Distance and time SFO–IAH
Great-circle distance SFO–IAH is about 1,633 miles. Block time on a nonstop is typically near 3.5 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.
Houston is about 2 hours ahead of San Francisco 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 SFO–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 Francisco to Houston
Both ends are in the United States: San Francisco International (SFO) to George Bush Intercontinental (IAH). 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.
SFO is the only origin code we list in this metro. IAH is the arrival code we treat as primary for Houston. 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.
