Southwest Airlines Baggage Policies

Understanding Southwest Airlines baggage policies is key to avoiding surprises at the airport. Knowing the size and weight limits for your luggage can save you time and extra fees. Let’s break down what you need to know about carry-on allowances, checked bag limits, and weight restrictions.

Carry-on Allowances

Southwest allows one carry-on bag and one personal item per passenger free of charge. The carry-on bag must fit in the overhead bin and measure no more than 10 x 16 x 24 inches. Your personal item, like a purse or laptop bag, should fit under the seat in front of you.

Have you ever tried to squeeze an oversized bag into the overhead bin only to be asked to check it? Measuring your carry-on before you travel can prevent this hassle. Remember, even if your bag looks small, Southwest’s specific dimensions matter.

Checked Bag Limits

Southwest Airlines lets you check up to two bags for free on most fares. Each checked bag can measure up to 62 linear inches(length + width + height). If your bag exceeds this, you’ll face oversize baggage fees, which can add up quickly.

Think about your last trip: did your checked bag fit those limits? If not, consider a smaller suitcase or repacking to avoid fees. Also, certain fare types and credit card holders may get additional benefits, so check your ticket details.

Weight Restrictions

Each checked bag on Southwest should weigh no more than 50 pounds. Bags over this weight will incur overweight fees, which are quite steep. Southwest does not have weight limits for carry-ons, but you should be able to lift your carry-on into the overhead bin without help.

Weigh your luggage at home to avoid surprises. If your bag tips the scale, redistribute items or remove non-essentials. This step can save you money and reduce stress at the airport.

Measuring Your Luggage

Measuring your luggage correctly is important before flying with Southwest Airlines. It helps avoid extra fees and travel delays. Knowing the exact size ensures your bag meets the airline’s rules.

Southwest Airlines has specific size limits for both checked and carry-on bags. Measuring your luggage carefully can save money and stress at the airport.

Tools Needed For Measurement

Gather a tape measure or a ruler. A soft measuring tape works best for curved surfaces. Use a flat surface to place your luggage while measuring. A notebook or phone can help record measurements.

Measuring Length, Width, And Height

Measure the longest side first. This is usually the length. Then measure the width, the shorter side on the bottom. Finally, measure the height from the base to the top. Write down each number.

Use inches for all measurements. Southwest Airlines size limits are usually in inches. Keep your measurements exact to avoid confusion later.

Including Wheels And Handles

Include wheels and handles in your measurements. They add extra length and height. Measure from the ground to the top of the handle fully extended. Add the wheels’ depth to the width measurement.

Ignoring wheels and handles may cause your bag to be too large. Always count every part of your luggage.

Size Limits For Carry-on Bags

Knowing the size limits for carry-on bags on Southwest Airlines helps avoid extra fees. It also makes travel smoother and less stressful. Southwest has clear rules about how big your carry-on can be.

These rules apply to all passengers. Measuring your bag before the trip saves time at the airport. Here’s what you need to know about the size limits for carry-on bags.

Maximum Dimensions

Southwest Airlines allows carry-on bags up to 10 x 16 x 24 inches. This size includes handles and wheels. Bags larger than this may not fit in the overhead bin.

Measuring your bag carefully is important. Use a tape measure to check height, width, and depth. Keep your bag within these limits to avoid problems at the gate.

Common Carry-on Bag Sizes

  • Small backpacks usually measure around 9 x 14 x 20 inches.
  • Standard rolling carry-ons often measure 9 x 14 x 22 inches.
  • Compact duffel bags vary but often fit under the size limits.

Many travelers choose bags that fit these common sizes. This choice helps ensure the bag is accepted without extra charges. It also makes packing easier and more efficient.

Size Limits For Checked Bags

Understanding the size limits for checked bags on Southwest Airlines can save you from unexpected fees and hassles at the airport. Knowing exactly how big your luggage can be ensures a smooth check-in experience and lets you pack smartly. Let’s break down the key details you need to measure your bag correctly.

Maximum Dimensions

Southwest Airlines allows checked bags with a total dimension (length + width + height) of up to 62 inches. This means you need to add the height, width, and depth of your suitcase to see if it fits within the limit.

For example, if your bag measures 30 inches tall, 20 inches wide, and 10 inches deep, the total is exactly 60 inches, which is acceptable. Always measure your bag with wheels and handles included, as they count toward the total size.

Have you ever been surprised by a bag that looked small but exceeded the limit because of its shape? Using a tape measure and writing down dimensions before your trip can prevent last-minute stress.

Oversized Bag Fees

If your checked bag exceeds 62 inches in total dimension, Southwest charges an oversized bag fee. This fee can add a significant amount to your travel expenses, so it’s best to avoid it.

The fee for oversized bags is typically around $75, but it’s good to check Southwest’s latest policy before you fly. This charge is per bag, so multiple oversized bags mean multiple fees.

Imagine saving that $75 by simply repacking or choosing a slightly smaller suitcase. Could adjusting your packing strategy help you avoid this extra cost? Keeping your luggage within the size limits lets you focus on your trip, not extra fees.

Tips To Avoid Extra Fees

Avoiding extra fees on Southwest Airlines starts with careful luggage planning. Measuring your bags correctly helps prevent surprises at the airport. Paying attention to size and weight limits saves money and stress. Follow these practical tips to keep your luggage within Southwest’s guidelines.

Packing Light And Smart

Choose only essentials for your trip. Smaller bags are easier to handle and less likely to exceed size limits. Use a checklist to avoid overpacking. Distribute weight evenly to meet Southwest’s weight restrictions. Keep heavy items in your carry-on to avoid checked bag fees.

Choosing The Right Luggage

Select luggage that fits Southwest’s size rules. Soft-sided bags can compress better than hard shells. Look for lightweight suitcases to maximize your weight allowance. Measure your bag before travel to confirm it meets the 62-inch size limit (length + width + height). Avoid bags with bulky handles or wheels that add extra inches.

Using Compression Bags

Compression bags reduce bulk and create more space. They help fit more items without increasing size. Use vacuum-sealed bags for clothes and soft items. These bags protect belongings and keep your suitcase organized. Compression bags make packing efficient and cost-effective.
