Southwest Airlines Baggage Fees Start in 2025: What Travelers Need to Know

Southwest Airlines Ends Free Checked Bags: What Travelers Need to Know in 2025

For decades, Southwest Airlines distinguished itself in the crowded airline market by foregoing checked bag fees. Beginning May 28, 2025, this beloved hallmark is coming to an end. In response to ongoing financial pressures and changing industry standards, the airline is launching a range of sweeping policy updates. This guide breaks down all the critical details, from new baggage charges to overhauled fare structures and forthcoming changes to seat assignments—helping you plan your next journey with confidence.

Summary of Major Changes Effective May 28, 2025

• Checked baggage fees introduced for most passengers
• New “Basic” fare class with the lowest prices and most restrictions
• Assigned and premium seating to roll out later in 2025
• Flight credits will now expire, with limits based on fare type
• Updated rules for portable chargers and carry-on usage

New Checked Baggage Fees: Key Facts

As of May 28, 2025, Southwest Airlines will no longer offer two free checked bags to all customers. Instead, a tiered fee structure is taking effect for all new reservations and tickets purchased from this date onward.

Note: Limits: 20 checked bags per passenger; oversize and overweight fees cannot be combined beyond $200 per bag.

Grandfathered Baggage Policy: What About Bookings Made Before May 28?

If your reservation was booked and ticketed, or voluntarily changed, before May 28, 2025, you can still check your first and second bag for free on those flights. All subsequent reservations will fall under the new fee structure.

Are There Still Any Free Bag Allowances?

• Rapid Rewards Credit Cardmembers: First checked bag free for the cardholder and up to eight travelers on the same reservation.
• Choice Extra fares, A-List Preferred members, and Getaways by Southwest Customers: Two free checked bags per traveler.
• Active duty military and certain media personnel: Continue to receive waived fees; see airline for details.

Changes to Carry-On Allowance: What Remains the Same?

Southwest continues to offer one standard carry-on bag (up to 10 x 16 x 24 inches) and one personal item (such as a purse, briefcase, or laptop bag) for free to each passenger. However, there are new operational protocols regarding certain electronics in the cabin.

Portable Charger Device Policy Updated

Passengers must now keep all portable charging devices (such as power banks) visible during use while on the aircraft. Charging a device stored inside a bag or overhead compartment is prohibited. This aligns with airport safety guidance and ensures in-flight fire risks are minimized.
Southwest spokesperson: “Using portable charging devices while stored in a bag or overhead bin will no longer be permitted.”

New Fare Structure: The Introduction of “Basic” Fares

May 28 also marks the debut of Southwest’s new “Basic” fare—designed for budget-conscious travelers willing to forgo certain comforts and flexibility. This fare replaces the longstanding “Wanna Get Away” option.

• Lowest base price among available fares
• Most restrictions (including bag fees, no same-day flight changes, and limited flight credits)
• Does not include any free checked bags (unlike some higher fare tiers)

Other fare types—such as “Choice,” “Choice Preferred,” and “Choice Extra”—retain more benefits, including checked bag allowances, Rapid Rewards points accrual, and additional flexibility for changes or cancellations.

Upcoming: Assigned and Premium Seating

Since its inception, Southwest has maintained an open seating policy. Starting in the second half of 2025, the airline plans to offer assigned seating in select fare classes, with full implementation expected in early 2026.

• Standard and Preferred Seats: Standard assigned seats at no extra cost; preferred seats (closer to the front, exit row, etc.) available for a premium.
• Extra Legroom: Some seats will offer additional legroom for an added charge.

Travelers who prefer Southwest’s traditional open seating will retain some access to that option, but those seeking certainty or more comfort can pay for assigned or premium seating.

Flight Credits: Expiration Policy Changes

Previously, flight credits earned from cancellations or downgrades on Southwest flights did not expire. Under the new terms for credits issued on or after May 28, 2025:

• Expiration Date Introduced: Flight credits now expire either one year or six months from issue, depending on the fare type.
• Existing Credits Protection: Credits created on or before May 27, 2025, will not expire.

Be sure to review each fare’s terms before booking to make the most of your credits and avoid loss of value.

Additional Fees for Overweight, Oversized, and Special Baggage

Southwest’s new baggage policies also clarify charges for items that exceed standard size and weight:

• Overweight Bags (51-70lbs): $100 per bag
• Overweight Bags (71-100lbs): $200 per bag
• Oversized Bags (over 62”, up to 80”): $200 per bag
• Sporting Equipment: Typically $75 per item; see airline for specific item policies
• Large Media Camera Equipment: $75 per item, with some exemptions

There is a limit of 20 checked bags per customer per flight, inclusive of both standard and excess baggage. If a piece is both oversized and overweight, only a single $200 fee applies, provided it remains under 100 lbs.

Who Remains Exempt? Special Cases and Allowances

• Active U.S. military personnel: Remain exempt from checked baggage fees
• Certain media professionals: Dependent on approved media status and equipment types
• Rapid Rewards Credit Cardmembers: First checked bag is free for the cardholder and up to eight additional passengers on the same booking
• Choice Extra and Getaways by Southwest: Still receive two free checked bags

Review all exceptions and book accordingly if you believe you qualify for a waiver.
