The Washington–San Diego route
Washington to San Diego is a coast-to-coast domestic pairing: about 2,248 miles between IAD and SAN. Nonstop IAD–SAN is often on the schedule, about 5 hours airborne over 2,248 miles. Red-eyes and Saturday-night stays change the total more than the map distance.
For IAD–SAN we show about $119 on the low end and around $215 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 IAD to SAN 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 IAD–SAN
Great-circle distance IAD–SAN is about 2,248 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.
San Diego is about 3 hours behind Washington on standard time (America/New_York vs America/Los_Angeles). Arrival clocks on SAN are local. That matters more on this pair than on a same-zone hop.
When IAD–SAN 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 Washington to San Diego
Both ends are in the United States: Washington Dulles International (IAD) to San Diego International (SAN). 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 Washington, also compare DCA (Washington), BWI (Baltimore). SAN is the arrival code we treat as primary for San Diego. 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.
