Southwest Airlines is extending its flight schedule into early next summer and introducing new destinations from its Nashville hub.

The airline, which usually releases its schedule eight months in advance, has just released its booking calendar through June 4, 2025, announced Wednesday. With the schedule update, the carrier has announced several key updates across its network. For starters, the carrier will expand significantly out of Nashville International Airport (BNA), which has been one of Southwest's fastest-growing hubs and newest crew bases. 

Starting April 8, 2025, the carrier will begin daily service from Nashville to Albuquerque, Jackson, and Tulsa; as well as up to 6x weekly flights to Providence and up to 5x weekly flights to Albany. In addition, the airline will offer “intra-Tennessee service for the first time” with its brand-new, once-daily service from Nashville to Memphis. 

“The new flights will boost Southwest’s scheduled presence in Nashville to an all-time high of 174 Sunday departures in April and May 2025,” the airline wrote in a statement.

The new route announcement comes as the airline is undergoing notable changes, as Southwest will introduce its first-ever overnight flights to its network next February. With today’s announcement, the airline shared a few more routes that will see redeye service — flights from Honolulu to Las Vegas and Phoenix, Kona to Las Vegas, and Maui to Las Vegas and Phoenix will be offered as red-eyes starting April 8, 2025.

However, there’s no official word just yet on when exactly the current open-seating policy will end in favor of assigned seating.  The airline’s network and booking calendar updates come as travelers have the opportunity to save up to 30 percent off Southwest’s fares using promo code “Friends” until tomorrow, Sep. 26, at 11:59 p.m. PT. Even in the carrier’s lowest “Wanna Get Away” fare class, passengers will enjoy two free checked bags and the freedom to change or cancel their flights for a future trip credit.
