For IAD–SJO we show about $189 on the low end and around $350 as a more typical one-way economy total, USD, last reviewed August 2026. A $189 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 IAD–SJO
The map distance is about 2,044 miles. Without a regular nonstop from IAD to SJO, plan on 4.5 hours of flying plus a connection. Filter results by total trip time, not only by the number of stops.
San Jose is about 1 hour behind Washington on standard time (America/New_York vs America/Costa_Rica). Arrival clocks on SJO are local. That matters more on this pair than on a same-zone hop.
Most Washington–San Jose journeys connect rather than fly nonstop from IAD. Timed one-stop itineraries often bank at Miami International (MIA), George Bush Intercontinental (IAH), Hartsfield-Jackson Atlanta International (ATL). That is a pattern, not a promise for your dates. On results, sort by fastest if you care about layover pain, or cheapest if you do not.
