Distance and time BWI–SFO
Great-circle distance BWI–SFO is about 2,451 miles. Block time on a nonstop is typically near 5.5 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.
San Francisco is about 3 hours behind Baltimore on standard time (America/New_York vs America/Los_Angeles). Arrival clocks on SFO are local. That matters more on this pair than on a same-zone hop.
When BWI–SFO 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 Baltimore to San Francisco
Both ends are in the United States: Baltimore/Washington International (BWI) to San Francisco International (SFO). 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.
Near Baltimore, also compare DCA (Washington), IAD (Washington). SFO is the arrival code we treat as primary for San Francisco. 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.
