Frequently Asked Questions
Does Southwest still offer free checked bags in 2026?
Yes. Southwest allows every passenger to check two bags free of charge on all fare types, as long as each bag stays within the 50 lb weight and 62 linear inch size limits.
What happens if my bag is over 50 pounds?
Southwest charges approximately $75 for bags weighing between 51 and 100 pounds. Bags over 100 pounds are not accepted as passenger luggage. Always weigh your bag at home before heading to the airport.
How is the 62-inch size limit calculated?
You add the bag’s length + width + height together, including wheels, handles, and external pockets. Most standard 28-inch suitcases measure around 58–62 linear inches total.
Can I bring a carry-on in addition to two checked bags?
Yes. Southwest allows one carry-on bag (up to 24 × 16 × 10 inches) and one personal item in the cabin at no charge, in addition to your two free checked bags.
Is Southwest cheaper than Frontier or Spirit for bags?
Yes. Frontier and Spirit charge for carry-ons and checked bags, with gate prices reaching $99 per bag. Southwest’s free two-bag policy can save a family of four $200–$400 compared to ultra-low-cost carriers.
