Nonstops are just about 8% of the total.
On a long-haul trip like London–Seattle, pick the cabin before the program. Saving points means connecting: the economy floor connects once, and an economy nonstop on Alaska Airlines costs more. The cheapest economy seat adds about $394 in taxes and fees, in line with the route's typical economy taxes. Stepping up costs about 2.7 times the economy points for premium economy and about 8 times for business, though the cheapest business award carries heavy fees.
Virgin Atlantic Flying Club wins economy at 15,000 points. American AAdvantage takes premium economy at 40,000 points. Qantas Frequent Flyer is cheapest in business class at 119,400 points. First class starts at 150,000 points through Alaska Atmos Rewards on a connecting itinerary, often first on one leg only, so confirm the cabin on each flight. Also in the mix: Aeromexico Rewards, Delta SkyMiles, and Qatar Airways Privilege Club.
The London–Seattle nonstop is contested on points: Alaska Airlines (oneworld) and Delta (SkyTeam) both show award space. That gives partner currencies from both alliances a way onto a nonstop. Connecting awards near the price floor run through Los Angeles and Paris. Virgin Atlantic Flying Club sets the economy floor as a SkyTeam partner, selling Air France seats at its own rates.
The return, Seattle to London, has its own page, since award pricing can differ by direction. Flexible on where you land? London to Miami starts from 7,500 points at last check. Check the arrival code before transferring points, since Seattle awards can also land at Everett's Paine Field (PAE).
