How this list is made

Every total comes from the same cost model as our 32 head-to-head matchups: round-trip economy flights for 2 from SEA, 7 nights in a mid-range room, and daily food, local transport and activities (plus lift tickets on ski trips). Only destinations whose SEA fare range comes from fares Aviasales travelers found recently (Travelpayouts Data API, departures about 1–4 months out, updated within the last 60 days) are ranked; the list and PDF regenerate automatically whenever those fares change.
