There have been so many changes to Southwest Airlines recently, and if you haven’t flown with them in a while, you’ll want to make note of these new rules.

Southwest has been shaking things up in the airline industry. Recently, Southwest became the first airline to fly with a secondary cockpit barrier in place. This is a safety feature that adds extra protection on the flight decks and has been supported by pilot unions. But that’s not all, there are 3 new rules for flying with Southwest.
1. Checked Bags Are No Longer Always Free
Southwest has changed its bag policy. As of May 28, 2025, for many fare types, free checked bags are no longer included by default. Previously, free checked bags were a big perk that differentiated Southwest. Now, unless you’re flying under a fare class or status that includes bag benefits, you’ll likely need to pay. The airline will continue to offer two free checked bags to its Rapid Rewards A-List Members and others who book seats with Business Select. Regular A-List Members, Rapid Reward credit card members, and other select passengers will be able to check one bag for free.

2. Assigned Seating Replaces Open Seating
One of the major shifts: the elimination of open seating. Southwest is moving to a system with assigned seats for flights departing January 27, 2026, and later. You’ll be able to select your seat at booking (depending on fare and status), rather than grabbing whatever’s left when you board.

There are also new seating choices:
- Extra Legroom Seats, which provide a “roomier experience with more legroom to stretch out, at the front of the cabin and near the exit rows, with up to five additional inches* of extra legroom compared to Standard and Preferred seats. Plus, earlier access to bin space, enhanced snacks, and complimentary premium beverages.”
- Preferred Seats, which offer “standard legroom seats near the front of the cabin.”
- Standard Seats, which offer “standard legroom seats located in the back of the cabin.”

3. “Customer of Size” / Buying a Second Seat Changed
Starting on January 27th, 2026, Southwest will require passengers who take up more space than one seat allotment to purchase an additional ticket before the flight. In the past, passengers could pay the cost of an extra ticket ahead of time and receive a refund after, or request an extra seat at the airport for no extra charge. This is another major change for the airline, which has left many long-time customers frustrated with the company.
