Navigating Southwest Airlines Baggage Policy: A Step-by-Step Guide

| How Many Pounds Does Southwest Airlines Allow |
Step 1: Understand the "Bags Fly Free" Evolution (and What It Means for YOU!)
Alright, let's start with the big one. For years, Southwest was famous for its "Bags Fly Free" policy, a true differentiator in the airline industry. However, as of May 28, 2025, this policy has undergone a significant change for most travelers. It's crucial to note that this date refers to when the flight was booked or voluntarily changed, not the travel date itself.
So, what's the deal now?
For most travelers booking on or after May 28, 2025: You will now pay for your first and second checked bags. This brings Southwest's policy more in line with other major US airlines.
But don't despair! There are exceptions: Southwest still offers free checked bags for certain categories of passengers. We'll get into those details in Step 3.
Your Action: Before you even think about packing, check the date you booked your flight. If it was before May 28, 2025, and you haven't voluntarily changed it, you might still be eligible for the old "Bags Fly Free" policy. If it was on or after, then the new fee structure likely applies to you.
Step 2: Grasping the Core Weight and Size Limits for Checked Bags
Regardless of whether your bags are free or not, there are strict weight and size limits you must adhere to for checked baggage. These limits are universal across Southwest's network, including international flights.
Sub-heading: The Golden Rules for Checked Luggage
Maximum Weight: Each checked bag must not exceed 50 pounds (approximately 22.7 kg). This is a non-negotiable limit for standard baggage.
Maximum Size: The total linear dimensions (length + width + height) of each checked bag must not exceed 62 inches (approximately 158 cm). Remember to include handles and wheels in your measurements!
Your Action: Measure and weigh your luggage before you leave home. Invest in a luggage scale – they are inexpensive and can save you a significant amount of money in overweight baggage fees. Use a measuring tape to calculate the total linear dimensions. Don't eyeball it; be precise!
QuickTip: A slow read reveals hidden insights.
Step 3: Discovering Who Still Gets Free Checked Bags
While the "Bags Fly Free" policy has shifted for the general public, Southwest still offers complimentary checked bags to several traveler categories. If you fall into one of these, you're in luck!
Sub-heading: Eligibility for Complimentary Checked Bags
Business Select® Customers: If you've booked a Business Select fare, you are entitled to two free checked bags.
Rapid Rewards A-List Preferred Members: These elite loyalty members also receive two free checked bags.
Rapid Rewards A-List Members: As an A-List member, you get one free checked bag.
Southwest Rapid Rewards Credit Cardholders: Many co-branded Southwest credit cards offer the benefit of one free checked bag. Be sure to check the specific terms of your card.
Active-Duty Military Personnel: With a current, valid military ID, active-duty military passengers are exempt from the two-piece baggage limit and will not be subject to excess, oversize, or overweight baggage charges, provided each piece does not exceed 100 pounds in weight and 80 inches in size. This is a significant exception!
Your Action: Check your fare type, Rapid Rewards status, and credit card benefits. If you're eligible for free bags, make a note of it and ensure you understand how many you can check without incurring fees.
Step 4: Understanding the Costs of Additional, Overweight, and Oversized Bags
If your bags don't meet the standard free allowance or exceed the weight/size limits, you'll face fees. These can add up quickly, so it's essential to be aware of them.
Sub-heading: Decoding Baggage Fees
First Checked Bag (for those not eligible for free bags): Approximately $35
Second Checked Bag (for those not eligible for free bags): Approximately $45
Third or More Checked Bags: Each additional bag beyond the first two will cost approximately $150.
Overweight Baggage Fees:
For bags weighing 51 to 70 pounds: Approximately $100 per bag.
For bags weighing 71 to 100 pounds: Approximately $200 per bag.
Note: Bags weighing over 100 pounds are generally not accepted as checked baggage and may need to be shipped as air cargo.
Oversized Baggage Fees:
For bags exceeding 62 inches but not more than 80 inches (length + width + height): Approximately $200 per item.
Note: If a bag is both overweight and oversized, generally only one fee (the higher one) will apply, as long as it doesn't exceed 100 pounds or 80 inches.
Your Action: If you anticipate needing to check more bags or have bags that might be overweight/oversized, factor these potential costs into your travel budget. It's often cheaper to ship items separately via a courier service than to pay airline excess baggage fees, especially for very heavy or large items.
Step 5: Master the Carry-On and Personal Item Rules
Beyond checked baggage, Southwest also has specific rules for what you can bring with you into the cabin. This is your chance to strategically pack essentials and avoid checking a bag if possible!
Tip: Reading on mobile? Zoom in for better comfort.
Sub-heading: Your Cabin Baggage Breakdown
Carry-On Bag: You are allowed one carry-on bag.
Maximum Dimensions: 24" (L) + 16" (W) + 10" (H), including wheels and handles.
Weight Limit: There is no stated weight limit for carry-on bags, but you must be able to lift it into the overhead bin unassisted.
Placement: Must fit in the overhead bin.
Personal Item: In addition to your carry-on, you can bring one personal item.
Maximum Dimensions: Approximately 16.25" x 13.5" x 8".
Weight Limit: No stated weight limit.
Placement: Must fit under the seat in front of you. Examples include a purse, briefcase, laptop bag, or small backpack.
Your Action: Be mindful of these dimensions. If your carry-on is too large, it may be gate-checked (possibly for a fee if it also exceeds checked bag limits). Ensure your personal item truly fits under the seat to avoid any last-minute shuffling.
Step 6: Special Items – From Sports Gear to Musical Instruments
Traveling with something unusual? Southwest has policies for a variety of special items.
Sub-heading: A Glimpse at Special Baggage
Sports Equipment: Many common sports equipment items (like golf clubs, skis, snowboards, fishing rods) can be checked as part of your standard baggage allowance if they meet the 50 lbs and 62 inches linear dimensions. If they are oversized or overweight, specific fees apply. Some items, like surfboards, have their own dedicated fees. Always check Southwest's official website for the most up-to-date information on your specific item.
Musical Instruments: Small instruments that fit in the overhead bin or under the seat can be carried on. Larger instruments may need to be checked or require the purchase of an additional seat.
Assistive Devices and Child Items: Wheelchairs, strollers, car seats, and other assistive devices or child-related items are typically not counted towards your baggage allowance and can be checked free of charge.
Your Action: If you're traveling with any special items, always consult the Southwest Airlines website for their specific policies and any associated fees. Don't assume – confirm!
Step 7: Checking Your Bags at the Airport: Timing is Key!
Once you've packed and know your baggage allowances, the final step is actually checking your bags at the airport.
Sub-heading: Airport Check-in Tips
Domestic Flights: Southwest recommends checking baggage at least 45 minutes prior to your scheduled departure.
International Flights: For international flights, the recommended check-in time for both passengers and baggage is at least 60 minutes prior to scheduled departure. For flights departing Aruba, this is extended to 75 minutes. Bags presented less than these times may not make your flight.
Self-Tagging: At some airports, Southwest offers self-tagging kiosks, which can help speed up the process.
Curbside Check-in: Curbside check-in is generally available for domestic flights but not for international itineraries.
Your Action: Arrive at the airport with plenty of time, especially if you're checking bags. Rushing can lead to mistakes, missed flights, or last-minute fees.
QuickTip: Every section builds on the last.
