Route

Seattle–London Flights

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.

Strategy

Best Ways to Book With Points & Miles

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.

Best Points & Miles Programs

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.

Premium economy also prices as a partner award, with one airline's miles buying another airline's seat.

Airlines & Routing Options

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.
