Roughly 4,790 miles separate Seattle-Tacoma International Airport (SEA) and London Heathrow Airport (LHR), so a nonstop spends about 10h05 in the air, a little more or less depending on winds and direction. The nonstop award space in the data is split across Virgin Atlantic, Delta, Alaska Airlines, and British Airways. Aircraft logged on those nonstops include the Airbus A330-900neo, Airbus A330-200, and Boeing 787-9. Nonstops make up only about 3% of the award options in the data; the rest connect.
The cabin call comes first on Seattle–London; on a long-haul trip, the right program follows from it. The cheapest economy seat is a Virgin Atlantic nonstop booked through the airline's own program, so saving points costs no extra time. Its $164 in taxes and fees is the catch, well above the route's typical economy taxes; more points and less cash can come out ahead. Stepping up costs about 3.9 times the economy points for premium economy and about 6 times for business.
Virgin Atlantic Flying Club wins economy at 9,000 points on a Virgin Atlantic nonstop. Alaska Atmos Rewards takes premium economy at 35,000 points and business class at 55,000. Its 55,000-point first-class fare connects; treat it as mixed-cabin until each segment's cabin checks out. The other 10 programs include Air Canada Aeroplan, American AAdvantage, and Air France-KLM Flying Blue. Premium economy also prices as a partner award, with one airline's miles buying another airline's seat.
On points, Seattle–London has nonstop seats from Virgin Atlantic (SkyTeam), Delta (SkyTeam), Alaska Airlines (oneworld), and British Airways (oneworld), which puts partner programs from both alliances in play for a nonstop. Connecting awards near the price floor run through Chicago, Frankfurt, and Paris; they're the fallback when the nonstop is full. Partner pricing sets the business-class floor: Alaska Atmos Rewards books British Airways as a oneworld partner, and no program prices British Airways lower in that cabin at last check.
Check airport codes before transferring points: Seattle awards can also leave from Everett's Paine Field (PAE), and London awards can also land at Gatwick (LGW). Also tracked into London: Boston to London, from 6,000 points at last check. Seattle has no cheaper long-haul route tracked; Paris is next, from 9,500 points.
