Fares from Los Angeles to San Francisco (USD)
This is a year-round business shuttle as much as a leisure route, so fares track weekdays and holidays rather than any strong season. Late winter and early autumn tend to be the cheapest; summer and the December holidays the priciest. The figures below are typical economy return fares in dollars — with so many carriers competing, one-way sale fares under $50 are common.
| Month | Typical return (economy) | Demand |
|---|---|---|
| January | $100 – $170 | medium |
| February | $90 – $160 | low-medium |
| March | $100 – $180 | medium |
| April | $100 – $180 | medium |
| May | $110 – $190 | medium-high |
| June | $120 – $210 | high |
| July | $120 – $220 | high |
| August | $120 – $210 | high |
| September | $100 – $170 | medium |
| October | $100 – $180 | medium |
| November | $110 – $200 | high (Thanksgiving) |
| December | $130 – $230 | very high (holidays) |
Reference points from our own deal tracking: a genuinely good return lands around $100–$120, a typical fair price is roughly $140, and one-way fares as low as $40–$60 appear regularly on the budget carriers. Anything under about $120 return is a solid buy on this route.
Airlines on this route
Nonstop (about 1½ hours):
- United — the biggest operator, with a shuttle-style schedule and its main hub at SFO.
- Southwest — frequent nonstops, two free checked bags and no change fees; often the best all-in value.
- Alaska — multiple daily nonstops; a strong loyalty program and good main-cabin comfort.
- Delta — reliable frequent service with easy connections through its network.
- American — several daily nonstops from LAX.
- Frontier — ultra-low-cost nonstops with the cheapest headline fares; expect fees for bags and seats.
With this much competition there is no reason to connect — every itinerary worth buying is nonstop. Pick on price, schedule and whether you need a bag: Southwest bundles bags in, while the ultra-low-cost fares look cheapest until you add extras.
When to book & how to save
- Book 2–6 weeks ahead for the best fares; on a route this frequent, last-minute prices spike for business travellers.
- Fly midweek — Tuesday and Wednesday departures are usually the cheapest; Friday and Sunday carry the biggest premium.
- Compare all-in prices: an ultra-low-cost fare can end up dearer than Southwest once you add a bag and a seat.
- Avoid the peaks — summer, Thanksgiving week and late December are the busiest and most expensive.
- Travel light: with a flight this short, a carry-on-only fare on a full-service airline is often the smartest buy.
Arriving in San Francisco
Nearly all flights land at San Francisco International (SFO), about 21 km south of downtown. The easiest way into the city is BART, which has a station right at the international terminal and reaches downtown in around 30 minutes for about $10. A taxi or rideshare to downtown runs roughly $40–$65 depending on traffic. If your fare routes into Oakland (OAK) or San Jose (SJC) instead, both are also on BART or Caltrain connections but sit farther from central San Francisco.
