Few airline policies are as widely discussed—or as widely misunderstood—as Southwest Airlines’ baggage allowance. While most U.S. airlines have steadily increased baggage fees over the past decade, Southwest continues to advertise a simple, traveler-friendly promise:
“Two bags fly free®.”
But do you really get two free checked bags on Southwest? Are there weight limits, size restrictions, or hidden catches? And how does Southwest’s baggage policy compare to competitors like Delta, United, and American Airlines in 2025?
This in-depth guide answers those questions with data-backed explanations, real-world examples, and practical tips—so you know exactly what to expect at the airport.
Why Southwest’s Baggage Policy Matters More Than Ever
According to Consumer Reports, baggage fees are among the top three consumer complaints in air travel, particularly on domestic U.S. routes. Many airlines charge:
- $30–$40 for the first checked bag
- $40–$50 for the second checked bag
- Even more for overweight or oversized luggage
For a family of four, baggage fees alone can exceed $300 round-trip on legacy carriers.
Southwest’s baggage allowance directly addresses this pain point—making it a key reason travelers continue to choose the airline despite its lack of assigned seating or first-class cabins.
The Short Answer: Yes, You Really Get 2 Free Checked Bags
Yes—Southwest Airlines allows every ticketed passenger to check two bags for free, with no elite status, co-branded credit card, or fare upgrade required.
This policy applies to:
- Wanna Get Away® fares
- Wanna Get Away Plus® fares
- Anytime fares
- Business Select® fares
There is no difference in baggage allowance based on fare type.

Traveling with Children: What Parents Should Know
Parents traveling with infants and toddlers benefit significantly from Southwest’s baggage rules.
Family-Friendly Highlights
- Car seats and strollers check free
- No fees for gate-checked strollers

Step-by-Step: How to Check Bags on Southwest
Before You Go
- Weigh your bags at home (aim for under 48 lbs)
- Measure dimensions if using large suitcases
- Attach name and contact tags
At the Airport
- Use self-service kiosks or counter check-in
- Print bag tags
- Drop bags at the designated counter
Pro Tip from Frequent Flyers
Experienced travelers recommend leaving 2–3 lbs of buffer to avoid overweight fees caused by scale differences.
Does Southwest Ever Change This Policy?
Southwest’s “Bags Fly Free®” policy is deeply embedded in its brand identity.
According to Harvard Business Review, Southwest uses baggage inclusion as a strategic differentiator, not a promotional tactic. While airline policies can change, eliminating free bags would require a major shift in Southwest’s business model.
Based on publicly available information, there is no confirmed data indicating Southwest plans to end free checked bags.
Hidden Gotchas (What Travelers Miss)
Even generous policies have fine print.
Common Mistakes
- Assuming overweight fees are waived (they are not)
- Bringing bags over 80 inches (not accepted)
- Forgetting lithium battery rules for checked bags
Always check the most current baggage guidelines before travel.
Is Southwest’s Baggage Policy Good for International Travel?
Southwest primarily operates within:
- The U.S.
- Mexico
- Central America
- The Caribbean
The two free checked bags policy still applies on international routes, though customs regulations may affect what you can pack.
Refer to official government travel advisories (such as gov.uk or U.S. CBP guidance) for prohibited items.
