Distance and time SAN–IAH
Great-circle distance SAN–IAH is about 1,301 miles. Block time on a nonstop is typically near 3 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.
Houston is about 2 hours ahead of San Diego on standard time (America/Los_Angeles vs America/Chicago). Arrival clocks on IAH are local. That matters more on this pair than on a same-zone hop.
When SAN–IAH 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 San Diego to Houston
