Southwest Airlines is one of the most popular carriers in the U.S., known for two free checked bags with every fare, no change fees, and a friendly no-frills experience across its large domestic and near-international network. Operating without assigned seats, Southwest's open boarding system rewards early check-in. FaresMatch advisors compare Southwest fares with other airlines so you can see the full value — especially when checking bags makes Southwest's slightly higher base fare a better total deal.

Tips for booking cheap Southwest flights
Every Southwest fare includes two free checked bags — saving $35–$60+ per bag each way compared to most other carriers. If you're checking bags, Southwest's base fare is often the lowest total price even if it looks higher than an ultra-low-cost carrier's advertised rate.
Southwest doesn't charge fees for changes or cancellations. Cancelled tickets receive a credit valid for 12 months (or a refund for refundable fares). This makes Southwest a low-risk booking if your travel dates might shift.
Southwest uses open boarding groups (A, B, C). Checking in exactly 24 hours before departure improves your boarding position and your ability to choose a better seat. Early Bird Check-In (paid) automatically checks you in 36 hours before departure.
Southwest's Wanna Get Away and Wanna Get Away+ fares are the lowest tiers and regularly feature sale prices on popular routes. Checking early in the week often reveals newly dropped prices.
Frequently asked questions
Does Southwest have assigned seats?
No — Southwest uses open seating. Passengers are assigned a boarding group (A, B, or C) and a position number based on check-in time. You choose any available seat when you board. There are no seat selection fees, but earlier boarding positions give more choice.
Are Southwest flights on Google Flights?
No — Southwest does not list its flights on Google Flights, Kayak, Expedia, or most third-party booking platforms. You can book Southwest directly on Southwest.com or through FaresMatch, where our advisors can compare Southwest fares alongside other carriers.
What is Southwest's Rapid Rewards program?
Rapid Rewards is Southwest's free frequent flyer program. Members earn points on Southwest flights and with partner spending, redeemable for flights with no blackout dates. The Southwest Companion Pass — earned by accumulating 135,000 qualifying points in a calendar year — is one of the best deals in travel loyalty, allowing one person to fly free on every Southwest flight you take for the rest of that year and the entire following year.
Can I cancel a Southwest flight for free?
Yes — Southwest does not charge change or cancellation fees. Wanna Get Away fares cancelled in advance earn a travel credit valid for 12 months from the date of the original booking. Anytime and Business Select fares are fully refundable to the original payment method.
