Delta Air Lines Flights from Minneapolis to Seattle

Delta Air Lines on this route

Minneapolis is a Delta Air Lines hub, so Delta Air Lines typically offers several daily departures on MSP–SEA, with nonstop service where demand supports it and connections through its other hubs otherwise. The nonstop flight time is about 3h 29m.

Fare classes available: Basic Economy, Main Cabin, Comfort+, First Class / Delta One. Delta removed change fees on Main Cabin and above for travel originating in the US, Canada, Europe, Africa, and the Caribbean. You pay only the fare difference, and if the new flight is cheaper the difference is returned as an eCredit.

Recorded lows on MSP–SEA start at $239 one-way. That figure comes from cached search data and moves with demand, so treat it as a benchmark for what a good price looks like rather than a guaranteed fare.

Delta Air Lines and United Airlines both operate hubs at one end of this route, so nonstop or single-connection service is usually available, along with American Airlines and Southwest Airlines. Our agents can book any of them and compare fare classes side by side.

1,395 miles is a serious flight, roughly 3h 29m nonstop, and it is the range where premium economy or a domestic first-class seat can be worth asking about, particularly on midweek departures when upgrade fares drop.

When to fly

From the Midwest, the expensive weeks cluster around Thanksgiving, Christmas, and spring break in March; May, early June, September, and October tend to price lowest.

Midweek travel almost always beats weekends on price here. If your dates are flexible by a day or two, tell the agent; shifting a Friday departure to Thursday or a Sunday return to Monday is the single most reliable way to cut the fare.

For domestic travel, booking three to eight weeks ahead usually captures the best price. Inside two weeks, fares climb; more than four months out, airlines have not yet released their cheapest inventory.
