Distance and time SAN–ORD
Great-circle distance SAN–ORD is about 1,720 miles. Block time on a nonstop is typically near 4 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.
Chicago is about 2 hours ahead of San Diego on standard time (America/Los_Angeles vs America/Chicago). Arrival clocks on ORD are local. That matters more on this pair than on a same-zone hop.
When SAN–ORD 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 Chicago
Both ends are in the United States: San Diego International (SAN) to O'Hare International (ORD). 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.
SAN is the only origin code we list in this metro. On arrival, MDW (Chicago) can price differently from ORD. 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.
