Oh, the dreaded overweight baggage fee! We've all been there, standing at the check-in counter, nervously eyeing the scale as our meticulously packed suitcase reveals its true, hefty nature. Southwest Airlines, known for its once-generous "Bags Fly Free" policy, has undergone some significant changes as of May 28, 2025. So, if you're wondering how much does Southwest Airlines charge for overweight baggage now, you've come to the right place. Let's break it down step-by-step to ensure your next trip is as smooth (and budget-friendly) as possible!
Navigating Southwest Airlines' Overweight Baggage Fees: A Comprehensive Guide
Step 1: Let's Get Real About Your Luggage!
Before we even talk about fees, let's address the elephant (or perhaps, the overstuffed suitcase) in the room. Have you weighed your bag? Seriously, this is the most crucial first step. Don't rely on a "feels about right" estimation. Invest in a small, portable luggage scale, or at the very least, use your bathroom scale by weighing yourself, then weighing yourself holding your bag, and subtracting the difference. A few pounds can make a significant difference in your wallet!
Why is this important? Knowing your bag's weight before you get to the airport saves you from last-minute scrambling, potential repacking in the middle of the terminal, and unexpected charges that can quickly add up.
Step 2: Understanding Southwest's Standard Baggage Policy (The Baseline)
Even with the recent changes, it's essential to understand Southwest's standard checked baggage allowance, as overweight fees are applied on top of these.
Standard Weight Limit: Each checked bag must not exceed 50 pounds (23 kg).
Standard Size Limit: The total linear dimensions (length + width + height) of each checked bag must not exceed 62 inches (158 cm).
Number of Bags: As of May 28, 2025, Southwest has revised its "Bags Fly Free" policy. Most passengers will now incur fees for their checked bags:
First checked bag: $35
Second checked bag: $45
Third or more checked bags: $150 per bag
However, there are still ways to get free checked bags:
Business Select travelers and Rapid Rewards A-List Preferred members continue to receive two free checked bags.
Rapid Rewards A-List members and Southwest Rapid Rewards credit cardholders receive one free checked bag.
Step 3: Pinpointing the Overweight Baggage Fees
This is where the extra costs come into play. Once your bag surpasses the standard 50-pound limit, Southwest applies an overweight fee.
Overweight Fee for 51-70 lbs: If your checked bag weighs between 51 pounds and 70 pounds (23.1 kg - 31.8 kg), you will be charged $100 per bag, each way.
Overweight Fee for 71-100 lbs: If your checked bag weighs between 71 pounds and 100 pounds (32.2 kg - 45.4 kg), you will be charged $200 per bag, each way.
Maximum Weight Limit: Bags weighing over 100 pounds (45.4 kg) are generally not accepted as checked baggage and may need to be shipped as cargo.
Step 4: Understanding Oversized Baggage Fees (and When They Combine)
It's crucial to distinguish between overweight and oversized. An oversized bag is one that exceeds the 62-inch linear dimension limit.
Oversized Fee: If your checked bag measures over 62 inches (158 cm) up to 80 inches (203 cm) in total linear dimensions, you will be charged $200 per bag, each way.
Combined Overweight & Oversized: Southwest has a specific policy for bags that are both overweight and oversized. If your bag falls into both categories, you are typically charged only one fee – the higher of the two, or a combined fee, depending on the exact weight and size.
For example, if a bag is both 65 lbs (overweight) and 65 inches (oversized), you would pay the $200 oversized fee (since it's higher than the $100 overweight fee for 51-70 lbs). However, if your bag is 75 lbs (over 71 lbs, making it a $200 overweight fee) and 65 inches (a $200 oversized fee), you would typically pay a single $200 fee, not $400. Always confirm with Southwest's official policy or an agent at the airport for precise combined charges.
Step 5: Special Exemptions and How to Potentially Avoid Fees
While the fees can seem daunting, there are a few scenarios where you might be exempt or can mitigate the costs:
Active Duty Military Personnel: Southwest offers a generous baggage policy for active duty military personnel. They are generally exempt from checked, overweight, or oversized bag fees, provided the bags do not exceed 100 pounds and 80 inches. Always have your military ID and orders readily available.
Large Media Camera Equipment: In some cases, specific large media camera equipment may also have waived overweight or oversized fees. Check with Southwest's special baggage policies.
Sporting Equipment: Many common sporting equipment items are accepted as checked baggage, and while standard checked bag fees may apply, some oversized fees might be waived, though overweight fees generally still apply. For instance, a surfboard bag between Hawaii islands might substitute a checked bag, and excess size charges may be waived for some sports equipment, but excess weight charges can still apply. Always check the specific policy for your type of sporting equipment.
Consolidate or Ship: If you have multiple heavy bags, consider consolidating your belongings into fewer bags that meet the weight limits, or even exploring luggage shipping services for very heavy or numerous items. This can sometimes be more cost-effective than paying multiple airline fees.
Step 6: Payment and Best Practices at the Airport
Payment: Overweight baggage fees are typically paid at the airport check-in counter. Southwest does not allow prepaying for overweight baggage online.
Arrive Early: If you suspect you'll have overweight bags, arrive at the airport with plenty of time to spare. This allows you to repack, adjust, or even mail items if necessary without missing your flight.
Be Prepared: Have your payment method ready. While cash is accepted, credit or debit cards are generally preferred.
Be Polite: Airline agents are dealing with many passengers. A polite and understanding demeanor can go a long way, even if you're frustrated by the fees.
