Los Angeles is one of the most aggressively competed airfare markets in the United States. Four commercial airports serve the greater LA basin, dozens of airlines fight for passengers on routes from every major city in North America, and the sheer volume of seats on offer means prices can move dramatically depending on when you search and which airport you choose. That competition is good news for travelers, but only if you know how to work the market. This guide covers everything you need to fly to LA without overpaying in 2026.

The Four Airport Question: LAX, Burbank, Long Beach, and Ontario

Most travelers default to Los Angeles International (LAX) without considering the alternatives, and for many routes that is the right call. LAX is the fifth-busiest airport in the world, and the sheer density of flights means competition keeps prices honest. But LAX is not always the cheapest option, and it is almost never the most convenient.

Hollywood Burbank Airport (BUR) sits in the San Fernando Valley, roughly 30 minutes from central Hollywood and the northern parts of the city. Southwest, United, and Alaska all fly here, and on routes from Seattle, Portland, San Francisco, and Phoenix, BUR fares frequently undercut LAX. The airport is far smaller, so the ground experience is faster, and rideshares run noticeably cheaper than from LAX. If your destination is the San Fernando Valley, Pasadena, Glendale, or the Westside reached via the 101, Burbank often wins on total door-to-door time.

Long Beach Airport (LGB) is compact, fast, and historically a Southwest stronghold. It sits 25 miles south of downtown LA, making it most useful for travelers heading to Long Beach itself, Anaheim, or Orange County destinations. On certain Southwest routes from the Bay Area and the Pacific Northwest, Long Beach prices have come in below LAX. Its curfew and slot limits constrain flight volume, so options are narrower.

Ontario International Airport (ONT) is 35 miles east of downtown LA in the Inland Empire. It is genuinely inconvenient for most LA visitors but makes sense if your final destination is Ontario, Riverside, or the eastern suburbs. Southwest, United, and Alaska all serve it. Fares here are sometimes significantly cheaper than LAX, particularly from hub cities in the South and Midwest, because the airport attracts a different, price-focused traveler mix. If you are renting a car and heading toward Palm Springs or the desert, Ontario can be a smart choice.

John Wayne Airport (SNA) in Orange County is the fifth option many guides miss. It serves Costa Mesa, Irvine, and Anaheim well, and for travelers going to Disneyland or the coastal communities of Orange County it can save an hour of ground transit versus LAX. American, Southwest, and Alaska fly here regularly, and fares from the Bay Area and Pacific Northwest are competitive.

Cheapest Months to Fly to Los Angeles

January and February are historically the cheapest months to fly to Los Angeles. The post-holiday demand slump hits LA as hard as any leisure destination, and airlines respond by discounting heavily on transcontinental routes and short-haul West Coast corridors. Bureau of Transportation Statistics fare data consistently shows Q1 as the lowest-price quarter for LA-bound travel across most origin markets. Fares from New York to LAX that might run $280 to $350 in peak season frequently drop to $150 to $200 in January.

June through August represents the peak season, driven by summer leisure travel, entertainment industry events, and beach tourism. Fares on the transcontinental corridors from New York and Boston climb steeply, and even regional routes from Seattle and San Francisco see elevated pricing. July and August are typically the most expensive months of the year on the NYC-LAX corridor.

September and October form the sweet spot that experienced LA travelers rely on. The summer rush has cleared, school is back in session, and leisure demand drops enough to pull prices down meaningfully below summer peaks. The weather in LA during September and October is arguably the best of the year: warm, dry, and clear. Fares from the East Coast during this window regularly run 15 to 25 percent below summer highs. October in particular is a reliable value month before Thanksgiving season drives prices up again.

November and December are split by the Thanksgiving and Christmas holiday spikes. The weeks between those holidays, roughly December 1 through December 18, can offer quieter fares on routes where demand has not yet reached holiday pressure. But book well in advance for the holiday travel windows themselves, as LAX fares around Thanksgiving and Christmas price like peak summer.

