The Seattle–Baltimore route
Seattle to Baltimore is a coast-to-coast domestic pairing: about 2,329 miles between SEA and BWI. Nonstop SEA–BWI is often on the schedule, about 5 hours airborne over 2,329 miles. Red-eyes and Saturday-night stays change the total more than the map distance.
For SEA–BWI we show about $119 on the low end and around $205 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.
Search SEA to BWI on Azurovia, compare airline-direct and travel-site totals on the same flights, then finish with the seller. We do not ticket. Keep their confirmation for changes.
Distance and time SEA–BWI
Great-circle distance SEA–BWI is about 2,329 miles. Block time on a nonstop is typically near 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.
Baltimore is about 3 hours ahead of Seattle on standard time (America/Los_Angeles vs America/New_York). Arrival clocks on BWI are local. That matters more on this pair than on a same-zone hop.
When SEA–BWI 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 Baltimore
Both ends are in the United States: Seattle-Tacoma International (SEA) to Baltimore/Washington International (BWI). 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. On arrival, DCA (Washington), IAD (Washington) can price differently from BWI. 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.
