Airlines on This Route
- United Airlines (direct): from $310 — United has the most frequency on this route. Check United’s app for error fares – they occasionally discount SFO-LAX to €120 in off-peak.
- Southwest Airlines (direct): from $290 — Southwest is consistently cheapest. Book on Tuesdays at 9am PT when they release sales. Rapid Rewards points are valuable at 1.4-1.6 cents per point.
- Delta Air Lines (direct): from $330 — Delta often matches United on price but offers better onboard service. Check Delta’s Lie Flat seats on this route if you want premium.
- American Airlines (direct): from $305 — AA has fewer SFO-LAX frequencies than United but often has better exit row availability. Book 21 days out for Main Cabin deals.
- Alaska Airlines (direct): from $300 — Alaska offers the most legroom in Main Cabin (31-32 inches) on this route. MVPs get free upgrades, often clears on this short hop.
- JetBlue Airways (direct): from $285 — JetBlue has the most comfortable seats (34-inch pitch in Mint). Check their ‘Blue Flex’ fares for maximum flexibility.
- Spirit Airlines (connecting): from $220 — Only worth it if booking 2+ months out for the cheapest fares. Factor in bag fees – Spirit often matches Southwest when those bags are added.
Booking Strategy
The SFO-LAX route is one of the busiest domestic corridors in the US, with over 100 daily flights, making competition fierce and deals relatively common. The sweet spot for booking is 2-4 weeks ahead for standard Economy fares – any earlier and you’re paying premium, any later and prices spike. Tuesday and Wednesday flights are consistently $40-80 cheaper than Friday-Sunday. For the cheapest fares, set Google Flights alerts for SFO-LAX at $180 or below – this triggers roughly 2-3 times monthly. Southwest releases their schedule 6 months out and has sales every Tuesday, so if you can plan ahead, Southwest bookings made 3-5 months out at their Tuesday sales are unbeatable. Avoid booking on Fridays – prices are statistically 15% higher. If flying carry-on only, JetBlue and Southwest both include this in base fares, while Spirit and Frontier charge extra. The cheapest time to fly is early morning (6-8am) or late evening (8pm+).
Route Tips
- For SFO departures, Terminal 3 (United/Delta) and Terminal 2 (Southwest/American) are adjacent – allow 20 minutes to walk between them if transferring. Terminal 1 (Alaska/JetBlue) is separated and requires a bus or train.
- LAX is undergoing massive renovation – Terminal 6 now has a dramatically improved layout, but check which terminal your airline uses as changes happen frequently.
- If driving from LAX to downtown LA, avoid the 405 freeway between 3-7pm – the 105 to 110 to 5 or taking surface streets (Sepulveda) is often faster despite being longer in miles.
- This route is so short that most airlines don’t offer WiFi or seatback entertainment – bring downloaded movies or podcasts. United and Delta have WiFi but it’s not worth the $8 fee for a 1h15m flight.
- For LA-bound business travelers, LAX is closer to the Westside (Santa Monica, Century City), while Burbank Airport (BUR) is better for Downtown LA and the Valley – check if BUR has SFO service on JetBlue.
Frequently Asked Questions
How long is the flight from San Francisco to Los Angeles?
The direct flight time is just 1 hour 15 minutes to 1 hour 30 minutes, making it one of the shortest commercial flights in the US. United, Delta, American, Alaska, Southwest, and JetBlue all operate direct flights roughly every 30-60 minutes throughout the day. If booking a connecting flight (usually through Las Vegas, Phoenix, or Denver on Spirit or Frontier), expect 2.5 to 5.5 hours depending on layover duration. Note that due to short duration, no in-flight entertainment is offered on most carriers – bring your own device or book United/Delta for seatback screens.
How much does it cost to fly from San Francisco to Los Angeles?
