What is the Southwest new Baggage Policy?

The Southwest Airlines baggage policy remains one of the most passenger-friendly in the US! Many airlines now charge for almost everything. But Southwest still allows every passenger 2 free checked bags. This is a quick breakdown:

• Two free checked bags: Size & weight limits apply (up to 50 lbs & 62 linear inches per bag).
• One carry-on bag: It could be a small suitcase/duffel bag. It must fit in the overhead bin.
• One personal item: Think backpack, purse, laptop bag or briefcase. This has to go under the seat in front of you.

So yes, you can bring a backpack & a carry-on without paying extra! Just make sure both meet size rules.

Southwest does not charge for checked baggage unless you exceed the weight or size limits. Oversized or overweight bags will face extra fees.

How many bags can you take on Southwest Airlines for free?

The Southwest baggage policy is straightforward:

• Two checked bags for free

This alone sets them apart from most other US carriers.

• One carry-on bag

Overhead space gets tight on full flights, so early boarding can help secure bin space.

• One personal item (like your backpack)

This stays with you under the seat.

You don’t need to choose between a backpack and a carry-on. You’re allowed both. Just remember that if your backpack is large & won’t fit under the seat, reconsider. Southwest may ask you to check it at the gate.

For flyers with sporting equipment, musical instruments, or special luggage: Extra allowances or charges may apply. Check their official site for specialty item rules.

What is not allowed in a carry-on bag in Southwest?

The Southwest Airlines carry on policy follows TSA guidelines for restricted items. Some things simply can’t go in your carry-on or personal item.

Here’s what you’ll need to leave out:

• Liquids over 3.4 ounces (100 ml)

All liquids, gels, & aerosols has to fit in one quart-size plastic bag.

• Sharp objects

Knives, scissors with blades over 4 inches, and tools like screwdrivers or hammers aren’t allowed.

• Sporting equipment

Baseball bats, hockey sticks, and golf clubs can’t go as carry-ons. They need to be checked.

• Firearms and ammunition

These are allowed in checked baggage if packed following airline and TSA rules but never in carry-on.

• Flammable items

Lighter fluid, fireworks, & similar items are banned.

If in doubt, check TSA’s “What Can I Bring?” page before packing. And for items like laptops, tablets, or cameras: Yes, you can bring them. But you’ll need to take them out at security for screening.

How much are Southwest baggage fees?

This is where Southwest really wins with travelers. Southwest baggage fees for regular checked bags? Zero dollars for the first two bags.

However, there are fees for special situations:

• Overweight bags (51-100 lbs): Around $100 per bag, each way.
• Oversized bags (more than 62 inches combined size): Another $100 per bag.
• Extra bags (beyond your two free ones): Roughly $75 for each additional bag.

Here’s a simple fee snapshot:

Also, if you’re carrying sports equipment or large musical instruments, different fees may apply.

One thing to note—Southwest doesn’t charge change fees or cancellation fees on flights, which adds even more value when compared with airlines that charge for nearly everything.
