Just two months after ending its long-standing “Bags Fly Free” policy, the airline has announced when it will roll out assigned seating — a significant shift from its traditional boarding process. For decades, Southwest used a first-come, first-served system, along with free checked bags, that set it apart from its competitors.

Southwest Airline's open seating policy is coming in for its final approach. The Texas-based carrier said Monday that flights with assigned seats will begin on Jan. 27, 2026, marking the end of an era in which the discount carrier for decades bucked industry norms by having passengers choose their seats during boarding.
