San Francisco SFO to Las Vegas LAS Flights: Nonstop Guide

San Francisco to Las Vegas takes about 1 hour 30 minutes to 1 hour 50 minutes nonstop, and there is no time change because Nevada and California are both on Pacific time. As of recent schedules, United, Alaska and Southwest fly SFO to Harry Reid International (LAS) nonstop. Oakland and San Jose add more nonstops, mainly on Southwest. Check the airline's timetable for your dates, since frequencies change by day and season.

Who flies SFO to Las Vegas nonstop

• United runs its Bay Area hub at SFO and flies to Las Vegas several times a day, mainly from Terminal 3.
• Alaska, now SFO's second-largest airline, flies from Harvey Milk Terminal 1, where it moved in 2024.
• Southwest also flies the route; confirm its SFO terminal on your boarding pass, since terminal assignments at SFO have shifted in recent years.

The flight is short enough that the time you spend getting to the airport and through security matters more than the time in the air, so the closest Bay Area airport is often the best choice.

SFO, Oakland or San Jose?

• San Francisco (SFO) suits San Francisco and the Peninsula, and BART runs straight into the International Terminal.
• Oakland (OAK) suits the East Bay. Southwest is the largest airline there and flies to Las Vegas nonstop; BART reaches the terminal on a connector train from Coliseum station.
• San Jose (SJC) suits Silicon Valley and the South Bay, with Las Vegas nonstops led by Southwest.

Search all three in the fare grid. A Friday evening flight from the airport closest to your office can beat a cheaper one across the bay once you count the drive.

Getting to SFO without a car

BART runs from San Francisco, Oakland and the East Bay directly into SFO's International Terminal, and the AirTrain carries you from there to Terminals 1, 2 and 3. From the Peninsula and San Jose, Caltrain connects with BART at Millbrae, one stop from the airport. Parking at SFO fills on holiday weekends, so taking BART for a Las Vegas weekend often removes the most stressful part of the trip.

Flying vs driving

The drive from San Francisco to Las Vegas is roughly 570 miles and takes about 8 to 9 hours with clear roads, across the Central Valley and the Mojave Desert. For a weekend trip the flight saves most of a day each way. Driving makes sense only if you plan to stop in Yosemite, Death Valley or elsewhere on the way.

Leaving from SFO

SFO's terminals are linked airside, and the free AirTrain connects all terminals, the rental car center and BART. For a domestic flight, arrive about 90 minutes to 2 hours before departure. Morning fog and low clouds, most common in summer, can reduce SFO's arrival capacity and delay outbound flights through the day; an early departure usually avoids the worst of it. TSA PreCheck lanes are open in every terminal; see our Global Entry vs TSA PreCheck guide. Our SFO airport guide has more.

Arriving at Harry Reid International (LAS)

Las Vegas has two terminals that are not connected landside. Terminal 1 handles Southwest, Delta and American; Terminal 3 handles United, Frontier, Alaska and JetBlue. Each has its own baggage claim and pickup areas, so your ride needs to know which one you are at.

• Taxis wait at marked stands outside baggage claim at both terminals, and the Strip is a short ride away.
• Rideshare pickup is in the parking garages, signposted from baggage claim.
• RTC public buses serve the airport for the Strip and downtown.

Taxi lines grow long on Friday evenings and when a big convention lets in.

ID at the checkpoint

There is no passport check on a flight inside the US, but TSA has required a REAL ID-compliant license or another accepted ID, such as a US passport, since May 7, 2025. A California license needs the bear-and-star REAL ID mark. If you have no acceptable ID, TSA ConfirmID is a paid alternative that adds time; check the fee on tsa.gov. Our REAL ID guide covers the details.

Flying home: Las Vegas to the Bay Area

The return is about the same length, but the airport is busier: Sunday afternoons and Monday mornings at LAS bring long security lines as the weekend crowd leaves together. Terminal 1 and Terminal 3 have separate checkpoints, so go straight to the one your airline uses, and return any rental car early, since the rental car center is a shuttle ride from both terminals. If your flight is delayed into the evening, fog at SFO is less common than in the morning, but Oakland and San Jose are useful backups on Southwest.

Bags and cheapest fares

On a short weekend route, the bag rules often decide which fare is cheapest in practice. Southwest includes a carry-on on every fare but, since May 2025, charges for checked bags on most fares, and since January 27, 2026 it assigns seats. Alaska's Saver fare includes a carry-on. United Basic Economy includes only a personal item on domestic routes. See airline baggage rules and basic economy explained.

Best time to fly to Las Vegas

Las Vegas demand follows weekends and events more than seasons. Thursday and Friday departures from the Bay Area and Sunday returns fill first; Tuesday and Wednesday are usually quieter. March to May and October to November have the most comfortable weather, while summer afternoons in the desert are well over 100°F. Large conventions, such as CES in early January, fill hotels and flights alike, so check the city's convention calendar before you pick dates.

Tips for this route

• Pick the Bay Area airport closest to you; on a flight this short, the drive matters most.
• Fly early from SFO in summer to avoid fog delays.
• Pack carry-on only for a weekend and skip both baggage claims.
