Scoring a bargain deal on airfare this fall and winter just got easier with a limited-time sale from Southwest Airlines, featuring major discounts on most of its routes. 

The limited-time sale, which ends tomorrow, Sep. 19, at 11:59 p.m. PT, can be booked for upcoming travel dates depending on the destination. However, this latest Southwest promotion excludes all flights to (or from) Orange County, Calif., and there are several other blackout dates to note: 

  • Continental U.S. flights are valid between Oct. 1 and Dec. 18 but excluded from Nov. 26 to 27
  • Flights to Hawaii, Puerto Rico, and international destinations are valid between Oct. 1 and Feb. 10, but excluded from Nov. 21 to 25 and Dec. 18 to Jan. 7
  • Flights from Hawaii, Puerto Rico, and international destinations are valid between Oct. 1 and Feb. 10, but excluded from Nov. 29 to Dec. 3 and Dec. 18 to Jan. 7
  • Interisland Hawaii flights are valid between Oct. 1 and Feb. 10, but excluded from Dec. 18 to Jan. 7

To find the best deals, travelers can head over to Southwest’s Low Fare Calendar tool to see prices by day in a calendar view. No promo code is required to activate the savings, and Travel + Leisure found several great deals at the lowest $49 price point: 

  • Atlanta (ATL) to/from Orlando (MCO)
  • Honolulu (HNL) to/from Kona (KOA)
  • Phoenix (PHX) to/from Los Angeles (LAX)
  • San Antonio (SAT) to/from Dallas (DAL)
  • Denver (DEN) to/from Montrose/Telluride (MTJ)
  • Charlotte (CLT) to/from Baltimore (BWI) 

All of these fares can be booked in Southwest’s “Wanna Get Away” fare class, which offers free flight changes and cancellations for a future trip credit. The airline has the most generous bag policy, allowing passengers to bring a personal item and a carry-on bag, as well as check two free bags.
