Southwest Airlines has outlined plans to introduce 15 new routes linking 20 cities, with service scheduled to begin in March 2027. The expansion centers on airports where the carrier has strengthened its position in recent years, including Austin, Nashville, Orlando, San Diego and Las Vegas. Travelers planning spring getaways will gain additional nonstop options as a result.
Strongest Growth at Key Airports
Nashville International Airport and Las Vegas’ Harry Reid International Airport each receive four new routes, the largest share in the announcement. Austin Bergstrom International Airport will see expanded frequencies that support Southwest’s position as the leading carrier there, even as other airlines increase their presence. Orlando International Airport also stands to benefit from added flights that contribute to the carrier’s largest schedule on record at that facility.
These changes reflect Southwest’s strategy of reinforcing established markets while introducing service to additional destinations in Hawaii, the Caribbean and the central United States. The timing aligns with peak spring travel demand, giving passengers more direct choices for March and April journeys.
Route Additions by Airport
The new and returning flights include several daily or high-frequency options that improve connectivity from the highlighted hubs. Nashville gains daily service to Des Moines and Wichita, plus weekend flights to Aruba and St. Thomas. San Diego receives weekend flights to Kona and Lihue in Hawaii. Las Vegas adds varying-frequency service to Boston, Miami, Philadelphia and Knoxville.
Other additions feature Austin to Detroit four times weekly and Austin to San Jose, Costa Rica once weekly. Orlando gains three daily flights to New York’s LaGuardia Airport and daily service to Pensacola. Baltimore to Philadelphia operates twice daily. A small number of these routes operated previously and are returning after gaps of several years.
Distinct Service Features
One notable addition is a westbound overnight flight from Las Vegas to Honolulu, described as a reverse redeye. The flight departs Las Vegas at 2:45 a.m. local time and arrives in Hawaii at 6:10 a.m., creating an unusual domestic overnight pattern. Most redeye flights operate in the opposite direction to take advantage of time zones.
These route changes, combined with increased frequencies on existing flights, will enlarge Southwest’s overall presence at the affected airports. Passengers can expect the new schedules to support both leisure and business travel between the listed cities beginning next March.
Key timeline: All new routes start in March 2027. Some returning flights previously operated as recently as 2023.
