Yes, Southwest Airlines remains the only major U.S. carrier in 2026 to maintain its famous "Bags Fly Free" policy, allowing every ticketed passenger two checked bags for free. Each bag can weigh up to 50 pounds (22 kg) and must not exceed 62 inches in combined length, width, and height. This applies to all fare classes, from "Wanna Get Away" to "Business Select." In addition to these two checked bags, passengers are still permitted one carry-on bag and one personal item to bring into the cabin. This policy provides a significant competitive advantage for Southwest, as most other airlines now charge between $35 and $60 for a first checked bag, meaning a family of four can save upwards of $320 round-trip just on luggage fees by choosing to fly with the "LUV" airline.
