## Summary

Southwest is automatically taking up to 40% off select base fares, with no promo code, on bookings made October 19 through 22, 2026 for travel November 9, 2026 through March 3, 2027. The discount applies at booking.

The reduction is up to 40%, not a flat cut on every itinerary, and it covers base fares on select flights only. Interisland Hawaii travel is excluded. Continental U.S. trips are blacked out November 28 and 29, 2026. Further domestic blackouts run December 26 through 28, 2026 and January 2 and 3, 2027. Travel from the continental U.S. to international destinations, Hawaii, St. Thomas and San Juan is blacked out November 19 through 25, 2026 and December 17, 2026 through January 5, 2027. The reverse direction is blacked out November 27 through December 1, 2026 and again December 17, 2026 through January 5, 2027.

Existing reservations can be canceled and rebooked to take the sale fare.

Search Southwest October 19 through 22, 2026 and rebook held tickets when the new base fare is lower.
