Cheap Flights To California: Best Strategies for 2026

The short answer isthat you can find cheap flights to California for as little as $100-$150 one-way if you book smart, but prices fluctuate wildly based on timing, airline, and how far in advance you book. The cheapest months to fly are January and February, when demand drops after the holidays and before spring break, with average round-trip prices around $250 for domestic routes.

Book at least 21 days in advance for the best deals—data from Google Flights shows that flights booked 21-30 days ahead are 15% cheaper than those booked last-minute. For example, a flight from Chicago to San Francisco in January typically averages $220, while the same route booked on the same day in February could cost $350 or more. Airlines like Southwest and Spirit often offer the lowest base fares, but always check for baggage fees, which can add $30 or more per trip.

Another key tip is to consider flying into secondary airports. For instance, flying into Oakland (OAK) instead of San Francisco (SFO) can save you $50-$75 on a round-trip ticket, especially during off-peak times. Similarly, flying into Long Beach (LGB) instead of Los Angeles (LAX) can cut costs by up to 20% for routes from the Midwest. These airports are well-connected to major cities via shuttles and public transit, so the added travel time to your final destination is usually minimal.

A common misconception is that booking flights on a Tuesday or Wednesday guarantees the cheapest fares. While some airlines do adjust prices mid-week, the most reliable strategy is to use price alerts on platforms like Google Flights or Kayak and monitor prices for at least two weeks before booking. For example, a trip from New York to Los Angeles in March saw a 25% price drop when a user set a price alert, whereas booking on a random day without tracking could have cost $100 more.

Don’t forget to factor in the cost of transportation from the airport to your hotel, especially if you’re staying in a city center. For instance, a ride from Oakland to downtown San Francisco costs about $25, while a bus or shuttle might cost $5-$10. To avoid surprise costs, use find cheap flights with filters for "airport transfers included" or check if your hotel offers free shuttle service.

One mistake travelers often make is assuming that budget airlines are always the cheapest. While Spirit and Frontier do offer low base fares, their add-on fees for checked bags, seat selection, and even carry-on luggage can quickly inflate the total cost. For example, a $50 Spirit flight from Dallas to Los Angeles can cost $120 once you add a $30 checked bag and $15 for a preferred seat. Always calculate the total price before booking.

If you’re planning a trip this winter, consider booking your flight for a Tuesday or Wednesday morning, as flights on those days tend to be 10% cheaper than weekend flights. For instance, a flight from Denver to San Diego on a Tuesday morning in February averages $180, while the same route on a Saturday could cost $250. This small adjustment can save you $70 on a round-trip ticket.

Finally, the best recommendation is to combine a flight with a hotel stay through a package deal. Sites like Expedia or Kayak often bundle flights and hotels for 15-20% less than booking separately. For example, a January trip to Los Angeles with a hotel in Santa Monica can cost $450 total for a two-night stay, including a round-trip flight from Chicago, whereas booking separately would run $550. Always check for package deals before finalizing your booking.
