💰 When is the cheapest time to fly from Los Angeles to San Francisco?
This month: Average $198 round trip. July 1-5 hits $260; mid-to-late July $180-$210.
LAX-SFO fares stay remarkably stable year-round because business demand smooths seasonal swings. Expect $118-$180 round trip most months, with three predictable spikes: Thanksgiving week ($240-$320), the December 22-26 corridor ($260-$340), and the July 1-5 holiday window ($200-$260). January and February are the cheapest months as business travel slows and tourists avoid SF fog season. October is the sleeper month — perfect weather in both cities, business demand normal, fares 15-20% below summer averages.

Here's a month-by-month look at prices on this route:
✈️ Which airlines fly from Los Angeles to San Francisco?
Five carriers compete on LAX-SFO, but only three matter for most travelers. United owns the frequency and SFO hub access. Southwest owns the bag-included total-cost equation. Alaska owns the points-and-miles game for West Coast loyalists. Delta is the premium reliability play. JetBlue's 4 daily flights make it an afterthought unless you're already a Mosaic elite. Spirit and Frontier skip SFO entirely — they fly LAX-OAK instead, which only works if Oakland is your actual destination.
United is the only true shuttle on LAX-SFO. 18 daily flights from LAX Terminals 7/8 to SFO Terminal 3 (United's hub), with hourly departures 6am-9pm. If your meeting runs long, you swap to the next flight for $75 — no other carrier offers this flexibility. Avoid basic economy: no seat selection, no overhead bin access, and on a 1h 25m flight, the $30 main cabin upgrade is worth every penny. Economy Plus seats (35-inch pitch) are the smart business buy at $25-$45 extra.
Best for: business travelers needing hourly cadence, SFO hub connectors, MileagePlus elites
Southwest wins on total cost when bags enter the equation. 12 daily flights from LAX Terminal 1, two free checked bags, and no change fees. The open seating model is a non-issue on a 1h 25m flight — sit anywhere, you're landing in 80 minutes. Book Wanna Get Away Plus for early bird check-in ($15) if window seats matter. Rapid Rewards points earn at 6-10x per dollar on Wanna Get Away fares, and Companion Pass holders fly a second person for $5.60 in taxes.
Best for: families with luggage, leisure travelers, Companion Pass holders
Delta runs the most reliable operation on this route — 84% on-time per DOT 2025 data, beating United's 78%. 9 daily flights from LAX Terminal 2/3 to SFO Terminal 2. The premium positioning shows up in pricing: expect to pay $20-$40 more than United for an identical itinerary. Worth it if on-time arrival is mission-critical. Skip basic economy here too — Delta is the strictest enforcer of the no-overhead-bin rule, and gate agents will tag your roller bag.
Best for: reliability-first travelers, SkyMiles loyalists, Amex Platinum cardholders
Alaska is the points-hoarder's choice on LAX-SFO. 6 daily flights from LAX Terminal 6, Mileage Plan miles redeem at 1.4-1.8 cents each, and the Bank of America Alaska Visa companion fare ($122 plus taxes) effectively halves the cost of a couple's trip. Service quality matches Delta with friendlier crews. The oneworld partnership lets MileagePlus is dead-and lets you earn AAdvantage miles on these flights. Avoid saver fares — same basic-economy restrictions as United.
Best for: Mileage Plan loyalists, Bank of America Alaska cardholders, points hoarders
JetBlue is an afterthought on LAX-SFO with only 4 daily flights. From LAX Terminal 5 to SFO Terminal 2, 32-inch seat pitch (best in economy on this route), and free fast Wi-Fi. The frequency problem kills it for business — if your flight cancels, you're waiting 3-5 hours for the next JetBlue option. Only worth booking if you're a TrueBlue Mosaic elite or specifically need the Wi-Fi for working en route. Most travelers should default to United, Southwest, Delta, or Alaska first.
Best for: Mosaic elites, free in-flight Wi-Fi seekers, JFK connectors
Mubboo verdict: Fly United for frequency and SFO hub access, Southwest for bag-heavy travel, Alaska for points. Skip basic economy on business trips.

