Cheap flights from London to San Francisco
One-stop options: where to connect
These cities have nonstop flights both from London and to San Francisco with little detour, so they are common places to change planes when nonstop fares are high.
Smart ways to pay less on London–San Francisco
- Search the city code. Several airports serve this trip; searching LON → SFO shows them all at once.
- Only 3 airline(s) fly nonstop. Compare one-stop itineraries via Paris, Chicago, Frankfurt; they are often cheaper when nonstop competition is thin.
- Be flexible by a few days. Use the calendar view on the booking site; moving a departure by a day or two is usually the easiest saving.
- Consider one stop on long-haul. A connection through a big hub can cost much less than nonstop; keep it on one ticket with a sensible layover.
- Price two one-ways. Two one-way tickets, sometimes on different airlines, can beat a round-trip.
- No hidden-city tricks. Skipping legs breaks airline rules and can cancel your return flight.
