When planning your travel, one of the key considerations is how much luggage you can bring and how much it will cost. Fortunately for travelers flying with Southwest Airlines Checked Baggage Policy is among the most generous in the U.S. airline industry. Whether you're a frequent flyer or preparing for your first trip, understanding the details of Southwest Airlines' checked baggage policy can help you pack smarter and avoid unnecessary fees.
Southwest Airlines stands out in the airline industry for offering two free checked bags per passenger. This applies to all travelers, regardless of fare type, and it’s one of the most appealing aspects of flying with Southwest. While many other airlines charge for even the first checked bag, Southwest’s policy can result in significant savings—especially for families or travelers with lots of luggage.
However, this generous allowance does come with some guidelines. Each of the two checked bags must meet the following criteria:
If your bag exceeds these limits, you may still check it, but you'll be charged an oversize or overweight baggage fee.
If you’re packing heavy or carrying bulky items, it's important to know Southwest’s fees for overweight and oversized bags:
Bags over 100 pounds or 80 linear inches will not be accepted as checked baggage. In those cases, travelers will need to use Southwest’s cargo service.
Southwest Airlines also has specific rules for checking in special items such as sports equipment, musical instruments, baby gear, and mobility aids. In many cases, these items can be checked without counting toward your two-bag limit or without an additional fee—depending on size and weight.
For example:
Checking bags with Southwest is simple. You can do so at the airport ticket counter, curbside (at participating airports), or at a self-service kiosk. Bags must be checked at least 45 minutes before scheduled departure for domestic flights and at least 60 minutes prior for international flights.