Book LAX-SFO 21-45 days ahead for the lowest economy fares — $118-$160 round trip. This route doesn't reward early booking the way long-haul does. Fares stay flat from 90 days to 45 days, dip slightly in the 21-45 day window as carriers manage load factors, then spike hard inside 14 days to $280-$420. The day-of-week pattern matters more than the booking window: Tuesday/Wednesday departures run $59-$89 one-way, while Friday 3pm-7pm and Sunday 5pm-9pm hit $180-$240 because business travelers fuel return-leg demand. Set a Google Flights alert at 60 days out, pull the trigger when you see $120-$140 round trip, and don't second-guess. For same-week bookings, Southwest's Wanna Get Away fares are typically the cheapest last-minute option at $99-$140 one-way.
July 4 week is the year's second-most-expensive — beyond that, summer leisure keeps fares elevated.
If you're a family flying in summer, book by March — peak season fills up fast.
Budget travelers: shoulder season (Sep–Oct, Apr–May) offers the best balance of price and weather.
💡 This Jul: Book July 4 corridor 90+ days ahead; rest of month 45 days.

✈️ Travel tips for Los Angeles to San Francisco
TSA PreCheck is non-negotiable for this route. Without it, LAX security averages 45-90 minutes during peak hours (6am-9am, 3pm-7pm). With PreCheck, you're through in 5-15 minutes. If you fly LAX-SFO 3+ times per year, Global Entry ($120 for 5 years, includes PreCheck) pays for itself in saved time on the first round trip. Clear is a worthwhile upgrade at LAX Terminals 1, 2, 3, 4, 5, 6, 7, and B — stacks with PreCheck for a 2-5 minute total clearance. Multi-airport strategy: don't switch SFO for OAK or SJC unless your destination is East Bay or South Bay specifically. Spirit and Frontier fly LAX-OAK with rock-bottom fares, but BART transfer time and bag fees erase the savings. For Marin or North Bay, SFO is your only realistic choice. Loyalty earning strategy: stack one carrier on this route to hit elite status fast. 8-10 LAX-SFO round trips per year qualifies you for United Premier Silver (28,000 PQM annually), Alaska MVP (20,000 miles), or Delta Silver Medallion (depending on segments). For credit card earning, the Bank of America Alaska Visa companion fare and Chase Sapphire Preferred 3x on travel are the two highest-value plays. Skip earning Delta SkyMiles on short-haul — the redemption rate is poor under 1.0 cent per mile.

Search flights →🛫 Flying from Los Angeles — airport tips
LAX Terminal 1 — Southwest (Southwest Airlines)
- Use the Sepulveda Boulevard underpass entry, not the upper-level departure ramp — saves 15-25 minutes in peak traffic
- Security averages 15-25 minutes off-peak, 35-45 minutes during 6am-9am rush
- Earl's Gourmet Grub past security has the best pre-flight breakfast on the LAX domestic side
LAX Terminals 7/8 — United (United Airlines)
- United Club access via MileagePlus Premier 1K, Star Alliance Gold, or United Club Card — best showers at LAX in Terminal 7
- Premier Access security line cuts wait from 45 min to 10 min for Premier Silver+ and first-class passengers
- Gates 70-77 are the SFO shuttle gates — closest to security, fastest boarding
LAX Terminal 6 — Alaska (Alaska Airlines)
- Alaska Lounge access via MVP Gold 75K, First Class same-day, or Alaska Lounge membership ($550/year)
- Terminal 6 connects to Terminal 5 (JetBlue, Delta) airside via a connector — useful if you misread your boarding pass
- Security averages 20-30 minutes; Clear lanes available and stack with TSA PreCheck for 2-5 minute total
SFO Terminal 3 — United Hub (United Airlines)
- BART station is a 10-minute AirTrain ride from Terminal 3 to International Terminal G — total trip downtown 35-40 minutes for $11
- United Polaris Lounge access requires international business class — domestic shuttle passengers use United Club
- Yankee Pier oyster bar past security in Terminal 3 is the best post-flight stop if your meeting is downtown
💡 Insider tips: Los Angeles to San Francisco
Lead with Tuesday/Wednesday — save $80-$140 round trip versus weekend bookingsMubboo original data
Shift your trip by one day to crack the fare code. Tuesday and Wednesday departures across all four major carriers average $59-$89 one-way, while Friday 3pm-7pm and Sunday 5pm-9pm runs $180-$240. For a round trip, that's an $80-$140 swing — more than the cost of a checked bag, an Uber, or an extra hotel night. Business travelers locked to Monday/Friday cycles can't escape this, but anyone with calendar flexibility should default to a Tuesday morning departure and Wednesday or Thursday return.
