The End of an Era: Southwest’s Baggage Revolution

After more than five decades of “Bags Fly Free,” Southwest Airlines shook the travel world when they announced the end of their legendary policy. Starting May 28, 2025, Southwest introduced checked bag fees of $35 for the first bag and $45 for the second bag for most passengers. But here’s the thing, you can still game the system if you know the rules.

I’ve been tracking Southwest’s baggage evolution since they first hinted at changes, and let me tell you, this isn’t just another airline fee grab. It’s a complete strategic overhaul that puts Southwest in line with industry standards while still offering some unique perks that savvy travelers can exploit.

What’s Actually Changed in 2025?

Let’s cut through the noise and talk about what really matters to your wallet.

The New Southwest Checked Baggage Fees

For flights booked on or after May 28, 2025:

• First checked bag: $35
• Second checked bag: $45

For flights booked before May 28, 2025:

• You still get two free checked bags (grandfathered in)

The fees apply to Basic, Choice, and Choice Preferred fares, but here’s where it gets interesting – there are still plenty of ways to sidestep these charges entirely.

Who Still Gets Free Bags?

Two Free Checked Bags:

• Rapid Rewards A-List Preferred members
• Choice Extra fare passengers
• Business Select travelers
• Active-duty military customers with valid ID

One Free Checked Bag:

• Rapid Rewards A-List members
• Rapid Rewards Credit Cardmembers (plus up to 8 companions on the same reservation)

Southwest Carry-On Policy: Still Your Best Friend

Here’s some good news – Southwest’s carry-on policy remains unchanged, with no fees for carry-on luggage. Every passenger gets one carry-on bag and one personal item absolutely free.

Southwest Carry-On Size Limits

Carry-On Bag:

• Maximum dimensions: 24 x 16 x 10 inches (including wheels and handles)
• No weight restrictions (but you must be able to lift it yourself)
• Must fit in overhead compartment

Personal Item:

• Maximum dimensions: 18.5 x 8.5 x 13.5 inches
• Must fit under the seat in front of you
• Examples: purse, laptop bag, small backpack

Pro Tip: Southwest’s Generous Carry-On Policy

Many frequent Southwest travelers report that the airline tends to be more lenient with carry-on enforcement compared to other carriers, though they’ll still enforce the rules on busy flights when overhead space is limited.

Southwest Checked Baggage Rules and Weight Limits

Standard Checked Bag Requirements

Size and Weight Limits:

• Maximum weight: 50 pounds per bag
• Maximum linear dimensions: 62 inches (length + width + height)
• Up to 20 checked bags per passenger per flight

Overweight and Oversized Bag Fees

The fees get steep if you exceed the limits:

Sports Equipment and Special Items

Southwest maintains relatively friendly policies for sports gear:

• Sporting equipment includes surfboards, bicycles, kayaks, and golf bags
• Standard checked bag fees apply
• Some items like surfboards between Hawaiian islands can substitute for one checked bag
• Musical instruments can travel as carry-ons if they fit the size requirements

Military and Family Perks

Military Benefits:

• Active-duty military personnel with valid ID receive unlimited free checked bags (up to 100 lbs and 80 inches each)

Family Travel:

• Strollers and car seats check free
• Child restraint systems don’t count toward baggage allowance

How to Avoid Southwest Baggage Fees in 2025

Strategy 1: Status and Credit Cards

The Southwest Rapid Rewards credit cards are suddenly much more valuable. Cardmembers get one free checked bag for themselves plus up to 8 companions on the same reservation – that’s a game-changer for family travel.

Strategy 2: Fare Class Upgrades

If you upgrade to Choice Extra before check-in, you’ll be eligible for two free checked bags. Sometimes the upgrade cost is less than paying for two bags separately.

Strategy 3: Pack Smart

With generous carry-on allowances, many travelers can still avoid checked bag fees entirely. The 24x16x10 inch limit is more generous than most airlines.

Southwest International Baggage Policy

Certain international destinations have baggage embargos during peak seasons:

Year-Round Restrictions:

• Cuba (HAV) – limited to 2 standard bags only

Seasonal Restrictions:

• Bahamas, Belize, Costa Rica, Jamaica: November 15 – January 15
• Jamaica (MBJ): August 15 – September 15

Lost and Delayed Baggage Claims

Southwest maintains their customer-friendly approach to baggage issues. If your bag is lost or delayed, you can file claims through their website or customer service. The airline typically provides reasonable compensation for delayed bags and necessities.

The Bottom Line

Southwest’s baggage policy shift marks the end of an era, but it’s not necessarily bad news for savvy travelers. The $35/$45 fee structure is competitive with other major airlines, and plenty of workarounds exist.

The key is understanding the new landscape and planning accordingly. Whether that means investing in a Southwest credit card, upgrading your fare class, or simply packing more efficiently, there are still ways to make Southwest work for your budget.

Remember, the travel game is always evolving. While we mourn the loss of “Bags Fly Free,” the smart money is on adapting to the new rules and finding the loopholes that still exist. Southwest may have changed their baggage policy, but they haven’t lost their soul – you just need to know how to work with it.
