Delta Offers $12 Comfort Upgrades on Seattle Flights

Delta kicked off a four-day fall sale on Monday, discounting fares across its domestic network to and from Seattle while throwing in a novelty perk: Delta Comfort upgrades for as little as $12 roundtrip. The airline said the promotion, which opened at 8 p.m. EDT (5 p.m. PDT) on Oct. 5, covers nearly 50 nonstop domestic destinations out of Seattle-Tacoma International Airport and runs through Oct. 8.

Travel booked under the promotion is valid from late October through March 10, 2027, though Delta cautioned that all fares carry blackout dates, availability limits and standard restrictions. The carrier is pitching the sale toward winter getaways, family visits and long-weekend trips, with added savings highlighted on routes between Seattle and Hawaii.

Hawaii routes and the $12 Comfort tie-in

Four Hawaii destinations are called out specifically: Honolulu, Maui, Kona and Lihue, all served nonstop from Seattle. Delta is steering shoppers to a dedicated page, delta.com/seattledeals, for the current roster of discounted Seattle itineraries.

The more unusual piece of the promotion is the Delta Comfort upgrade priced at $12 each way on eligible roundtrip Seattle flights — a number Delta tied directly to the Seattle Seahawks' "12s" fan base. Delta, which brands itself the official airline of the Seahawks, framed the discount as a nod to the team defending its championship title this season. The $12 price reflects a $6 upsell each way compared with Delta's Main Classic fare on the same flight, and applies only to new revenue bookings on Delta-marketed and -operated nonstop Seattle routes within the promotional window of Oct. 5 to Oct. 8. A roundtrip purchase is required to qualify.

Delta Comfort seating includes extra legroom, early Zone 3 boarding, dedicated overhead bin space and complimentary beer, wine and spirits for passengers 21 and older on eligible flights. Delta is marketing the upgrade as available even on fares already discounted through the fall sale, effectively stacking two promotions for Seattle-based flyers.

A separate window for Alaska SkyMiles members

Delta carved out a second, slightly longer promotional period for SkyMiles members based in Alaska, running from Oct. 6 through Oct. 20. That offer targets warm-weather escapes, with Delta pointing Alaskan travelers toward discounted fares to Florida beaches, Hawaii's islands and Southwest destinations as alternatives to winter weather at home.

Delta has not said how many seats are allocated to the discounted fares or whether the Comfort upgrade promotion will return for future Seahawks home games. Travelers interested in either deal should book before the respective windows close, since Delta's offer terms emphasize that both fares and upgrade availability are limited and subject to change.
