San Francisco to Los Angeles is one of the busiest air corridors in the United States — a quick hop of about 90 minutes with departures nearly every half-hour. Six airlines compete hard on it, so fares stay low and flexibility is easy. This guide covers who flies it, what a fair round-trip costs in dollars, and how to lock in the cheapest seats on a route where the deals are almost always there.

Fares from San Francisco to Los Angeles (USD)
This is a value route year-round: with six carriers and hundreds of weekly flights, there’s rarely a bad time to fly, and last-minute seats are usually available. Fares tick up around the summer travel season and the winter holidays, and midweek is almost always cheaper than a Friday or Sunday. The figures below are typical economy round-trip fares in dollars — the lowest are the basic/no-frills tickets on Frontier and the budget fare buckets of the big carriers.
| Month | Typical return (economy) | Demand |
|---|---|---|
| January | $80 – $150 | low-medium |
| February | $70 – $140 | low |
| March | $80 – $160 | medium |
| April | $80 – $160 | medium |
| May | $90 – $170 | medium |
| June | $100 – $190 | medium-high |
| July | $110 – $200 | high |
| August | $110 – $200 | high |
| September | $90 – $170 | medium |
| October | $90 – $170 | medium |
| November | $100 – $190 | high (Thanksgiving) |
| December | $110 – $210 | high (holidays) |
Reference points from our own deal tracking and current schedules: a strong round-trip lands around $60–$90, a typical fair price is roughly $110–$130, and one-way fares regularly show up under $40 on Frontier and the airlines’ basic-economy buckets. Anything below about $90 return is a good grab.
Airlines on this route
Non-stop (about 90 minutes):
- United — SFO is a United hub, so it runs frequent shuttle-style service throughout the day.
- Alaska Airlines — a strong Bay Area presence with dozens of weekly flights and a well-regarded loyalty program.
- American Airlines — frequent non-stops feeding its Los Angeles operation.
- Delta — multiple daily departures, often competitive on price and reliability.
- Southwest — two free checked bags and no change fees; good value if you’re carrying luggage.
- Frontier — the ultra-low-cost option with the cheapest headline fares; expect to pay separately for bags and seats.
With this much competition there’s no meaningful time penalty for shopping around — every carrier covers the route in roughly the same 90 minutes. Pick on price, schedule and bag policy: Southwest for free bags, Frontier for the rock-bottom base fare, the big three for hub connections and status.
When to book & how to save
- Book 2–6 weeks ahead for the best fares; unlike long-haul, this route often stays cheap even fairly close in because of the sheer number of seats.
- Fly midweek: Tuesday and Wednesday departures are usually the cheapest, while Friday and Sunday carry the biggest premium.
- Compare all-in prices on the ultra-low-cost fares: Frontier’s base fare is tempting, but a carry-on and seat can erase the savings versus Southwest (two free bags) or a basic-economy ticket on the majors.
- Consider Bay Area alternates: Oakland (OAK) and San Jose (SJC) also serve Los Angeles and Southern California and can be cheaper — and Burbank (BUR), Long Beach (LGB) and John Wayne (SNA) are handy LA-area alternatives to LAX.
- Off-peak flights save money: the first and last departures of the day are often the lowest-priced, and avoiding the summer and holiday peaks helps.
Arriving in Los Angeles
Flights land at Los Angeles International (LAX), about 18 miles southwest of downtown. From the terminals, the free shuttle to the Metro C Line connects to the rail network for a low-cost ride into the city (a Metro fare is under $2, though transfers make it slow). Most travelers use a ride-hail or taxi from the designated LAX-it lot — expect roughly $30–$60 to downtown or the Westside depending on traffic and time of day. The newer Automated People Mover links the terminals to the consolidated rental-car center and a Metro station, making transit connections easier than in the past.
