Southwest Baggage Fees (2026)
On most Southwest fares your carry-on is free and a checked bag costs $45 for the first and $55 for the second, each way.
Quick answer
Since May 28, 2025, most fares pay for checked bags; Bags Fly Free® no longer applies to them. Carry-on and personal item remain free on all fares. U.S. Mainland checked bags (booked and ticketed, or changed, on or after April 9, 2026): Basic, Choice and Choice Preferred $45 for the 1st bag and $55 for the 2nd; Choice Extra 2 free; 3rd bag and later $150 each. Standard checked bag up to 50 lb and 62 in (length plus width plus height); no prepaid discount published. Free checked paths: Choice Extra, A-List Preferred (2), A-List and Rapid Rewards® credit card (1st bag), active-duty military (2), Getaways.
What you'll actually pay
Prices are for Basic, Choice and Choice Preferred tickets on the U.S. mainland, booked or changed on or after April 9, 2026. Southwest charges each way, so a round trip pays twice.
Solo traveler, carry-on only: $0. Your carry-on and personal item are free both ways.
Round trip with 1 checked bag: $45 out plus $45 back makes $90.
Family of four, 2 checked bags, round trip: if two people each check one bag, that's 2 bags at $45, or $90 each way, so $180 for the trip. If one person checks both bags, it's $45 plus $55, or $100 each way, so $200. Splitting the bags between two travelers saves $20.

Gotchas
- Out-of-date “Bags Fly Free®” pages still show up in search. Since May 28, 2025, checked-bag fees have applied to most fares.
- Change date catch: voluntarily changing a ticket bought before April 9, 2026 can move you onto the $45 and $55 table.
- Southwest does not publish a $5 online prepaid discount like American’s.
- A-List 2nd bag is still $35 for tickets booked on or after April 9, 2026; it was not raised to $55.
- Oversize and overweight: one $200 fee plus the standard fee (up to 100 lb); you don’t pay $200 twice.
- Bags over 80 in (other than sports equipment or instruments) or over 100 lb are generally not accepted as standard.
- Hawaii interisland uses a different schedule; don’t apply mainland $45 and $55 prices there.
Avoid fees
- Fly with a carry-on and personal item only when possible.
- Book Choice Extra if you need two free checked bags.
- Having your Rapid Rewards number and A-List status on the reservation, and paying with an eligible co-brand card when it covers the 1st bag, can save the fee.
- Stay within 50 lb and 62 in to avoid overweight and oversize add-ons.
- Use military or Getaways benefits when eligible.
- An itinerary change that re-tickets your trip can move it onto the newer fee table.
