Distance and time SEA–SJU
The map distance is about 3,726 miles. Without a regular nonstop from SEA to SJU, plan on 8 hours of flying plus a connection. Filter results by total trip time, not only by the number of stops.
San Juan is about 4 hours ahead of Seattle on standard time (America/Los_Angeles vs America/Puerto_Rico). Arrival clocks on SJU are local. That matters more on this pair than on a same-zone hop.
Most Seattle–San Juan journeys connect rather than fly nonstop from SEA. Timed one-stop itineraries often bank at Miami International (MIA), Fort Lauderdale-Hollywood International (FLL), 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.
