Los Angeles to San Francisco: notes from our team
The short version
340 miles, about 1h 11m in the air, nonstop on Alaska Airlines, Delta Air Lines and United Airlines. It's the kind of route where prices look calm for weeks and then jump in a day — the fares above are live, and when they're low, they don't stay low.
How we'd book it
Right now, December 2026 is the cheapest month we're tracking on this route, from $18. Book 2–4 weeks out for the best shot at the low fares, and don't leave it to the last two weeks — that's when this route's prices step up.
We'd also price the ticket with a checked bag before choosing — on this route the "cheapest" option flips once bags are in, more often than you'd think. Every carrier's real charges are in our airline guides; thirty seconds there saves the surprise at the airport.
The ground game
Two hours at LAX. No shortcuts, no "it'll be fine" — the one part of this trip you can't rebook is the security line. Ground transport, parking and terminals are covered in our Los Angeles airport guide and the San Francisco airport guide. Headed back the other way? San Francisco to Los Angeles fares are tracked separately — the cheap days rarely line up both ways.
One last thing
If your dates can slide a day either way, slide them. On a route like this, a Tuesday departure and a Thursday departure can be two different prices for the same seat — flexibility is the cheapest upgrade there is.
