The Seattle–Madrid route
Seattle to Madrid is a transatlantic search from a US airport. You leave Seattle-Tacoma International (SEA) and land at Adolfo Suárez Madrid-Barajas (MAD) in Spain, about 5,297 miles away. This city pair is usually a connecting trip: about 5,297 miles of flying, with the shortest timed itineraries near 11 hours plus a layover.
For SEA–MAD we show about $399 on the low end and around $720 as a more typical one-way economy total, USD, last reviewed August 2026. Long-haul sale banners expire; a $399 one-way is a planning floor, not a coupon. Taxes, bags, and seats change what you pay on the seller site.
Search SEA to MAD on Azurovia, compare airline-direct and travel-site totals on the same flights, then finish with the seller. We do not ticket. Keep their confirmation for changes.
Distance and time SEA–MAD
Seattle and Madrid sit about 5,297 miles apart. If a nonstop is missing from SEA, timed itineraries near 11 hours of flying usually mean one long-haul plus a shorter feeder — not two equal hops.
Madrid is about 9 hours ahead of Seattle on standard time (America/Los_Angeles vs Europe/Madrid). Arrival clocks on MAD are local. That matters more on this pair than on a same-zone hop.
Most Seattle–Madrid journeys connect rather than fly nonstop from SEA. Timed one-stop itineraries often bank at John F. Kennedy International (JFK), Newark Liberty International (EWR), O'Hare International (ORD). That is a pattern, not a promise for your dates. On results, sort by fastest if you care about layover pain, or cheapest if you do not.