Economy fares range from $180 to $450 depending on season and advance booking. The cheapest deals ($180-$250) are typically found on Southwest, JetBlue, or Spirit in January-February or October-November. Peak summer (June-August) sees prices climb to $350-$430, while holiday periods in December hit $370-$450. Basic Economy on legacy carriers strips you to just a personal item, while Southwest and JetBlue include a full carry-on. At $300 base price, you’re looking at standard Economy with 3-4 weeks advance booking – reasonable but not the cheapest available.
Are there direct flights from San Francisco to Los Angeles?
Yes, absolutely – direct flights are the norm on this route, not the exception. Over 100 direct flights operate daily between SFO and LAX. United dominates with the most frequencies (roughly 35 daily), followed by Southwest (25+), American (20+), Delta (15+), Alaska (10+), and JetBlue (8-10). Flight times are remarkably consistent at 1h 15m-1h 30m regardless of carrier. There is no need to book a connecting flight unless you’re specifically seeking the absolute rock-bottom fare on Spirit or Frontier, which may route through Las Vegas.
What is the cheapest month to fly from San Francisco to Los Angeles?
January and February are the cheapest months, with average fares dropping to $265-$280 – roughly 35-40% below peak summer pricing. This coincides with the post-holiday travel slump when business and leisure travel both slow down. October also offers excellent value at $290 average, as kids return to school and summer tourism winds down. The most expensive period is June through August ($390-$430 average) when families take summer vacations, followed by mid-December around the holidays ($370+). For best deals, target Tuesday-Wednesday flights in midweek off-season.
Which airlines fly from San Francisco to Los Angeles?
Six carriers operate direct service: United Airlines (most frequent, hub connection), American Airlines, Delta Air Lines, Alaska Airlines, Southwest Airlines, and JetBlue Airways. Budget carriers Spirit Airlines and Frontier sometimes offer cheaper base fares but typically include a connection via Las Vegas. Southwest and JetBlue offer the best value for carry-on bags included in all fares. Alaska offers the most legroom in Economy (31-32 inches). United and Delta provide the most premium options including first class on some flights. For the absolute cheapest all-in price, compare Southwest’s $290 fare with Spirit’s $220 base + bag fees.
What airport do I fly into in Los Angeles?
All flights from San Francisco arrive at Los Angeles International Airport (LAX), located approximately 15 miles (24 km) southwest of downtown LA. LAX is the primary international gateway to Southern California and the second-busiest airport in the US. From LAX to downtown LA, ride-shares (Uber/Lyft) cost $25-45 depending on traffic, taxis are approximately $50-60 flat rate, and the FlyAway bus is $10 (runs 24/7 to Union Station). Renting a car at LAX is popular but note the $4.50/day facility charge added to all rentals. Allow 30-60 minutes for ground transport depending on time of day – LA traffic is notoriously bad between 7-10am and 3-7pm.
How far in advance should I book San Francisco to Los Angeles flights?
For this domestic route, booking 2-4 weeks ahead gives the optimal balance of availability and price. Book further out (6+ weeks) only if Southwest has a sale or you need specific departure times. Unlike international routes, booking 2+ months ahead rarely yields discounts – carriers know this is a high-demand business and leisure corridor. However, waiting until the last 3-7 days is risky as prices often spike $100+ for same-day inventory. The exception is if you’re flexible – airlines sometimes release unsold seats at discounted rates 2-3 days before departure. For holiday periods (Thanksgiving, Christmas, Spring Break), book 6-8 weeks ahead as prices climb sharply closer to those dates.
Is it cheaper to fly from San Francisco to Los Angeles on weekdays?
Yes, flying midweek is noticeably cheaper on this route. Tuesday and Wednesday are the cheapest days to fly, with fares typically $40-80 lower than Friday through Sunday. This reflects the business traveler pattern – Monday and Friday see higher demand from business travelers heading to/returning from LA for work weeks. Saturday sits in the middle. Sunday evening flights returning from LA tend to be the most expensive as weekend travelers head home. For the best combination of cheap and convenient, Tuesday or Wednesday departures between 9am-2pm offer the lowest fares with good frequency. Weekend travelers can save significantly by returning Monday instead of Sunday.
