The Houston–San Diego route
George Bush Intercontinental (IAH) to San Diego International (SAN) covers about 1,301 miles. Nonstop IAH–SAN is often on the schedule, about 3 hours airborne over 1,301 miles. This page is a US-market guide in USD — not a ticket and not a live calendar.
For IAH–SAN we show about $109 on the low end and around $190 as a more typical one-way economy total, USD, last reviewed August 2026. A $109 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 IAH 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 IAH–SAN
Great-circle distance IAH–SAN 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.
San Diego is about 2 hours behind Houston on standard time (America/Chicago vs America/Los_Angeles). Arrival clocks on SAN are local. That matters more on this pair than on a same-zone hop.
When IAH–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 Houston to San Diego
Both ends are in the United States: George Bush Intercontinental (IAH) 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.
IAH is the only origin code we list in this metro. 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.
