Denver–Seattle Flights
This route runs from Denver (DEN) to Seattle-Tacoma International Airport (SEA). Nonstop award space in the data comes from Delta, Alaska Airlines, and United Airlines.

Best Ways to Book With Points & Miles
Booking Denver–Seattle with points starts with the cabin, then the program. The cheapest economy seat is a Delta nonstop booked through the airline's own program, so saving points costs no extra time. Taxes and fees on that seat run about $6, in line with the route's typical economy taxes. Business runs about 4 times the economy price. Flexible bank points can reach Delta SkyMiles; confirm the space first, since transfers can't be undone.
Best Points & Miles Programs
Delta SkyMiles is cheapest in economy at 7,100 points on a Delta nonstop. Qantas Frequent Flyer wins business class at 31,500 points on an Alaska Airlines nonstop. Alaska Atmos Rewards lists first class from 20,000 points, but the fare connects, which usually means first on one leg only; read every segment. Of the other four, American AAdvantage, Air France-KLM Flying Blue, and United MileagePlus are worth a look too.
Airlines & Routing Options
Denver–Seattle draws nonstop award space from three alliances: Delta (SkyTeam), Alaska Airlines (oneworld), and United Airlines (Star Alliance). Partner programs in all three alliances can each book a nonstop. When nonstop space is gone, the cheaper connecting awards in the data route through Dallas/Fort Worth. The business-class floor is a oneworld partner award: Qantas Frequent Flyer prices the Alaska Airlines nonstop. Only four airlines show award space here, but seven programs sell their seats, so the program matters more than the carrier.
Alternative Airports & Routes
The return, Seattle to Denver, has its own page, since award pricing can differ by direction. For another option from Denver, Cancun prices from 7,400 points at last check. Seattle awards can also arrive at Everett's Paine Field (PAE). It's worth confirming the arrival code before moving points.
Booking tips
- 1Search flexible dates first, since saver award seats can appear on scattered days.
- 2Compare partner programs before transferring points, since the same seat can price very differently.
- 3Check both direct and connecting options when direct award seats are limited.
- 4Book early for peak travel periods, when saver space disappears fastest.
- 5Recheck availability often, since airlines may release more award seats closer to departure.
