Southwest on Tuesday announced a series of route additions and frequency increases as it published its schedule through Sept. 30, 2026. The carrier said the latest update includes growth in Southern California and new links to Hawaii.
Beginning Aug. 4, Southwest will launch daily service between San Diego and Santa Barbara. The airline will also double the number of daily flights linking San Diego with Portland, Salt Lake City, and Seattle on the same date.
According to the carrier, the changes will bring San Diego to a record 139 peak-day departures in late summer 2026.
New Hawaii Service
The airline will further expand from Long Beach, where service to Portland and Seattle will resume on Aug. 4, 2026. Both routes will operate six days per week.
Southwest is also adding new Hawaii service from the Los Angeles Basin. The carrier plans to begin peak-day service between Burbank and Honolulu on Aug. 4, going head-to-head with Alaska. A new daily Ontario–Honolulu flight will launch earlier in the season on June 4.
