Travel should be exciting, not stressful, especially when it comes to packing. Understanding airline baggage policies before you head to the airport can save you time, money, and a lot of headaches. Southwest Airlines, known for its unique boarding process and generally generous policies, has specific rules regarding checked bags, carry-ons, and personal items. Let's break it down!

| How Many Suitcases Can I Take On Southwest Airlines |
Step 1: Let's Get Started! – Understanding the Basics
First things first, before we even talk numbers, let's address the most crucial aspect: your ticketed fare and Rapid Rewards status. As of May 28, 2025, Southwest has introduced changes to its checked baggage policy, meaning the good old "bags fly free" for everyone is no longer universal.
-
Have you booked your flight on or after May 28, 2025? If so, pay close attention, as the fee structure for checked bags may apply to you, depending on your fare type.
-
Do you have Southwest Rapid Rewards A-List Preferred status, A-List status, or a Southwest co-branded credit card? These can significantly impact your free baggage allowance.
-
Are you an active-duty military passenger with a valid ID? You're in luck, as you generally have a more generous allowance.
Take a moment to consider your specific situation. Knowing this will help you navigate the following steps more effectively.
Step 2: Cracking the Code – Checked Baggage Allowance
This is often where the most questions arise. Let's talk about the suitcases you want to check in.
Sub-heading 2.1: The Standard Allowance (New Policy)
For flights booked on or after May 28, 2025, the standard allowance for checked bags for most travelers is:
-
First Checked Bag: $35
-
Second Checked Bag: $45
Each of these checked bags must adhere to specific size and weight limits:
-
Maximum Weight: 50 pounds (23 kg) per bag.
-
Maximum Size: 62 linear inches (length + width + height) per bag. This means you add the length, width, and height of your suitcase, and the total shouldn't exceed 62 inches.
Sub-heading 2.2: Who Still Gets Bags Fly Free?
Tip: Reading in chunks improves focus.
While the universal "bags fly free" has changed, several groups still enjoy this benefit:
-
Business Select® Fare Holders: If you've purchased a Business Select® fare, you are entitled to two free checked bags.
-
Rapid Rewards A-List Preferred Members: Enjoy two free checked bags for yourself and up to eight additional passengers on the same reservation.
-
Rapid Rewards A-List Members: Receive one free checked bag for yourself and up to eight additional passengers on the same reservation.
-
Southwest Rapid Rewards Credit Card Holders: Depending on your specific card, you may receive one free checked bag. Always double-check your card benefits!
-
Active-Duty Military Passengers: Presenting a current, valid military ID exempts you from the two-piece baggage limit and excess, oversize, or overweight baggage charges, provided each bag does not exceed 100 pounds in weight and 80 inches in size (L+W+H). This is a fantastic benefit!
Sub-heading 2.3: Navigating Excess, Overweight, and Oversized Baggage Fees
Sometimes, despite our best efforts, our suitcases just don't conform. Here's what you can expect for bags that exceed the standard limits:
-
Third (or More) Checked Bag: If you need to check a third bag (or more) beyond your allowance, the charge is $150 per bag.
-
Overweight Baggage:
-
For bags weighing 51 to 70 pounds: $100
-
For bags weighing 71 to 100 pounds: $200
-
Note: Any item weighing more than 100 pounds generally must be shipped as Air Cargo and cannot be checked as baggage.
-
-
Oversized Baggage: For bags larger than 62 linear inches up to 80 linear inches: $200.
-
Combined Overweight & Oversized: If your bag is both overweight and oversized, you will typically be charged one combined fee, usually the higher of the two applicable fees. For example, a bag that is 70 lbs and 70 linear inches will incur a $200 charge.
Important Tip: Always measure and weigh your bags before you leave for the airport! Investing in a small luggage scale can save you a significant amount of money and stress.
Step 3: Lightening Your Load – Carry-on Baggage Allowance
Beyond your checked suitcases, you also get to bring items into the cabin with you. This is crucial for essentials, valuables, and anything you need during your flight.
Sub-heading 3.1: Your Carry-On Bag
Each ticketed passenger is allowed one carry-on bag.
-
Maximum Dimensions: 24 inches (L) x 16 inches (W) x 10 inches (H). This includes handles and wheels.
-
Weight Limit: Southwest does not specify a weight limit for carry-on bags. However, you must be able to lift it into and out of the overhead bin yourself without assistance. If you can't, it might be gate-checked.
Sub-heading 3.2: Your Personal Item
In addition to your carry-on bag, you are allowed one personal item. This item must fit under the seat in front of you.
-
Examples: A purse, briefcase, laptop bag, small backpack, camera bag, or a food container. Neck pillows and blankets generally don't count towards the limit.
-
Maximum Dimensions: Typically 18.5 inches (L) x 8.5 inches (W) x 13.5 inches (H).
-
Weight Limit: Similar to carry-ons, Southwest does not specify a weight limit for personal items, but it must fit under the seat in front of you.
Sub-heading 3.3: What Doesn't Count Towards Your Carry-On Limit?
Tip: Every word counts — don’t skip too much.
Southwest is quite accommodating with certain items that don't count against your one carry-on and one personal item limit:
 |
-
Outer garments (coats, wraps)
-
Umbrellas or walking canes
-
Food for consumption during the flight (in disposable packaging)
-
Assistive/mobility devices (wheelchairs, crutches, walkers, CPAP machines)
-
Child restraint systems (car seats) for a ticketed child or when a complimentary, available space exists.
-
Diaper bags, breast pumps, and breast milk/formula.
Step 4: Special Considerations – Traveling with Specific Items
Southwest understands that not everything fits into a standard suitcase.
Sub-heading 4.1: Sports Equipment
Many types of sports equipment can be checked as part of your standard checked baggage allowance, provided they meet the size and weight limits. If they exceed these limits, special fees may apply. Always check Southwest's specific policy for your particular sport (e.g., golf clubs, skis/snowboards, surfboards, bicycles). For instance, ski equipment (skis/snowboard, poles, and boots) can be split into two bags but still count as one item as long as they meet the usual size and weight limits.
Sub-heading 4.2: Musical Instruments
Smaller musical instruments that fit within the carry-on dimensions can be brought on board as your carry-on item. Larger instruments may be allowed if space permits in the overhead bin. For very large instruments, you might need to purchase an additional seat for them, ensuring they are secured and don't block signage.
Sub-heading 4.3: Pets
Southwest allows small domesticated cats and dogs to travel in the cabin on domestic flights, provided they are in a suitable carrier. Important: The pet carrier counts as either your carry-on item or your personal item. There is also a pet fee (currently $125 one-way). Pets are not allowed in the cargo hold on Southwest flights due to temperature concerns.
Step 5: The Golden Rule – Always Verify!
While this guide provides comprehensive information, airline policies can occasionally change.
QuickTip: Focus on one line if it feels important.
-
Before your flight, especially if you have unique baggage or are close to the limits, always check the official Southwest Airlines website or contact their customer service directly. This is the most reliable way to get the most up-to-date information specific to your travel dates and itinerary.
-
Consider printing out the relevant baggage policy pages to have on hand, just in case there's any confusion at the airport.
