Section 1: The Core of the 2026 Southwest Airlines Fare Changes

The primary shift in the Southwest Airlines fare changes for 2026 is the transition to assigned seating. For decades, Southwest was known for its unique “first-come, first-served” boarding, but the recent Southwest Airlines fare changes have replaced this with a system that aligns more closely with global aviation standards while maintaining the carrier’s “Transfarency” philosophy.

The Four New Fare Bundles

Under the 2026 Southwest Airlines fare changes, passengers now choose from four distinct fare categories, each with its own set of rules regarding modifications:

• Basic Fare: The most restrictive tier of the Southwest Airlines fare changes. It is non-refundable and requires an upgrade to a higher tier if you wish to change your flight.
• Choice Fare: This replaces the former “Wanna Get Away Plus” and is a cornerstone of the Southwest Airlines fare changes. It allows for standard seat selection and provides transferable flight credits if you cancel.
• Choice Preferred: Offering preferred seating near the front of the cabin, this tier of the Southwest Airlines fare changes is fully refundable to the original form of payment.
• Choice Extra: The most premium option in the Southwest Airlines fare changes ecosystem, featuring extra legroom, Group 1-2 boarding, and the highest point-earning rates.

Section 2: How to Manage Voluntary Southwest Airlines Fare Changes

One of the most praised aspects of the Southwest Airlines fare changes is the continuation of the “No Change Fee” policy. Despite the shift to assigned seating, the Southwest Airlines fare changes still allow you to modify your date, time, or destination without a penalty fee, though a fare difference may apply.

Step-by-Step Flight Modification

If you need to initiate Southwest Airlines fare changes voluntarily, the process is streamlined through their official digital platforms.

1. Access Manage Reservations: Log in to the Southwest website or app to view the Southwest Airlines fare changes options for your specific confirmation number.
2. Select the Change Option: Most tickets (excluding Basic fares) allow you to view Southwest Airlines fare changes in real-time, comparing the costs of new flights.
3. Pay the Fare Difference: While the Southwest Airlines fare changes don’t involve fees, if the new flight costs more, you must pay the difference. If it costs less, you receive a credit or refund based on your fare type.

Section 3: Handling Southwest-Initiated Schedule Revisions

Occasionally, the airline itself may adjust its operations, leading to involuntary Southwest Airlines fare changes. In 2026, the protections for passengers facing these Southwest Airlines fare changes have been strengthened by federal mandates.

Refund Rights for Significant Disruptions

If Southwest Airlines fare changes your itinerary by 3+ hours domestically or 6+ hours internationally, you are eligible for a full refund to your original method of payment—even for non-refundable tickets. This rule is a vital part of the Southwest Airlines fare changes policy that ensures consumers are not financially penalized for airline-side operational shifts.

Section 4: Seat Assignments and Southwest Airlines Fare Changes

With the arrival of January 27, 2026, the Southwest Airlines fare changes regarding seating became fully active. Now, your ability to change your seat is tied directly to the fare you purchased.

• Standard vs. Preferred: If you make Southwest Airlines fare changes to your flight, your original seat selection is not guaranteed on the new aircraft. You will need to select a new seat from the available inventory for your fare class.
• Extra Legroom: For those who paid for Extra Legroom as an add-on, the Southwest Airlines fare changes state that if you voluntarily change your flight, that seat fee may be non-refundable unless you purchase a similar seat on the new flight.
