The Deal at a Glance

Southwest is running one of its biggest promotions of the fall: up to 40% off base fares on select flights, booked between October 19 and 11:59 PM Pacific Time on October 22, 2026. There's no promo code — the discount appears automatically as a strikethrough on the original base fare while you shop.

The travel window is generous: November 9, 2026 through March 3, 2027, covering Thanksgiving, Christmas-season edges, and deep winter — prime time for 50+ travelers heading to warmer climates. The promotion works on cash and Rapid Rewards award bookings alike, and covers one-way or round-trip fares.

Sample fares reported by deal trackers (attributed): DansDeals found Los Angeles to San Francisco on November 11 for $49.40 (or 2,500 points + $5.60), Chicago/Midway to Fort Lauderdale on November 10 for $60.40, and LaGuardia to Dallas Love Field on November 11 for $104.39. RewardsGuru spotted Las Vegas to Los Angeles at $72 and Houston Hobby to New Orleans at $95 for November 10 — both nonstop.

50+ note: This is a "new reservations only" promotion. It applies to select flights and days — discounts vary by destination, flight, and day of week, and won't appear on some busy holiday-period flights. Always check your specific flight before assuming the discount.

Blackout Dates — the Traps to Know

For continental U.S. travel (any day of the week), these dates are blacked out:

November 28–29, 2026 (Thanksgiving return weekend)
December 26–28, 2026 (Christmas weekend)
January 2–3, 2027 (New Year return weekend)

The big surprise: Thanksgiving-eve itself (November 25) is NOT blacked out. RewardsGuru priced Orlando to Los Angeles on November 25 at $144.20 during the sale versus $223.54 normally — that's the outbound leg at a genuine discount, with the blackout only hitting the return weekend.

Hawaii, international destinations, Anchorage, St. Thomas, and Puerto Rico have additional blackouts and day-of-week restrictions (for example, continental U.S. to Hawaii/international is blacked out November 19–25 outbound, and valid only Sunday–Wednesday). Interisland Hawaii travel is not included at all. If your trip touches any of these, check the full terms on southwest.com before planning around the sale.

The 3 Senior Moves

✅ What savvy 50+ travelers are doing

Reprice flights you already booked. Southwest lets you cancel any flight for free and keep the value as flight credit. If you booked a trip inside the Nov 9–Mar 3 window at a higher fare, cancel it and make a brand-new reservation at the sale price — the promotion requires a new reservation. (Don't just change the existing itinerary: changes after purchase eliminate promotion eligibility.)
Fly out the day before Thanksgiving. November 25 is inside the sale while the return weekend is blacked out — the perfect setup for 50+ travelers with date flexibility. Fly to family on the 25th, and either return before the 28th or stay through the weekend.
Dodge the blackout traps on purpose. The Dec 26–28 and Jan 2–3 blackouts are the return legs everyone wants. Shift a Christmas trip to depart December 22 and return December 29, or push a New Year trip a few days later — the sale fares plus flexible dates beat holiday-peak pricing both ways.

Caveats — Read Before You Book

"Up to" 40% is real. Not every flight gets the full discount, and busy-period flights may show no discount at all. The 40% comes off the base fare before government taxes and fees — the advertised total still includes taxes, per DOT rules.
Bag and seat fees are back. Southwest overhauled its fare structure and now charges for checked bags and seat selection on most fares. A $72 fare with a $35 bag fee and a seat-selection charge is a different deal — price the total trip before celebrating.
Sale fares can lose to regular fares. Deal trackers found at least one case where a regular nonstop ($168.10) beat a sale two-stop itinerary — always compare the sale price against the regular fare for the exact flight you want.
Points bookings keep Southwest's best perk. As DansDeals notes, if you book with Rapid Rewards points, you can still change or cancel for free even on a basic fare — points plus this sale is the most flexible combination.

Timing tip: Book directly on southwest.com (or swabiz.com) — never through a third party for a time-limited fare sale. And with hours left before the 11:59 PM PT deadline, decide your dates first, then book calmly — a rushed wrong fare costs more than a missed sale.

Frequently Asked Questions

When does the Southwest 40%-off sale end?

Bookings must be made by 11:59 PM Pacific Time on Thursday, October 22, 2026. After that, the discounted fares are no longer available.

What travel dates does the Southwest sale cover?

Travel is valid from November 9, 2026 through March 3, 2027, on select flights. Continental U.S. blackout dates are November 28–29, 2026, December 26–28, 2026, and January 2–3, 2027. Hawaii, international, Anchorage, St. Thomas, and Puerto Rico routes have additional blackouts and day-of-week restrictions.

Is Thanksgiving included in the Southwest sale?

Thanksgiving-eve (November 25) is included — only the return weekend (November 28–29) is blacked out for continental U.S. travel. RewardsGuru priced Orlando to Los Angeles on November 25 at $144.20 during the sale versus $223.54 normally.

Can I reprice a flight I already booked?

Southwest lets you cancel flights for free and keep the value as flight credit. You can cancel an existing booking and make a brand-new reservation at the sale fare — that counts as a new reservation, which the promotion requires. Do not simply change the existing itinerary, as changes after purchase eliminate promotion eligibility.

Does the Southwest sale work with points?

Yes. The promotion applies to both cash and Rapid Rewards award bookings. DansDeals found examples like Los Angeles to San Francisco on November 11 for $49.40 or 2,500 points plus $5.60 in taxes.

Are there hidden catches in the Southwest sale?

Three to watch: the 40% is off the base fare before taxes and fees; Southwest now charges for checked bags and seat selection on most fares, so factor those in; and sale fares can lose to regular fares on some routes — one check found a regular nonstop beating a sale two-stop, so always compare before you pay.
