Carpool vs flying: San Francisco to Los Angeles and LA to Las Vegas
Short answer: flying is 2 to 3 hours faster door to door on San Francisco to Los Angeles and costs 2 to 4 times as much once bags and the airport legs are counted. A Seat Sherpa carpool seat is capped at $55 plus a 5% fee, leaves from a pickup point you agree in chat, and takes 6 to 7.5 hours. Flying wins on time; the carpool wins on money, luggage and everything around the flight.
The honest door-to-door numbers
| SF to LA | Flying (SFO/OAK to LAX/BUR) | Seat Sherpa seat |
|---|---|---|

| Bags | $35 to $80 for a checked bag on basic fares | Included by arrangement with the driver |
| Getting to and from airports | $30 to $90 in transit or rideshare, both ends | Pickup near you; drop-off arranged in chat |
| Time | 4 to 5 h door to door: 90-minute flight plus security and transfers | 6 to 7.5 h |
| Typical all-in | $150 to $350 | $35 to $60 |
LA to Las Vegas is closer: a 1-hour flight for $40 to $150 plus bags, about 3.5 to 4.5 hours door to door, against 4.5 to 5.5 hours and $25 to $55 plus fee in a carpool.
When to fly anyway
When the hours matter more than the money, when you are travelling light on a fare booked weeks out, or when a connection at the other end depends on a fixed arrival time. Weather rarely affects either option on these routes; I-5 traffic and airport security lines are the wildcards.

FAQ
Is it cheaper to fly or drive from San Francisco to Los Angeles?
Driving alone costs about $55 to $70 in gas and about $290 at the IRS mileage rate including wear. Flying is typically $150 to $350 all in with bags and airport transfers. A carpool seat splits the driver’s cost and is capped at $55 plus a 5% fee, which is the cheapest of the three.
How long does it really take to fly SF to LA?
The flight is about 90 minutes, but with getting to the airport, security, boarding and the trip in from LAX or Burbank, plan on 4 to 5 hours door to door. A carpool is 6 to 7.5 hours door to door.
How much does a Seat Sherpa seat cost?
It depends on the route and the driver, but every seat has a hard cap: the IRS standard mileage rate (about $0.76 per mile in 2026) multiplied by the drivable miles, divided across the seats, and never more than $55 a seat. Riders pay the seat price plus a 5% service fee, shown before you pay. Live prices for each corridor are on the route pages and in the ride browser.
Is Seat Sherpa safe?
Every driver verifies a phone number by SMS, uploads a driver’s license that is checked for expiry, registers the vehicle, and connects a Stripe account that verifies identity and bank details. Riders see the driver’s photo, trip count and reviews before booking, can filter for women drivers, and can block anyone. A 4-digit pickup code confirms the rider got in the car and is what releases payment.
What is the cancellation policy?
One standard policy on every ride: cancel 24 or more hours before departure for a full seat refund, 2 to 24 hours before for 50%, and inside 2 hours there is no refund. The 5% service fee is non-refundable when the rider cancels. If the driver cancels, the rider gets 100% back including the fee.