Use Sepulveda Boulevard underpass to skip LAX horseshoe traffic at Terminal 1Mubboo original data
LAX's horseshoe layout creates 30-60 minute backups during peak hours. Southwest passengers at Terminal 1 can bypass the entire mess by using the Sepulveda Boulevard underpass entry — turn off Sepulveda directly into Terminal 1's lower-level arrivals, then walk up one floor to departures. Saves 15-25 minutes in peak traffic. Terminals 2-8 don't have this escape valve. Drop-off at the Lyft/Uber zone outside Terminal 1 (LAX-it shuttle area) adds another 10 minutes — use a personal drop-off at the underpass entry instead.
Skip Spirit and Frontier — they fly LAX-OAK, not LAX-SFO
Don't fall for the $39 ultra-low-cost teaser fares. Spirit and Frontier don't operate LAX-SFO at all — they fly LAX-OAK (Oakland) instead. If your destination is downtown San Francisco, OAK adds 45-60 minutes of ground transit via BART ($11) plus a transfer, erasing any time savings. Add Spirit's $35-$65 bag fees and $20 seat selection, and the $39 fare becomes $140+ for a worse experience. Only book LAX-OAK if Oakland or East Bay is your actual destination.
BART beats Uber from SFO to downtown — $11 versus $35-$55
Take BART, not Uber, from SFO unless you have 3+ bags or are heading to a non-BART neighborhood. BART connects SFO International Terminal G directly to downtown SF in 30 minutes for $11 per person. Uber from SFO to downtown runs $35-$55 depending on surge, and you'll sit in 101 traffic for 25-45 minutes anyway. For Mission, SOMA, Financial District, or anywhere along Market Street, BART wins on every dimension. Uber wins only for Marina, Pacific Heights, or late-night arrivals after BART closes at midnight.
United Economy Plus is the smart business buy at $25-$45 extra
Skip basic economy on business trips; skip first class on this short flight. Basic economy means no seat selection, no overhead bin access, and last boarding — on a 1h 25m flight, you'll spend more time stressing about the bin than flying. First class at $280-$420 one-way is overkill for 80 minutes airborne. Economy Plus (35-inch pitch, dedicated overhead bin, Group 2 boarding) at $25-$45 extra is the sweet spot. Same logic applies to Delta Comfort+ and Alaska Premium Class on this route.
Bank of America Alaska Visa companion fare pays for itself in one LAX-SFO trip
The $95 annual fee Alaska Visa includes a $122 companion fare each cardholder anniversary. Use it on LAX-SFO and your second passenger flies round trip for $122 plus taxes — versus paying $118-$240 separately. The card also earns 3x miles on Alaska purchases and 1x everywhere else. Pair it with Mileage Plan elite status (MVP at 20,000 miles annually, easy for LAX-SFO regulars) and you'll earn free upgrades, free checked bags, and Premium Class seating. The math beats Chase Sapphire for West Coast frequent flyers.
👥 Who flies this route — and what they should know
Family with checked bags
Featured this monthRecommended: Southwest from LAX Terminal 1, midday off-peak departure. Two free checked bags per passenger means a family of four flies with 8 free bags — versus $320 in bag fees on basic economy fares elsewhere. Mubboo Pick: Southwest Wanna Get Away Plus with EarlyBird Check-In ($15 per person) — locks in adjacent seats without paying full Anytime fare. Book the 11am or 1pm flight to avoid the 6am-9am LAX rush. Kids under 6 board with families during Family Boarding (between A and B groups). Rapid Rewards points earn at 6-10x per dollar, and Companion Pass holders fly a second adult for $5.60 in taxes. Total cost for a family of four round trip: $480-$640, versus $720-$960 on legacy carriers.
