Southwest® Baggage Fees

For decades, Southwest Airlines stood out among U.S. carriers by letting travelers check up to two bags free of charge.

However, as of May 28, 2025, Southwest introduced checked baggage fees for most passengers on many fare types.

Unless you qualify through specific fare bundles, elite status, or credit card benefits, you’ll now pay for checked luggage, just like with other major airlines.

Southwest may have been the last airline holding out on baggage fees, but that era has officially taken off.

When Southwest Airlines charges checked bag fees

Southwest’s checked bag fees generally apply to flights booked on or after May 28, 2025, for most standard fare types. If you don’t have an eligible fare bundle or baggage waiver through Rapid Rewards status or a Southwest credit card, checked luggage will typically cost extra.

Keep in mind that these fees are usually charged per direction, meaning you’ll pay once for your departing flight and again on the way home. In other words, your suitcase may be going on a roundtrip vacation of its own.

Below, we’ll break down Southwest Airlines’ updated baggage fees, policies, and restrictions, and show how you can skip the check-in counter drama (and surprise charges) by shipping your luggage with LugLess instead (available for shipments within the U.S. and intra-Canada).

Southwest Checked Bag $35–$45+ (per bag) Airport lines + baggage claim Airport

How to avoid Southwest baggage fees

Here are some tips to reduce or eliminate baggage fees:

  • Pack only your carry-on + personal item to avoid checked bag charges entirely.
  • Book an eligible fare (like Business Select or Choice Extra) that includes free checked bags.
  • Earn Rapid Rewards elite status to unlock free checked bags. 
  • Use a Southwest co-branded credit card that offers at least one free checked bag benefit.
  • Consider shipping your luggage ahead with LugLess for door-to-door delivery.

Southwest Airlines checked baggage policy

Checked bags on Southwest are now usually paid add-ons unless you qualify for a waiver.

That means many travelers who used to check bags without thinking twice may now see extra charges added at checkout—or worse, at the airport counter.

Southwest Airlines checked baggage fees

Southwest baggage fees do not apply to the first two bags weighing up to 50lbs and measuring 62″ (L+W+H) or less.

Checked bags on Southwest are now usually paid add-ons unless you qualify for a waiver.

Southwest checked bag size & weight limits

  • Maximum size: 62 linear inches (length + width + height) 
  • Maximum weight: Up to 50 lbs per checked bag

If your bag exceeds these limits, additional overweight and oversized fees will apply. 

Southwest Airlines excess baggage fees

Checking excess baggage on Southwest Airlines costs $75 per bag for your third or more checked bag.

Southwest Airlines overweight baggage fees

  • Bags weighing 51–70 lbs may incur an extra charge in addition to the checked bag fee.

Bags over 70 lbs may not be accepted.

Southwest Airlines oversized baggage fees

  • Bags that exceed 62 linear inches may incur oversize fees on top of the checked bag fee. 

These overweight and oversize charges are in addition to checked bag fees and must be paid whether or not the bag is within the count of checked pieces.

Southwest Airlines carry-on baggage rules

Southwest still offers most passengers:

  • 1 carry-on bag (free)
  • 1 personal item (free)

This is good news for light packers, and bad news for anyone who treats vacation packing like a competitive sport.

Southwest Airlines carry-on size limits

Carry-on bags must fit in the overhead bin, while personal items must fit under the seat.

  • Carry-on max size: 24″ × 16″ × 10″
  • Personal item size: Must fit under the seat (common examples include purses, laptop bags, and backpacks)

Southwest does not impose a formal weight limit on carry-ons, but you should be able to lift them unassisted into the overhead compartment.

Southwest Airlines baggage fees for international flights

Southwest Airlines also operates international routes, and baggage policies are generally similar to domestic flights. However, international travelers should be aware that baggage handling rules may vary depending on airport procedures and destination requirements.

Since checked bag fees are often charged per direction, international travelers with multiple bags may see costs add up quickly, especially for roundtrip trips.

For travelers heading abroad with bulky luggage, shipping your bags ahead can often be a more convenient alternative.

Southwest Airlines special items 

(Sports Gear, Strollers, and More)

Many Southwest passengers travel with items that don’t fit neatly into a carry-on, such as sports equipment, baby gear, or musical instruments. Southwest may allow these items to be checked, but they can still be subject to oversize or overweight fees depending on their dimensions and weight.

Common special items travelers may bring include:

  • Golf clubs
  • Skis and snowboards
  • Surfboards
  • Car seats and strollers
  • Musical instruments

If you're traveling with bulky gear, shipping it ahead can help you avoid oversized baggage fees and the headache of dragging awkward items through the airport.

  • Rapid Rewards A-List Members: One free checked bag
  • Rapid Rewards Credit Cardmembers: One free checked bag (with account number attached at booking)
