Delta has launched a new fall sale with discounted fares and some seriously cheap Delta Comfort upgrades for travelers flying to or from Seattle and Alaska.

There are deals on dozens of routes, including flights to Hawaii, but you’ll need to act quickly: The sale ends October 8.

Here’s what you need to know.

Delta’s Seattle and Alaska Sale Offers Comfort Upgrades From $1

Delta‘s latest sale actually includes 2 separate offers: one focused on flights to and from Seattle and another for travelers flying to or from Alaska.

Both are available for bookings through October 8, 2026, but the discounts and Delta Comfort upgrade offers vary by destination.

Save up to 40% on Delta Flights From Seattle

The Atlanta-based carrier is discounting fares on nearly 50 domestic nonstop routes to and from Seattle (SEA), with savings of up to 30% during the sale.

Flights between Seattle and Hawaii get an even bigger discount of up to 40%. Delta currently flies nonstop from Seattle to 4 Hawaiian airports:

Honolulu (HNL)
Maui (OGG)
Kona (KOA)
Lihue (LIH)

There’s also a Delta Comfort deal starting at just $12 round-trip (or $6 each way) on eligible nonstop flights from Seattle. And if you’re wondering about the oddly specific $12 rate, it’s a nod to Seattle Seahawks fans, better known as the “12s.”

Delta Comfort comes with extra legroom, Zone 3 boarding, dedicated overhead bin space, and complimentary beer, wine, and spirits for travelers 21 and older on eligible flights.

Get Delta Comfort Upgrades for $1 on Alaska Flights

For the first time, Delta is offering Delta Comfort upgrades for just $1 each way on eligible flights to and from Anchorage (ANC) and Fairbanks (FAI). The $1 upgrade is available on eligible Delta-operated nonstop flights, as well as certain 1-stop itineraries between Alaska and 4 Florida airports:

Fort Lauderdale (FLL)
Miami (MIA)
Orlando (MCO)
Tampa (TPA)

Delta is also offering up to 15% off select nonstop flights between Seattle and Anchorage (ANC) or Fairbanks (FAI).

There are a few important restrictions. These offers are available only on new cash bookings made by October 8, require a round-trip purchase, and are subject to availability, blackout dates, and other restrictions.

Hot Tip:

If you’re booking an eligible Alaska itinerary from Florida, paying an extra $2 round-trip for Delta Comfort is a no-brainer.

Final Thoughts

There are some solid savings here if Seattle or Alaska is in your travel plans, but the $1 Delta Comfort upgrades are easily the highlight. Just remember that you only have through October 8 to book, and availability could disappear before then.
