The cheapest way to get from San Francisco to Los Angeles (2026)
San Francisco to Los Angeles is one of the most-traveled corridors in the country, and you've got five real ways to make it: fly, drive solo, take the bus, take the train, or carpool. Here's what each actually costs — all-in, not just the sticker price — and which one wins for your trip.
Quick comparison
| Option | All-in cost | Door-to-door time | Best for |
|---|---|---|---|
| Bus (FlixBus / Greyhound) | $20–$50 | 8–9 hrs | Lowest ticket, if you have the time |
| Carpool (Seat Sherpa) | $40–$55 / seat | ~6 hrs | Cheap + fast, dropped near your destination |
| Drive solo | $50–$70 gas + parking | ~6 hrs | Total flexibility, if you don't mind driving |
| Fly | $60–$150 + bags | 4–5 hrs | Fastest, if you catch a cheap fare |
| Train (Amtrak) | $50–$120 | 11+ hrs | The scenery — not the speed |
The bus: cheapest ticket, longest day
FlixBus and Greyhound run SF → LA for as little as $20–$50 if you book ahead. The catch is time: 8–9 hours on a fixed schedule, plus getting to and from the bus terminals on each end. If your only goal is the lowest possible price and you can spare the day, the bus wins on the ticket.
Flying: fastest in the air, slow on the ground
SFO/OAK/SJC to LAX/BUR is only about 90 minutes in the air, and fares start around $60 — but the real number is higher once you add a checked bag ($35+), getting to the airport an hour or two early, and a ride from LAX on the other side. Door-to-door you're usually looking at 4–5 hours and $100+ all-in. Great when you find a genuinely cheap fare; less magical than it sounds otherwise.
Driving solo: flexible, but you pay for the whole tank
It's ~380 miles down I-5, about 6 hours. Fuel alone runs $50–$70 depending on your car and gas prices, before wear, tolls, and LA parking. You control the schedule and can stop wherever — but you're covering 100% of the cost and doing all the driving.
The train: beautiful, not practical
There's no fast direct Amtrak between SF and LA. The Coast Starlight is a scenic 11+ hour ride, and most "SF–LA" Amtrak trips involve a bus connection. Take it for the coastline, not to get somewhere on time.
🚗 The sweet spot: carpool
A carpool lands in the gap everything else misses — nearly bus-level price at roughly car-level speed. On Seat Sherpa you ride with someone already making the drive and split their gas at $40–$55 per seat, get there in about 6 hours, and get dropped closer to where you're actually going instead of an airport or bus terminal. No surge, no markup — you're sharing the real cost of a trip that's happening anyway.
See SF → LA ridesSo which is cheapest?
Strictly by ticket price, the bus is cheapest — if you can give up the day. If you want cheap and fast, a carpool is the best-value option for most people: close to the bus on price, close to driving on time, and it drops you at a real address instead of a terminal. Flying only wins when you snag a rock-bottom fare and truly need the speed.
