In 2026, Southwest Airlines' compensation for cancelled flights is governed by both airline policy and updated Department of Transportation (DOT) consumer protection rules. If Southwest cancels your flight or implements a "significant change" (a delay of 3+ hours domestically or 6+ hours internationally) and you choose not to travel, you are legally entitled to a full refund to your original method of payment—even for non-refundable "Wanna Get Away" fares. This refund must also include any paid bag fees or unused extras like Upgraded Boarding. If you still wish to travel, Southwest will rebook you on the next available flight at no additional cost. For cancellations within the airline's control (like mechanical issues), Southwest typically provides vouchers for meals if the delay exceeds 3 hours and may offer hotel accommodations and ground transport if you are stranded overnight away from home. While the airline often offers "Rapid Rewards" points as a gesture of goodwill, it is important to proactively request "reimbursement for reasonable expenses" through their help center if you incur out-of-pocket costs due to a significant airline-caused disruption.
