If you’ve flown Southwest before, you probably know they were one of the few airlines where plus-size travelers felt, well… not like an afterthought. You could book an extra seat, get a refund later, and the gate agents usually handled it with care.
Well... that’s changing.
Starting January 27, 2026, if you need more than one seat, you’ll now have to book both seats ahead of time. And the refund? It’s not guaranteed anymore.
Here’s the short version:
You now need to buy a second seat during booking if one seat doesn’t work for you with the armrests down.
You can still get your money back for the extra seat, but only if the flight isn’t full & both seats are in the same fare class
You request the refund within 90 days of your trip.
If you don’t book the extra seat ahead of time and the flight’s full, they might not let you board.
Before, you could just show up, let the agent know, and they’d usually make it work without putting you on the spot. That flexibility is gone.
This isn’t just a policy tweak. It makes flying harder and more expensive for people who already have to plan more than most travelers.
Advocates are speaking up, saying this could stop some folks from flying altogether. If you’re used to paying around $400 for a roundtrip, you might now be looking at $800. And even if you can get a refund, there’s more paperwork and rules in the way.
Southwest built its brand on being inclusive. This move feels like it’s chipping away at that.
Book both seats up front. Don’t wait.
Make sure they’re in the same fare class (this matters if you want a refund).
Set a reminder to file the refund request within 90 days.
If you’re not sure how it works, call them before booking.
It’s more work than it used to be, but it’ll save you stress at the airport.
Southwest is updating its Customer of Size policy. If you need more space, you’ll need to buy that extra seat ahead of time. Refunds are still possible, but only under certain conditions. The new rules start January 27, 2026, and yeah—this one’s hitting a nerve with users.
