Southwest Airlines Reverses Plus-Size Passenger Policy: New Extra-Seat Rules

Southwest Airlines has restored greater flexibility for plus-size passengers after criticism of rules that required travelers needing additional space to buy a second seat before flying.

Airport agents can now provide an adjoining seat free of charge when one is available. The change removes the strict advance-purchase requirement, but passengers could still be moved to a later flight if their scheduled departure has no suitable space.

The change at a glance

• An extra seat can be requested at the airport without advance payment.
• The complimentary seat depends on availability.
• Travelers can still purchase a second seat to guarantee the space.
• A passenger may be rebooked if the original flight is full.
• Refunds for purchased seats remain subject to applicable conditions.

Southwest continues to recommend reserving an additional seat during booking when a traveler knows the space will be required.

How the airport option works

A qualifying customer can speak with an agent at the airport and request another seat. If an adjoining seat remains open, the agent is authorized to provide it without an additional charge.

If no suitable seat is available, Southwest says it will help accommodate the passenger on a later departure. The airline has not promised that the replacement flight will leave immediately.

Passengers relying on this option should arrive early. Speaking with an agent before boarding begins provides more time to review seat availability or arrange another flight.

How Southwest determines whether another seat is needed

The policy does not use a published weight limit or clothing size. Southwest considers the armrest the boundary between seats. A traveler may require additional space if they cannot sit within both armrests without extending into the adjoining seat.

Seat dimensions can vary by aircraft and location inside the cabin. Customers who are uncertain can contact the airline before traveling and review Southwest’s current extra-seat guidance.

A policy that changed twice in 2026

Southwest previously allowed eligible passengers to request a complimentary seat at the airport or purchase one in advance and seek reimbursement later.

That approach became more restrictive on January 27, 2026. Travelers requiring additional space were expected to purchase a second seat before departure and pay any associated fare or seat charge.

Reimbursement was not guaranteed. It could depend on whether the flight departed with an open seat, whether both reservations were made in the same fare class and whether the refund request was filed within the required period.

Following customer criticism and an internal review, Southwest softened the advance-purchase rule in late May. Reports published on August 3 brought renewed attention to the decision, but the reversal itself was not introduced in August.

Why the January rules caused concern

Some plus-size passengers said the policy created unexpected expenses and left sensitive decisions to airport employees. Without a single weight or measurement standard, travelers worried that enforcement could vary between agents or airports.

Travel adviser Jason Vaughn of Fat Tested Travel also raised a practical concern: passengers who believed the second seat would not be refunded might reserve only one seat and hope for enough room.

That could leave gate agents or flight attendants resolving the issue shortly before departure, while also affecting the traveler and anyone seated nearby.

Free airport seat or paid reservation?

The airport option avoids paying for a second ticket, but it carries the risk of rebooking. The advance-purchase option guarantees the space but requires the traveler to pay first and verify whether reimbursement is available.

Passengers buying two seats should keep both reservation confirmations, receipts and boarding records. Those traveling on connecting itineraries should ask how refund and availability rules apply to each flight segment.

Advance booking may be the safer choice for travelers with cruises, international connections, business appointments, prepaid hotels or events that cannot be rescheduled.

What the reversal does not change

The Customer of Size policy is separate from Southwest’s baggage charges. The airline has not restored its former free checked-bag benefit through this decision.

The revision comes during a much wider business overhaul. Southwest has made organizational changes that included layoffs affecting approximately 75 roles.

It is also adjusting where it operates flights, including plans to cut seven seasonal nonstop routes from St. Louis.

The revised policy gives passengers a choice, but not a guaranteed free seat on every departure. Travelers must weigh the certainty of purchasing the space against the possibility of receiving it free at the airport—or being moved to a later flight.
