Seattle on points

Seattle-Tacoma International Airport sits at a peculiar intersection in the points-and-miles world. It is Alaska Airlines' home base, which means Mileage Plan awards price differently here than at almost any other US gateway. Layered on top of that, Delta operates a secondary Pacific hub out of SEA, ANA runs widebody service to Tokyo Narita (SEA-NRT), and Korean Air connects directly to Seoul Incheon (SEA-ICN). That combination of a dominant domestic carrier, a OneWorld-adjacent independent, and two SkyTeam-affiliated international operators gives SEA a partner density that most West Coast cities outside Los Angeles simply cannot match.

The headline sweet spot from SEA is Alaska Mileage Plan's Hawaii saver at 25,000 miles round-trip in economy on Alaska metal, one of the few remaining fixed-price domestic international awards in any major program. On the long-haul side, Mileage Plan prices Cathay Pacific business class to Asia at 50,000 miles one-way at the saver level, JAL business to Tokyo at 60,000 miles one-way, and Qantas business to Australia at 55,000 miles one-way. None of those partner awards are bookable out of every US gateway, but SEA's Alaska focus and the presence of ANA and Korean widebodies make the routing logic cleaner. If you find confirmed saver space on the ANA SEA-NRT segment, ANA Mileage Club prices that corridor at 88,000 miles round-trip in business under its legacy zone chart, still a competitive rate relative to our 1.5¢ conservative valuation for ANA miles.

Alliance strategy at SEA rewards a split approach rather than a single-alliance commitment. OneWorld-affiliated carriers (Alaska, Cathay, JAL, Qantas) give the broadest partner redemption options via Mileage Plan, and Alaska's outsized partner chart is the single strongest reason to accumulate Mileage Plan miles for SEA departures. SkyTeam presence via Delta and Korean opens a secondary lane: Korean SkyPass prices business class on Korean Air's SEA-ICN service, and Delta SkyMiles covers the same route on Delta metal, though our 1.1¢ SkyMiles valuation makes SkyPass the sharply more efficient vehicle when partner space is confirmed. Star Alliance has meaningful representation through ANA's Narita service, making programs like United MileagePlus (valued at 1.5¢ on rewardztravel.com) and ANA Mileage Club worth holding alongside your Mileage Plan balance.

Positioning into SEA from a smaller home airport is worth modeling when your local airport lacks nonstop international widebody service or when a specific partner award is only releasable on Seattle-originating itineraries. A short Alaska or Delta positioning flight from, say, Portland, Spokane, or Boise can unlock a SEA-NRT or SEA-ICN saver award that simply does not exist as a direct option from those cities. The positioning leg costs relatively few miles on Alaska or can be purchased as a cheap cash ticket, and the math often still beats a connecting itinerary on a program that reprices mid-itinerary. That said, positioning is only worth the friction if you have confirmed saver inventory on the long-haul segment before you book the feeder flight; saver business and first class seats on ANA, Korean, Cathay, and JAL out of SEA are capacity-controlled and frequently sparse, particularly in the window inside 60 days.

Transferable-point currencies that reach Mileage Plan include Capital One (at a 1:1 ratio to Alaska miles), making a Capital One card a practical on-ramp for SEA-centric strategies. Chase Ultimate Rewards does not transfer to Alaska, so UR holders working SEA routes should route through United MileagePlus for Star Alliance options or through Hyatt's travel partnerships for non-airline redemptions. American Express Membership Rewards reaches ANA directly at a 1:1 ratio, a useful path if ANA saver business space on the SEA-NRT route is available and you want to avoid the Mileage Plan partner-booking process entirely. Always confirm award availability before moving points; transfers from any bank currency to any airline program are immediate but irreversible.

Find the saver space first, then transfer the miles and book the positioner.
