At about 4,760 miles from Seattle-Tacoma International Airport (SEA) to Tokyo's Narita International Airport (NRT), a nonstop runs roughly 10h05, give or take with the winds. Nonstop award space in the data comes from Alaska Airlines, Japan Airlines, and Delta. The Airbus A330-900neo and Boeing 787-9 both appear on those nonstop award segments. Most award options in the data connect. Nonstops are just about 3% of the total.

The cabin call comes first on Seattle–Tokyo; on a long-haul trip, the right program follows from it. The cheapest economy seat is a partner award on an Alaska Airlines nonstop, so the lowest price is also the quickest trip. Taxes on that seat are missing from the data; check the cash portion at checkout before committing. Stepping up costs about 1.6 times the economy points for premium economy and about double for business.

Qatar Airways Privilege Club is cheapest in economy at 25,750 points on an Alaska Airlines nonstop. Alaska Atmos Rewards wins premium economy at 40,000 points on a Japan Airlines nonstop. Avianca LifeMiles takes business class at 51,580 points. First class starts at 85,000 points through Air Canada Aeroplan on a connecting itinerary, often first on one leg only, so confirm the cabin on each flight.

The Seattle–Tokyo nonstop is contested on points, with carriers from oneworld (Alaska Airlines, Japan Airlines) and SkyTeam (Delta) all showing award space. That gives partner currencies from both alliances a way onto a nonstop. When nonstop space is gone, the cheaper connecting awards in the data route through Vancouver, Seoul, and Los Angeles. The business-class floor is a Star Alliance partner award: Avianca LifeMiles prices United Airlines seats on the long-haul leg.

Distance ~4,760 miles; nonstop flying time ~10h05 (estimate). Tokyo is 16 hours ahead of Seattle (17 while Seattle is on standard time). The data runs October 2026–August 2027, with calendar prices for 11 months. Across well-covered months, October–December 2026 are among the cheapest, at 25,750 points, while March, June, and July 2027 (30,500–34,700) run higher.

Landing in the Tokyo area, Haneda (HND) comes in only slightly higher at 27,125 points in economy against the 25,750-point floor, making it a sensible check when Narita awards dry up. Haneda has nonstop flights from Seattle in the data too. Related award routes at last check: Los Angeles to Tokyo from 27,500 points and Seattle to London from 9,000. Seattle itineraries can also depart from Everett's Paine Field (PAE), so check the code before moving points.
