Southwest Reverses Its Customer of Size Policy: What It Means
Aloha friends. Southwest just walked back one of its most talked about changes of the year. As of late May 2026, plus size passengers no longer have to buy a second seat in advance, and gate agents can once again hand you a free extra seat when there is room beside you on the flight. If you fly Southwest from Hawaii, interisland or to the mainland, here is the quick version of what changed and what it means for you.
What Southwest just changed
Back in January, when Southwest switched from open seating to assigned seats, it also tightened its long running Customer of Size policy. Passengers who needed more than one seat were told to pre purchase that second seat, and refunds came with strings attached. That sparked a wave of complaints, viral videos, and pushback from advocacy groups who felt the rule was confusing and unfair.
Southwest listened. The update, which took effect immediately, restores the part people loved most: you can get that extra seat at no cost from a gate agent when adjacent space is open. You are no longer required to pay for it up front and chase a refund later.
What the policy says now
Per Southwest's own statement, agents at the airport are now empowered to provide an additional seat at no extra cost to Customers who require one. If a free seat is not available, the airline says it will work to rebook you on a later flight. Southwest still recommends booking the extra seat in advance so you are not caught out on a packed flight.
The free extra seat is only guaranteed when adjacent space is actually open. On a full flight you may be asked to take a later departure. If your trip is on a peak travel day or a sold out interisland hop, booking that second seat in advance is still the safe play.
Wait, didn't they just tighten this rule?
They did, which is why this is confusing. Here is the short timeline so you can keep it straight:
- May 2025: Bags Fly Free ended after 54 years. Southwest now charges 35 dollars for the first checked bag and 45 dollars for the second.
- January 27, 2026: Assigned seating launched, and customers of size had to pre purchase a second seat, with refunds tied to three conditions.
- Late May 2026: After sustained backlash, Southwest reversed course and brought back the free extra seat at the gate when space allows.
So the policy was not deleted. It swung back toward the more accommodating version that plus size travelers had long called one of the friendliest in the industry. The big practical win is that no one is forced to lay out cash up front anymore.
What it means for Hawaii travelers
Southwest is a real player for kamaʻāina. It flies the interisland routes between HNL, OGG, KOA, LIH, and ITO, and it connects us to the West Coast and beyond. So this change touches a lot of local itineraries.
- Interisland flyers: short hops sell out fast, especially around holidays and big events. If you need the extra space, the gate option is back, but a full ʻohana weekend flight may not have an open seat to give.
- Mainland and connection travelers: longer flights mean more time in the seat, so the free second seat matters more, and so does planning ahead on busy days.
- Everyone in the cabin: when a passenger who needs more room actually gets it, the person in the next seat keeps their full seat too. More space for one usually means more comfort for both.
If you are weighing Southwest against flying Hawaiian for your interisland travel, the seating experience is now one more thing in the mix alongside earning and redemption. I break that head to head down in more detail over here: [LINK: Huakaʻi by Hawaiian vs Southwest ʻOhana Rewards for kamaʻāina].
Here's the move
If you or someone in your party may need an extra seat, here is how I would play it on Southwest right now:
- On a flexible or off peak day, you can request the free extra seat from a gate agent at the airport.
- On a peak day, a sold out interisland flight, or a tight connection, book the second seat in advance so you are not left waiting for the next departure.
- Watch the bag fees too. A Southwest co branded card or A List Preferred status still waives checked bag charges, which adds up fast for a Hawaii family hauling gear to the mainland.

I will be honest with you on this one, because I lived a small version of it last month. I booked a last minute flight for a work conference and ended up next to a fellow passenger who needed more room than a single seat gave them. And you know what? Praise God for Starlink, because the wifi kept me happily occupied the whole flight and the time flew by. No complaints from me.
Here is what I keep coming back to. The answer to a tight cabin is not asking anyone to apologize for the body they travel in. The answer is more room for everyone. When the person beside you gets the seat they actually need, you get your full seat back too. That is a win for both of you, and it is a kinder way to fly.
That is why I think bringing back the free extra seat is the right call. Charging people up front for the space they need never sat well with me, and Southwest reading the room and reversing it is a good look. My only caution is the fine print: the free seat depends on space, so plan ahead on busy days.
