Plus-Size Guests May Pay More for Disney Vacations, Effective January 2026

Families planning trips to Walt Disney World Resort or Disneyland Resort next year may face new travel costs, especially if they are flying with Southwest Airlines. The carrier, long known for being a budget-friendly option for Disney-bound travelers, has confirmed a major policy update that could lead some plus-size passengers to pay more for their flights, effective January 2026.

Southwest Airlines has spent the last few years reshaping several of its core policies, including ending its well-known two free checked bags rule and preparing to retire open seating in favor of assigned seats. The airline has also stated that additional legroom may soon come with an added fee. Now, another change is on the way, and it will directly affect countless passengers on flights to the Disney parks.

Beginning January 27, 2026, any Southwest Airlines passenger who cannot fit comfortably between the two armrests of a standard seat will be required to purchase an extra seat at the time of booking. Under the airline’s current system, passengers have the option to buy an additional seat in advance and request a refund later, or they can speak with airport staff on the day of travel to secure a complimentary second seat. The new rule eliminates the latter option and makes advance purchase mandatory.

Refunds will still exist, but with new restrictions. Travelers may request reimbursement within 90 days of travel, provided that the flight was not fully booked at the time of departure. If the flight sells out, no refund will be issued. Southwest Airlines also requires that both seats be purchased in the same fare class to qualify for reimbursement.

“To ensure space, we are communicating to Customers who have previously used the extra seat policy that they should purchase it at booking,” Southwest Airlines said.

Passengers who arrive at the airport without purchasing the required second seat may be asked to buy one on the spot. If the flight is at capacity, the traveler will be rebooked on a later departure.

Because Southwest is one of the most popular airlines for families traveling to Walt Disney World Resort and Disneyland Resort, this update could make Disney vacations more expensive for some plus-size guests. However, the policy applies to all Southwest passengers and is not specific to theme park travel.

The new extra-seat requirement and the airline’s upcoming transition to assigned seating both take effect in early 2026, giving Disney vacationers time to prepare as they plan next year’s trips.
