More flights, more cities: Southwest rolls out its biggest 2026 schedule yet

Southwest rolls out its biggest schedule yet

Southwest Airlines just made its 2026 schedule a lot bigger.

The airline announced on Feb. 12 that it will add new routes, more departures, and higher flight frequencies across five hub cities: Austin, Las Vegas, Nashville, San Diego, and Orlando. Bookings run through Oct. 31.

The headline move is Southwest’s first-ever international red-eye flight, from Las Vegas to San Jose, Costa Rica. It caps a rapid overnight expansion that didn’t exist 18 months ago.

Las Vegas leads with 282 Sunday flights

Las Vegas will hit 282 Southwest departures on Sundays, making it one of the airline’s busiest airports.

The big addition is a daily nonstop between Las Vegas and San Jose, Costa Rica, the only nonstop between those two cities on any airline. That flight also marks Southwest’s first international red-eye.

Starting Oct. 1, new red-eye flights from Las Vegas and Los Angeles to Dallas Love Field round out the overnight growth from that hub.

Red-eyes went from zero to 53 in months

For more than 50 years, Southwest never flew a single overnight route.

That changed on Feb. 13-14, 2025, when the airline launched its first five red-eyes from Las Vegas, Los Angeles, and Phoenix. By October of this year, Southwest plans to run 53 daily red-eye flights across its network.

The push into overnight flying helps the airline squeeze more use out of its planes and improve its bottom line.

Red-eyes save travelers time and money

Overnight flights give travelers a simple trade: sleep on the plane, skip an extra hotel night, and arrive early enough to catch a connecting flight.

Southwest’s morning arrival banks make those connections easier. The Las Vegas-to-Costa Rica red-eye stands out because no other airline flies that route nonstop.

All of the new red-eye flights and routes are open for booking now through Oct. 31.

Austin grows into a major base

Southwest will run 135 peak-day departures from Austin through October, and a new flight crew base opens there in spring 2026 to support that growth.

The airline also adds year-round daily service to Memphis and seasonal Saturday flights to Santa Rosa in Sonoma County and Knoxville.

Austin joins three other airports where Southwest plans its largest-ever schedule this year. The crew base signals the airline sees Austin as a long-term investment, not just a seasonal bump.

Nashville picks up nonstops to the West

Nashville is getting new nonstop flights to Reno, Nev., and Burbank, Calif. Meanwhile, Manchester-Boston Regional Airport in New Hampshire will gain Southwest service to Nashville starting Oct. 1, running five days a week on Sundays, Mondays, Thursdays, Fridays, and Saturdays.

Nashville will also hit 215 Sunday departures, a record for that airport. The new connections give travelers in both the South and New England more options without layovers.

San Diego and Orlando fill out the map

San Diego’s nonstop service to Los Cabos, Mexico, doubles from once daily to twice daily starting Oct. 1.

The airport already set records in earlier 2026 schedule announcements, with up to 139 peak-day departures planned for late summer.

Orlando, meanwhile, adds seasonal service to Albuquerque, Cleveland, El Paso, Memphis, and Louisville, timed to match demand.

Together, the two cities round out a growth push that touches every corner of Southwest’s network.

Southwest looks nothing like it did two years ago

This expansion comes just weeks after Southwest launched assigned seating on Jan. 27, ending its 53-year open-boarding tradition where passengers picked any open seat.

The airline also started charging for checked bags in May 2025, another first in its history.

Both changes came after activist investor Elliott Investment Management took a major stake in the company in 2024 and pushed for moves to boost profits.

It adds up to the most change Southwest has seen in decades.

Elliott pushed Southwest to close the gap

Elliott Investment Management pressured Southwest to catch up with competitors like Delta, United, and Alaska, which had pulled ahead financially since the pandemic.

Red-eye flights, assigned seating, bag fees, and extra-legroom seats all came out of that push. Southwest told investors in January that it expects earnings to more than quadruple this year compared to 2025.

The airline is betting that more revenue per passenger will make up for any loyalty it loses along the way.

International partnerships open new doors

Southwest has signed partnerships with six international carriers, including Icelandair, Turkish Airlines, and EVA Air.

These deals let travelers book connecting flights to Europe, Asia, and the Middle East on a single ticket. The Icelandair partnership launched in February 2025 with connections through Baltimore.

The Turkish Airlines partnership started in early 2026, connecting through 10 shared U.S. airports. For an airline that built its name on domestic routes, the international reach is a big shift.

Some things at Southwest stay the same

Not everything has changed. Southwest still skips change and cancellation fees on most fares.

Rapid Rewards points still have no blackout dates and don’t expire. The airline flies an all-Boeing 737 fleet, which keeps operations simple.

And free Wi-Fi is now available for Rapid Rewards members on every flight through a T-Mobile partnership. For loyal customers worried about losing what they love, those basics remain in place.

All new routes are open for booking now

Every new route and added departure is available for booking through Oct. 31, 2026. Southwest’s no-change-fee policy means travelers can lock in a fare now and adjust later if the price drops.

Rapid Rewards points work on any available seat on any flight.

The schedule covers all five hub cities and dozens of new connections, so now is the time to start planning summer and fall trips.
