In addition to these exciting new routes from Nashville, Southwest announced that it will begin Saturday service between Sacramento and Puerto Vallarta, Mexico, starting on March 8, 2025.

This expansion coincides with the airline’s recent extension of its flight schedule, allowing customers to book travel through April 7, 2025.
