Southwest Airlines Checked Baggage Policy provides an industry-leading checked baggage policy with two free checked bags allowed per passenger. This benefit is consistent across all fare classes, helping families and business travelers avoid surprise fees. Each bag must not exceed 50 pounds or 62 inches. If your luggage is too heavy or large, you’ll face additional fees. The generous allowance sets Southwest apart from other U.S. airlines and adds incredible value to your fare. Before traveling, confirm the latest rules on the airline’s official site. Luggage tags and early airport arrival are also recommended for a smooth check-in experience.
