Southwest Airlines is considering changes to its quirky boarding and seating practices

DALLAS (AP) — Southwest Airlines is studying changes to its quirky boarding and seating policies as it searches for ways to raise more revenue.

Airline officials say they are studying possible changes but won’t have anything to announce until September. That tease is leading to speculation about whether Southwest might ditch some longstanding traditions, including the practice of passengers picking their own seats only after they board a plane.

CEO Robert Jordan says he is proud of Southwest’s “product,” but it was developed when flights weren’t as full as they are today, and customers’ preferences change over time, prompting the “deep dive” into “transformational options” in boarding and seating.

“Early indications, both for our customers and for Southwest, look pretty darn interesting,” he told analysts and reporters Thursday.

Every other major U.S. airline sells first- or business-class seats with more room and amenities. They assign seats long before passengers arrive at the airport. And increasingly, they charge extra if economy-class passengers want to pick a particular seat, such as one in an exit row or near the front of the cabin.
