Southwest Airlines is changing another longstanding seating policy. Beginning Jan. 27, 2026, the airline will require passengers who “encroach upon the neighboring seat” to proactively purchase an additional ticket, which might not be refunded. Previously, passengers could either pay the cost of an extra seat ahead of time — and later receive a refund — or show up at the airport and request an extra seat at no charge, which made Southwest a carrier of choice for many plus-size passengers. Southwest’s sweeping changes in recent months have flustered and even angered previously loyal customers, including ending open seating and charging checked baggage fees. The carrier also announced changes to its domestic routes and is considering expanding its international service. The airline’s recent moves have left many passengers with the impression that the carrier is becoming like most other major airlines. One travel agent pointed out that the airline’s new plus-size passengers rule could be cost prohibitive for many passengers. “If you’re already budgeting and now you’ve got to add $300 to $400 to your budget, that may mean less travel.”
