Southwest Airlines Reveals Major Policy Shifts for 2026: What Travelers Must Know

The landscape of domestic air travel is shifting. Southwest Airlines is preparing for two major policy changes. These changes will take effect on January 27, 2026. The move ends two long-standing traditions for the Dallas-based carrier.

End of Open Seating

Southwest Airlines is officially ending its decades-long open-seating policy. This system allowed passengers to choose any available seat upon boarding. The Southwest assigned seating model will replace it.

The airline first announced this plan in July 2024. It is part of a broader strategy to boost revenue. The company also states that customers prefer an assigned seating model.

Customers booking flights for travel on or after the January 27, 2026, start date can now select seats. This change unlocks new options for travelers. Passengers can choose from three main seating options:

• Standard seats: Located toward the back of the cabin.
• Preferred seats: Located closer to the front of the aircraft.
• Extra Legroom seats: Located near exit rows, offering additional space.

This new system also changes the boarding process. Priority is given based on the type of seat purchased. It also affects pre-boarding for military members and families.

New Plus-Size Customer Policy

The Southwest plus-size policy is also changing on the same date. This policy, for “customers of size,” previously allowed passengers to secure an extra seat without upfront cost.

Under the previous rule, a plus-size passenger could request a free second seat at the gate. A refund was often provided after travel, even on full flights.

New Extra Seat Requirement

Beginning January 27, 2026, customers must purchase an extra seat requirement in advance. This is necessary if they cannot fit comfortably within the boundaries of one seat. The armrest is considered the definitive boundary.

This change is a significant reversal. Advocates for plus-size travelers have expressed disappointment. They noted that Southwest had been a “beacon of hope” for many.

Refunds for the second ticket are still available. However, eligibility now depends on stricter conditions. The conditions for a plus-size customer refund include:

• The flight must depart with at least one open seat.
• Both seats must be in the same fare class.
• The refund request must be made within 90 days of travel.

If a passenger does not purchase the seat in advance, they risk being rebooked. This happens if no adjacent seat is available on the flight.

Industry Context and Revenue Strategy

These Southwest policy changes 2026 are part of a major shift. The airline is moving from a simple, customer-friendly model to a more revenue-driven one. This strategy includes new fare tiers and the end of the “Bags Fly Free” policy for general passengers.

Southwest projects these changes will boost profitability. The airline forecasts a $1.5 billion increase in annual seat revenue. This contributes to a projected $4.3 billion operating profit boost by 2026. This aligns the carrier more closely with competitors. Most other major U.S. airlines, like American Airlines and Delta, have long monetized ancillary services.

Analysts have offered mixed reactions. Some see the changes as a financial positive. Others warn of the risk of eroding Southwest’s competitive strengths. The long-term success of this airline revenue strategy depends on customer reaction. It tests the balance between profit and brand loyalty.
