When it comes to air travel, understanding baggage policies is essential for avoiding unnecessary costs and stress at the airport. Southwest Airlines is known for its generous baggage policy, which includes two free checked bags for each passenger. However, there are still some important details to keep in mind about checked bag sizes, fees for extra luggage, and other rules.

This guide covers everything you need to know about Southwest checked bags, helping you plan your trip with confidence and ease.

Southwest Checked Bag Fees (How Much Will You Pay?)

Southwest Airlines offers two free checked bags per passenger on all domestic and international flights. This generous allowance makes it a standout choice for budget-conscious travelers.

However, if you exceed the two-bag limit or have oversized items, you will face additional fees. Here's a breakdown of potential charges:

  • First two checked bags: Free

  • Third checked bag and beyond: $75 per bag

  • Oversized bags: Bags exceeding 62 inches (length + width + height) will incur a $75 fee per item.

  • Overweight bags: Bags weighing more than 50 pounds but under 100 pounds will incur a $75 fee. Bags weighing over 100 pounds are not allowed.

These fees apply to both domestic and international flights.

Southwest Checked Bag Size Limits (What Are the Dimensions?)

To avoid oversized baggage fees, it’s important to know the size restrictions for Southwest checked bags. Here are the size limits:

  • Maximum weight per checked bag: 50 pounds (22.6 kg)

  • Maximum dimensions: 62 inches (157 cm) total (length + width + height)

If your checked bag exceeds the size limit, you’ll face a fee of $75 for each oversized item. Remember that some items may require special handling or arrangements, such as golf clubs, skis, or musical instruments.

Additional Southwest Checked Bag Rules (What You Should Know)

While Southwest is known for its friendly and flexible baggage policies, there are a few other things to keep in mind when preparing your checked bags:

  • No limit on carry-ons: Southwest allows one personal item (e.g., backpack, purse, laptop bag) and one carry-on bag per passenger. The carry-on must fit in the overhead bin and adhere to size guidelines.

  • Special items: Some items, like sporting equipment, musical instruments, or strollers, may require additional fees or special handling. Always check Southwest's website for specific guidelines regarding special items.

  • Checking bags at the gate: If you arrive late at the gate or your carry-on is too large to fit in the overhead bin, Southwest offers a gate check service for your carry-on luggage.

Why Southwest's Baggage Policy is a Game Changer

Southwest’s checked baggage policy is one of the most generous in the industry. While many airlines charge hefty fees for checked bags, two free checked bags per passenger give Southwest customers a significant advantage. This can make a real difference for travelers looking to avoid hidden fees and manage luggage costs efficiently.

This benefit, coupled with the affordable base fares, makes Southwest a top contender for both budget-conscious flyers and those looking for a hassle-free airport experience.