Best Airlines on Key Routes to LAX

Southwest Airlines is the dominant budget force on routes from the South and Midwest. Cities like Phoenix, Las Vegas, Dallas, Denver, Chicago Midway, and St. Louis see some of the lowest LAX fares on the market when Southwest is competing. Southwest does not appear on most third-party search engines, so always check southwest.com directly when flying from markets where they have strong service.

Alaska Airlines owns the West Coast corridor market. Seattle-LAX, Portland-LAX, and San Francisco-LAX are routes where Alaska has deep capacity and frequent competitive pricing. Alaska also flies nonstop from many smaller Pacific Northwest cities that other carriers skip, and its mileage program has historically rewarded West Coast travelers well. On Bay Area to LA routes, Alaska and Southwest together create a competitive pricing environment that keeps fares low relative to comparable distance in other markets.

JetBlue built its reputation on the transcontinental route from the East Coast, particularly from New York JFK and Boston. Its Mint business class product on the transcon is widely considered one of the best domestic premium products in US aviation, but its economy transcon fares also compete hard with American and United. JetBlue frequently offers promotional fares on the East Coast-LA corridor that undercut legacy carriers by $50 to $100.

American and United both have significant LA presence, with United operating a large hub at LAX and American connecting heavily through its Dallas and Phoenix hubs. Delta connects through Salt Lake City and its Atlanta hub to reach LA. On the transcontinental, all three compete seriously, and fare sales are frequent. Legacy carrier fares to LAX are often most competitive when purchased 4 to 8 weeks out, after initial pricing has had time to adjust to demand signals.

The NYC-LA Transcontinental: America's Most Competed Route

The New York to Los Angeles corridor, whether measured JFK-LAX, EWR-LAX, or JFK-BUR, is one of the most watched routes in US domestic aviation. It carries some of the highest passenger volumes in the country and attracts aggressive pricing from nearly every major carrier. JetBlue, American, United, Delta, and Spirit (when it was operating at full capacity) all competed on this corridor, and the competitive intensity has historically kept fares well below what distance alone would predict.

Typical round-trip economy fares on NYC-LAX range from $150 to $180 in the January-February trough to $300 to $400 during summer peak. The spread is wide, and the exact price depends heavily on how far in advance you book, which days you fly, and whether a sale is running when you search. The best fares on this corridor tend to appear 4 to 7 weeks out from departure during off-peak months, and 6 to 10 weeks out during summer.

Red-eye flights, departing New York between 9pm and midnight for early-morning arrivals in LA, consistently price below daytime departures on this route. If you can sleep on a plane and do not mind arriving before 7am, the red-eye saves both money and a hotel night. Daytime departures command a premium for the convenience of a normal schedule.

Spirit's contraction in late 2024 and 2025 removed a key price anchor from this corridor, and fares have generally run slightly higher than the 2023-2024 range as a result. The competitive floor has risen, though JetBlue's continued aggressive pricing on the transcon has partially offset that effect.

West Coast Regional Flights to LA

Flying between Seattle, Portland, San Francisco, and Los Angeles is often cheaper and faster than the alternatives, and the frequency of service on these routes is extraordinary. Seattle-LAX and Portland-LAX each see dozens of departures per day from Alaska, Southwest, United, and Delta, creating a competitive environment that keeps fares low. During non-peak periods, same-week flights on these routes can be found for $60 to $100 round trip.

San Francisco to LA is an anomaly in US aviation. The route is so short, at roughly 340 miles, and so heavily served that it functions almost like a commuter shuttle. Fares under $80 round trip are common outside of holiday and summer periods, and the flight itself takes under an hour. The main competition on this corridor is the Amtrak Pacific Surfliner for travelers comfortable with a train journey, but for pure speed the flight wins.

Sacramento, Fresno, and other Central Valley markets also connect to LA with regular service from Southwest and United, and fares from these smaller airports can be even lower than Bay Area to LA pricing. If you live near a smaller California airport, it is worth checking direct service to LAX or BUR before driving to a major hub.

