Flying from Chicago to San Francisco is a popular route, whether for business or leisure, and finding low fares can significantly reduce the overall cost of your trip. But with so many airlines offering flights on this route, how do you know which one offers the best value? In this article, we’ll compare several airlines that provide low fares from Chicago to San Francisco, focusing on price, services, baggage policies, and overall value to help you make an informed choice.
1. Southwest Airlines: The King of Low Fares and Free Baggage
Southwest Airlines is a favorite among budget-conscious travelers, known for its transparent pricing and customer-friendly policies.
- Low Fares: Southwest frequently offers some of the lowest fares on the Chicago to San Francisco route, especially if you book during one of their frequent sales. Their “Wanna Get Away” fares are often the cheapest, but keep an eye out for their flash sales, where prices can drop even further.
- Free Baggage: One of Southwest’s biggest advantages is its baggage policy. Unlike many other airlines, Southwest allows two free checked bags per passenger, which can save you a significant amount of money, especially if you’re traveling with luggage.
- No Change Fees: Southwest doesn’t charge for changing your flight, which adds flexibility if your plans change. However, you’ll need to pay the difference in fare if the new flight is more expensive.
- In-Flight Experience: Southwest’s flights offer basic amenities like free snacks and non-alcoholic beverages, as well as free streaming entertainment on your device. While the seating is all economy and lacks assigned seats, their open seating policy allows you to choose your spot when you board.
Pros:
- Consistently low fares
- No baggage fees for two checked bags
- Flexible change policy
Cons:
- Open seating may not appeal to everyone
- Basic in-flight amenities
2. Spirit Airlines: Ultra-Low Fares with a Catch
Spirit Airlines is well-known for its ultra-low base fares, but these come with trade-offs in terms of fees and comfort.
- Low Fares: Spirit’s base fares are often the cheapest you’ll find on the Chicago to San Francisco route. They use an unbundled pricing model, which means you pay only for the flight, and everything else is extra. This can be great if you’re traveling light and don’t need any frills.
- Fees: Spirit is notorious for its additional fees. Carry-on and checked baggage fees are higher than those of most other airlines, and you’ll also pay for seat selection, in-flight refreshments, and even printing your boarding pass at the airport. These fees can add up quickly, so it’s essential to factor them in when comparing costs.
- In-Flight Experience: Spirit’s seats are basic, with less legroom and no reclining feature. In-flight entertainment is not provided, and even water costs extra, so be prepared for a no-frills experience.
Pros:
- Extremely low base fares
- Ideal for travelers with no baggage and no need for extras
Cons:
- High fees for baggage and other services
- Very basic in-flight experience
3. Frontier Airlines: Another Ultra-Low-Cost Option
Frontier Airlines is similar to Spirit in that it offers low base fares with a variety of add-ons, making it a competitive option for those seeking budget travel.
- Low Fares: Frontier’s fares are competitive with Spirit’s, often offering similar ultra-low-cost tickets. They frequently run promotions and discounts, so if you’re flexible with your travel dates, you can snag a great deal.
- Fees: Like Spirit, Frontier charges for almost everything beyond the base fare. Carry-on and checked baggage come with fees, and you’ll pay extra for seat selection, food, and beverages. However, their “The Works” bundle offers a way to save if you need multiple services, including a checked bag, carry-on, seat selection, and the ability to change your flight.
- In-Flight Experience: Frontier’s in-flight experience is similar to Spirit’s, with basic seating and no complimentary snacks or entertainment. However, their newer aircraft are more fuel-efficient, which might translate to a slightly more comfortable ride.
Pros:

- Baggage and Fees: United’s baggage fees are standard among legacy carriers, with fees for checked bags and optional seat upgrades. Their Basic Economy fare is the most affordable, but it comes with restrictions such as no overhead bin space and seat assignment at check-in. If you prefer more flexibility, their standard Economy fare might be worth the extra cost.
