Key Takeaways

  • Southwest Airlines allows 2 free checked bags per passenger, a standout feature among U.S. airlines, making it a budget-friendly option for travelers with luggage.
  • Additional bags or overweight or oversized items incur fees, with charges starting at $150 per bag for excess baggage.
  • Southwest does not allow you to prepay for luggage, which must be paid for at the airport.

Southwest Airlines has the single most clear-cut (and cheapest!) baggage policy of any airline. Thank You, Southwest!

Your first 2 checked bags are free with any fare, and the extra and excess baggage fees start at $100.

Southwest is the rare example of a budget airline where you definitely won’t get stuck with hidden baggage fees.

Southwest Carry-On Allowance

  • 1 personal item: Free
  • 1 standard carry-on bag: Free

Size Restrictions

  • Personal: 16.25 x 13.5 x 8.5 inches (41 x 34.3 x 22 centimeters)
  • Standard: 24 x 16 x 10 inches (60.9 x 40.6 x 25.4 centimeters)

Lap Infant Carry-On Policy

Stroller Check Policy

  • Southwest allows strollers and car seats to be checked at the curb, ticket counter, or gate free of charge.

Southwest Checked Baggage Allowance

All checked bags must adhere to a maximum weight of 50 pounds (23 kilograms) and maximum linear dimensions of 62 inches (158 centimeters).

Southwest is the only airline that provides 2 free checked bags for all fares:

  • First Bag: Free
  • Second Bag: Free
  • 3 or More Bags: $150
Hot Tip:

When talking about baggage allowances, many airlines refer to “maximum linear dimensions” or something similar. This is merely the number you get when you add the length, width, and depth of a piece of luggage. For example, if you have a suitcase that’s 26 inches long, 20 inches wide, and 16 inches deep, then its linear dimensions are 62 inches, or right at the maximum for many airlines.

Additional and Excess Baggage Fees

  • Overweight Fee: $150 per bag (51 to 70 pounds) or $200 per bag (71 to 100 pounds)
  • Oversized Fee: $200 per bag larger than 62 inches, up to 80 inches

Exclusions and Waivers

Military personnel traveling on active duty or permanent change of station orders are exempt from the 2-bag allowance and are not charged overweight or oversized fees, providing the bags do not exceed 100 pounds and 80 inches.

Some special sporting items fly free when substituted for one of the free bags (subject to certain restrictions). These items must not exceed 50 pounds or 62 inches. Otherwise, excess weight and size charges may apply.

  • Archery equipment
  • Baseball and softball equipment
  • Boogie and kneeboards
  • Bowling bags
  • Bicycles
    • Hard-sided bicycle box falling within the 62-inch and 50-pound limits
  • Fishing rod and tackle box
    • Limited to 91 inches in length, 3 inches in diameter
    • Counts as 1 item even if packed separately
  • Golf bag
    • Hard-sided golf bag
    • Excess size charges waived; excess weight charges may apply
  • Hockey and lacrosse sticks
    • Up to 2 bags can count as 1 item, even if packed separately
  • Knives, dress sabers, swords
    • Checked bags only
  • Parachutes
    • Carry-on or checked bag
    • May not be worn in flight

    • May be subject to a limited release of liability
  • Water ski equipment
    • Excess size charges waived; excess weight charges may apply

For other baggage fees related to special luggage (sporting equipment, musical instruments, etc.) please refer to Southwest Airlines’ policy.

Can I Prepay for Baggage?

Southwest Airlines does not let passengers prepay for luggage. This means passengers must pay at the ticketing counter at the airport.
