Southwest Airlines Baggage Policy Baggage Allowance, Carry-On Size & What You Need to Know

When flying with Southwest Airlines, one of the most customer-friendly aspects you'll find is their open-minded baggage policy. For being more flexible than a lot of the major U.S. carriers, Southwest streamlines packing and planning. In this guide, we're going to take you through everything you need to know about theSouthwest baggage allowance, Southwest carry-on size, and the full Southwest Airlines baggage policy, so that you don't get hit with additional fees, you can pack wisely, and you can travel hassle-free.

Southwest Baggage Policy What's Free
One of the largest benefits of flying with Southwest Airlines is their market-leading baggage policy. Passengers are permitted to check two bags free of charge, with no distinction by fare type. The policy is far more favorable than all but a few major competitors, who all charge for even the first bag checked. Whether you're traveling domestically or on an overseas flight, Southwest's baggage policy is the same, with two free checked bags, one carry-on bag, and one personal item per passengerall covered in the cost of your ticket.

Checked Baggage Dimensions and Weight Limits
Although Southwest offers two free checked bags, there are still guidelines for dimensions and weight you need to abide by. Every checked bag should not exceed 50 pounds in weight and no more than 62 linear inches when you include the length, height, and width. If your bag is over these sizes, you will have to pay extra. Bags from 51 to 100 pounds or 63 to 80 inches will cost an extra $100 per item. Any bag in excess of 100 pounds or 80 inches in size will not be accepted as checked, so it is best to have your bags weighed and measured beforehand to save any trouble at the airport.

Southwest Carry-On and Personal Item Policies
Besides your checked bag, Southwest Airlines permits each traveler to have one carry-on and one personal item in the cabin, both complimentary. The maximum carry-on size cannot be more than 24 x 16 x 10 inches, including handle and wheel. This bag should be able to accommodate the overhead bin. For your personal item, like a backpack, laptop bag, or handbag, it should fit well under the seat in front of you. Keep in mind that if your carry-on luggage is larger than permitted, you might be required to gate-check it, so checking your bag ahead of time can save you time or unnecessary handling.

Special Items and Exceptions When Traveling
If you're traveling with more than typical baggagesuch as sporting equipment, instruments, strollers, or medical suppliesSouthwest Airlines provides for those as well. A stroller and car seat can be checked for free and are not included in your two-bag limit. Skis or golf bags can be one of your two checked bags, so long as they're within the size and weight requirements of the airline. For musical instruments, if the object fits in the overhead bin or under the seat, it will be allowed onboard. If it's bigger, you might have to buy an additional seat or check it. Southwest also permits mobility aids such as wheelchairs and walkers to be checked or brought onboard free of charge.

Overweight, Oversized, and Extra Baggage Fees
Even though two bags checked are complimentary, anything over that has an associated fee. If you carry a third bag or more, each subsequent item will cost $75. For overweight bagsthose weighing 51-100 poundsyou'll pay $100 per bag. The same charges will apply for oversized bags that are 63-80 linear inches. Keep in mind that Southwest will not accept bags that weigh over 100 pounds or are more than 80 inches in size, so measure and weigh your bags before you head to the airport. These policies prevent surprise charges and simplify your check-in process.

What Parents Should Know When Traveling with Children
If you are flying with children, Southwest has a number of parent-friendly options within their policy on bags. Strollers and car seats can be checked without charge. These are not charged as one of the two free-checked bags. Additionally, diaper bags and breast pumps are permitted and are not counted as personal items, meaning parents can still carry a backpack or purse onboard. Southwest also offers family boarding between Group A and Group B, making it easier to get settled with your children and store your items in the overhead bins.

Why Southwests Baggage Policy Stands Out
The Southwest Airlines baggage policy is still one of the friendliest customer policies in the business. While other airlines charge for all but the smallest bag, Southwest has a simple and generous policy that doesn't let customers pay more without losing convenience. If you're traveling solo, with loved ones, or on business, the comfort of having two free checked bags makes dollars and centsespecially when taking longer trips where extra clothes, presents, or gear may be required. The airline's straightforward and reliable strategy for baggage makes it a top destination for cost-conscious travelers who do not wish to be nickel-and-dimed.

Final Thoughts Know the Rules and Travel Confidently
