The Seattle–Detroit route
Seattle to Detroit is a coast-to-coast domestic pairing: about 1,922 miles between SEA and DTW. Nonstop SEA–DTW is often on the schedule, about 4.5 hours airborne over 1,922 miles. Red-eyes and Saturday-night stays change the total more than the map distance.
For SEA–DTW we show about $149 on the low end and around $240 as a more typical one-way economy total, USD, last reviewed August 2026. A $149 one-way is a sale-shaped guide, not a fare you can screenshot and demand. Taxes, bags, and seats change what you pay on the seller site.

Distance and time SEA–DTW
Great-circle distance SEA–DTW is about 1,922 miles. Block time on a nonstop is typically near 4.5 hours; wind, routing, and which runway you use still move the clock. Connections on the same city pair add layover time on top of that flying.
Detroit is about 3 hours ahead of Seattle on standard time (America/Los_Angeles vs America/New_York). Arrival clocks on DTW are local. That matters more on this pair than on a same-zone hop.
When SEA–DTW has a nonstop, that is usually the cleanest product. One-stop options still appear — they are worth opening only if the USD total is materially lower after you count the extra ground time.
Airports for Seattle to Detroit
Both ends are in the United States: Seattle-Tacoma International (SEA) to Detroit Metropolitan Wayne County (DTW). This is not an international itinerary, so the usual domestic bag and ID rules apply at the seller. Alternate metro airports can still beat this pair on price.
SEA is the only origin code we list in this metro. DTW is the arrival code we treat as primary for Detroit. A cheaper nearby airport only wins if the transfer still fits your plan. Search with “include nearby airports” when you want those codes in one results list.