Business commuter same-day return
Recommended: United from LAX Terminals 7/8, 7am departure, 6pm return. United's 18 daily flights and hourly cadence are the only product built for same-day SF turnaround. Book main cabin (not basic economy) so you can change to an earlier or later flight for $75 if your meeting timing shifts. Mubboo Pick: United Economy Plus at $25-$45 extra delivers 35-inch pitch and Group 2 boarding — the only product that respects your calendar. Hit LAX by 5:45am for the 7am departure, land SFO by 8:35am, BART to Embarcadero by 9:15am. For the return, the 6pm shuttle gets you home by 8pm. MileagePlus Premier members get free Economy Plus seats — earn status fast on this route with 4 PQF per round trip.
Points-hoarder West Coast loyalist
Recommended: Alaska Airlines from LAX Terminal 6, Tuesday or Wednesday departure. Alaska Mileage Plan miles redeem at 1.4-1.8 cents each on partner awards — better than United MileagePlus (1.1-1.3 cents) and far better than Delta SkyMiles. Mubboo Pick: pair Alaska Visa (Bank of America) with MVP status — the $122 companion fare alone covers a full LAX-SFO round trip for your partner. Earn 1x mile per dollar on saver fares, 2x on main cabin. MVP elites (20,000 annual miles, attainable with 8-10 LAX-SFO round trips) get free Premium Class upgrades and free checked bags. The oneworld partnership lets you credit these flights to AAdvantage if you're an American Airlines elite instead.
Reliability-first SkyMiles loyalist
Recommended: Delta from LAX Terminal 2/3, morning departure 7am-10am. Delta's 84% on-time rate beats United (78%) and Southwest (76%) per DOT 2025 data — worth the $20-$40 premium for travelers who can't afford a missed connection or late arrival. Mubboo Pick: Delta Comfort+ at $30-$50 extra delivers 34-inch pitch, free premium snacks, and dedicated overhead bin space — the most consistent short-haul premium economy product in the US. Amex Platinum cardholders get Delta SkyClub access ($695 annual fee) — the LAX SkyClub in Terminal 3 is one of Delta's best lounges. Skip basic economy on Delta specifically — they're the strictest enforcer of the no-overhead-bin rule, and gate agents will gate-check your roller bag at boarding.
Solo leisure traveler with carry-on only
Recommended: cheapest fare across United, Southwest, or Alaska — book Tuesday/Wednesday departure. Without checked bag concerns, the basic economy fare is the right call at $59-$89 one-way. Mubboo Pick: United basic economy from LAX Terminal 7 if cheapest, Southwest Wanna Get Away if within $10 — Southwest's open seating is a non-issue on 80 minutes airborne. Pack a 22-inch carry-on that meets all airline sizers (United and Alaska enforce; Southwest is loosest). Use the Hopper app to set a price alert at $120 round trip and pull the trigger when it hits. Solo travelers also have flexibility to book Saturday morning departures — $79-$110 one-way and a quieter cabin than weekday business shuttles.
⚖️ Flight delayed or canceled?
Under DOT 2024 rules, US carriers must provide automatic cash refunds (not vouchers) for canceled flights or delays exceeding 3 hours. This applies to all carriers on LAX-SFO. Additional rights: rebooking on the next available flight at no charge, meal vouchers for delays over 3 hours, and hotel accommodation for overnight delays caused by the airline. Weather and ATC delays don't trigger compensation but still qualify for the automatic refund if your flight is canceled. United's 18 daily flights give you the best rebooking flexibility during disruptions. Always file claims through the carrier first; escalate to DOT (transportation.gov/airconsumer) only if denied.
Frequently asked questions about Los Angeles to San Francisco flights
Flight time is 1h 25m northbound and 1h 30m southbound. The actual airborne time is closer to 55 minutes — the rest is taxi and approach sequencing at both airports.
Door-to-door, plan 5-6 hours: 60-90 minutes to LAX, 45-90 minute security depending on time of day, the flight itself, and 30-60 minutes from SFO via BART ($11) or Uber ($35-$55). For business travelers, flying still beats driving I-5 (5h 45m) but the margin is smaller than the airfare suggests.
