Southwest Airlines Is Launching Assigned Seating on a Flight From Puerto Rico
Southwest Airlines is set to operate its first-ever assigned-seating flight this week, and the launch will include a departure from Puerto Rico.
On Tuesday, January 27, a Southwest flight from San Juan, Puerto Rico, to Orlando, Florida will be one of the airline’s first two flights to operate with assigned seating. The flight, WN3575, will depart from Luis Muñoz Marín International Airport and marks the first time Southwest’s new seating model is used on a Caribbean route.
The San Juan departure will operate in tandem with a second assigned-seating flight leaving from another time zone, allowing the airline to test the new system across multiple operational conditions.
A Major Shift for Southwest
The flight is part of Southwest’s broader transition away from its long-standing open-seating policy. The airline has announced plans to introduce assigned seating and premium seating options in response to customer demand for more choice and flexibility.
Under the new model, Southwest will offer Extra Legroom seating, Preferred seating, and Standard seating. Passengers will receive an assigned seat prior to boarding, a significant change for an airline that has historically relied on first-come, first-served seating once onboard.
The seating changes will be paired with a new group-based boarding process, replacing Southwest’s traditional boarding-position system.
Puerto Rico is one of Southwest’s most important Caribbean markets, with extensive service to destinations across the mainland United States. Using a San Juan departure as part of the initial assigned-seating rollout signals the importance of leisure-focused routes in the airline’s evolving product strategy.
Southwest has not yet announced a timeline for a full rollout of assigned seating across its network. The January 27 flights represent an early operational step as the airline evaluates boarding flow, cabin logistics, and customer response.
More details on when assigned seating and premium options will expand to additional Caribbean routes are expected as testing continues.
