For ORD–SEA we show about $119 on the low end and around $200 as a more typical one-way economy total, USD, last reviewed August 2026. A $119 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 ORD–SEA
Great-circle distance ORD–SEA is about 1,716 miles. Block time on a nonstop is typically near 4 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.
Seattle is about 2 hours behind Chicago on standard time (America/Chicago vs America/Los_Angeles). Arrival clocks on SEA are local. That matters more on this pair than on a same-zone hop.
When ORD–SEA 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 Chicago to Seattle
Both ends are in the United States: O'Hare International (ORD) to Seattle-Tacoma International (SEA). 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.
Near Chicago, also compare MDW (Chicago). SEA is the arrival code we treat as primary for Seattle. 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.