How Far in Advance to Book Flights to LA

For domestic travel to LA, the booking sweet spot falls between 3 and 6 weeks before departure for most non-holiday periods. This timing captures fares after airlines have adjusted initial pricing based on early demand signals, but before scarcity pricing kicks in as seats fill. Booking more than 3 months out on domestic routes rarely saves money and often costs more, as airlines have not yet deployed discounted fare classes.

Holiday periods require a different approach. For Thanksgiving week, book by early October at the latest. For Christmas and New Year, September and October are not too early. Demand for LA during these windows is intense, particularly from East Coast markets, and the best fares disappear well before the conventional "book early" advice would suggest.

Summer travel to LA should be booked 6 to 10 weeks ahead, particularly for June and July departures. The transcontinental routes fill early during summer, and waiting until 2 or 3 weeks out often means paying a significant premium. April and May are good months to lock in summer LA fares before inventory tightens.

Days of the Week and Times of Day

Tuesdays and Wednesdays are consistently the cheapest days to fly to LA across most route types. Business and leisure demand both concentrate on Mondays and Fridays for work-adjacent travel, and on Thursdays through Sundays for pure leisure. The midweek trough creates meaningful pricing differences, often $30 to $70 lower per round trip compared to peak days on the same route.

Friday and Sunday departures carry the highest premiums on most LA routes. Sunday afternoons from LAX heading east are among the most consistently expensive departure windows in US domestic aviation, driven by leisure travelers returning after weekend trips and business travelers heading back for Monday meetings. If you can shift a Sunday departure to Saturday or Monday, you frequently find a better price.

Early morning flights, departing before 7am, and late-night departures, after 9pm, generally price below the midday and early evening windows. The red-eye transcons are the clearest expression of this principle, but even on shorter routes, the 6am departure often costs less than the 10am on the same aircraft type and route. The trade-off is convenience, and only you can decide whether the savings justify the schedule.

Use Farefinda to Find the Best LAX Fares

With four airports serving the LA area and prices varying significantly by departure day, booking window, and airline, monitoring fares manually across all the variables is impractical. Farefinda lets you search across multiple LA-area airports simultaneously and set fare alerts for your specific route. When a price drops on your origin-to-LA corridor, you get notified rather than having to check manually every few days.

The most effective approach: search for fares to LAX and BUR (or whichever alternate airport is most useful for your destination), set alerts on both routes, and monitor for a few weeks before committing to a date. The price differences between airports on the same routes can be surprising, and the few minutes of setup time often translates to meaningful savings.

Frequently Asked Questions

What is the cheapest month to fly to Los Angeles?

January and February are historically the cheapest months to fly to LA. The post-holiday demand drop pushes airlines to discount heavily, and transcontinental fares from New York and other East Coast cities frequently fall to $150 to $200 round trip during these months. September and October are the next-best value window, combining low crowds with the city's finest weather.

Is LAX always cheaper than Burbank or Long Beach?

Not at all. On routes from the Pacific Northwest, Bay Area, and Southwest markets where Southwest has strong Burbank or Long Beach service, those smaller airports regularly undercut LAX. Always search both LAX and BUR (and LGB if you are in the Long Beach corridor) before booking. The fare difference can be $40 to $80 on some routes.

How far ahead should I book flights to LA?

For most domestic routes, the sweet spot is 3 to 6 weeks before departure. For holiday periods like Thanksgiving and Christmas, book 8 to 12 weeks ahead. For summer travel, aim for 6 to 10 weeks out to secure inventory before peak demand fully reprices available seats.

Which airline is best for cheap flights to LA from New York?

JetBlue and American compete aggressively on the transcon and frequently offer the best economy fares. JetBlue in particular runs promotional fares on JFK-LAX that can undercut legacy carriers significantly. Always compare Southwest (if flying JFK-BUR or similar) alongside the legacy carriers for the full picture.

Is flying to LAX or Ontario cheaper from the Midwest?

Ontario (ONT) is worth checking on routes from Chicago, Denver, Dallas, and other Midwest or Southwest hubs, particularly on Southwest. Ontario fares can run $30 to $60 lower on certain routes, and if your final destination is the Inland Empire or you are renting a car, the ground transport math works in Ontario's favor.
