On a domestic run like Boston–Seattle, award prices go head to head with cash fares. The cheapest economy seat connects once; skipping the connection means an economy nonstop on Delta at a higher price. Taxes and fees on the economy floor run about $6, below the route's typical economy taxes. Run the miles-or-cash math each time: a cheap fare usually beats spending points. The exception is first class: at about double economy (less than business), it's the cabin where an award is most worth checking against the cash fare.
Alaska Atmos Rewards wins economy at 12,500 points. United MileagePlus takes business class at 62,000 points. American AAdvantage is cheapest in first class at 25,000 points. Of the other four, Delta SkyMiles, Qatar Airways Privilege Club, and Qantas Frequent Flyer are worth a look too. The cheapest program changes twice across the cabins, so match the program to the seat before moving points.
On points, Boston–Seattle has nonstop seats from Delta (SkyTeam) and Alaska Airlines (oneworld), which puts partner programs from both alliances in play for a nonstop. The cheaper connecting awards in the data change planes in Dallas/Fort Worth, Chicago, and Washington.
The return, Seattle to Boston, has its own page, since award pricing can differ by direction. If the destination is open, Boston to Atlanta prices from 11,000 points at last check. Seattle awards can also land at Everett's Paine Field (PAE), so check the arrival code before transferring points.
