Starting in mid-September through the end of October you can fly nonstop from Seattle to Denver for $111 roundtrip on Delta Air Lines.

Travel is available on Tuesdays and Wednesdays, but other days of the week are open for just $15 more at $126 roundtrip.

Searching on Delta's website, I found seats departing SEA on Tuesday, October 2, and returning from DEN on Tuesday, October 9, 2018.

We have a lot of flight deals heading out of Seattle today, so make sure to have a look at our SEA departures page.
