Southwest Airlines has installed extra legroom on 47% of its planes

Southwest Airlines technically doesn’t launch assigned seating for another four months. And if you’re flying with the airline to Hawaii, you’ll be on a plane that already has its new extra-legroom seats.

But since the airline hasn’t ended its open seating policy just yet, that means a prime boarding position could land you one of those spacious seats at no added cost.

As of this week, the Dallas-based carrier has finished installing extra-space rows on all of its Boeing 737 MAX 8 jets — the same aircraft it uses on flights to and from the Aloha State. It’s a milestone in Southwest’s push to get all of its planes reconfigured with extra-legroom accommodations before late January 2026, when it officially launches open seating and starts charging extra for those roomier rows.

So, think of this as the “soft launch,” of sorts, during the final few months of first-come, first-served seating.

Nearly half of Southwest planes now have extra legroom

It’s not just Southwest’s Hawaii flights that have its new extra-legroom seats, either. As of Sept. 8, the carrier had retrofitted 380 of its planes with the new seating setup — about 47% of its fleet.

As part of the cabin revamp, crews also installed in-seat power outlets and larger overhead bins on all of Southwest’s MAX 8 planes that fly its longer routes.

Southwest’s MAX 8 (and Boeing 737-800) planes that have been retrofitted now feature five extra-legroom rows at the front of the aircraft and three additional rows of elevated seating near the mid-cabin emergency exit.

We should note that these are just regular coach seats with more legroom. So for now, as you board a plane that has these spacious rows, you may have to look closely to see what type of seat you’re choosing.

Southwest recently began installing specially-colored headrests to make its extra-legroom seats stand out. But you’ll only notice the colors on about a quarter of the planes that have the new seating setup.

Here’s what the MAX 8 and 737-800 seat map will look like once the aircraft is outfitted with the new configuration.

Southwest began refitting its planes this spring after announcing its shift to assigned and extra-legroom seating in 2024.

The carrier has already started selling flights with assigned seating, which officially begins Jan. 27, 2026. At that point, customers who purchase the airline’s newly named Choice Extra fare will have access to extra legroom.

Top-tier Rapid Rewards A-List Preferred members will be able to select one of those seats for free within 48 hours of a flight’s departure. Travelers who carry the Southwest Rapid Rewards® Priority Credit Card (see rates and fees) the Southwest® Rapid Rewards® Performance Business Credit Card (see rates and fees) will be able to do the same.

Best ways to get a Southwest extra-legroom seat in 2025

Between now and January — while Southwest still has open seating in place — your best bet for scoring one of the extra-legroom seats is to secure an early boarding position.

The airline sells Upgraded Boarding as an optional add-on within 24 hours of departure. This guarantees an A1-15 boarding position — and, in essence, ensures an extra-legroom seat will be available when you get on the plane.
