their site. Flavia learned this the hard way when her $150 fee was added at check-in for a 2024 trip. Most sites omit this fee, making prices seem lower. Always check baggage policies under "Additional Fees" before booking.
