Via Points, Miles & Martinis, Southwest is having a flash sale.  And you can fly to many domestic and international locations starting at just $42 one-way!

For example, I found a flight from Atlanta to Chicago for $42 on September 12, 2017. 

Sale fares are valid for domestic travel between late August 2017 and mid February 2018.  Valid travel dates for international travel vary by route.

How to Book It

With Southwest’s latest sale, fares start at $42 one-way, though most fares are higher.

For example, you can fly one-way from Denver to Las Vegas for $42, San Francisco for $79, or to Cabo San Lucas, for only $170.  But you’ll need to purchase your ticket by August 24, 2017, at 11:59 pm at the origin city.

Here’s what you need to know:

  • Tickets are nonrefundable
  • Domestic travel is valid between September 5, 2017, and February 14, 2018
  • International travel is valid between September 12 and December 13, 2017, and January 9 and March 1, 2018
  • Travel to Puerto Rico is valid between September 6 and December 7, 2017, and January 16 and March 1, 2018
  • Prices do NOT include taxes & fees
  • Blackout dates apply on certain routes

While Southwest says the sale dates are no earlier than September 5, 2017, I found earlier dates on some routes.  So it’s worth taking a look, even if your travel dates fall outside Southwest’s advertised dates!

You can check Points, Miles & Martinis for how to book.  Then book directly on the Southwest website.

If you’ve already booked Southwest flights, check this sale to make sure your flights aren’t now available for less.  If they are, just cancel your Southwest flight and re-book with the lower price for free!

And don’t forget to read Million Mile Secrets contributor Lyn’s post on how to tell if a Southwest sale is worthwhile!

We love Southwest sales because when the cash price of a ticket goes down, the award ticket price goes down, too.  Because Southwest award prices are tied to the cash price.

Million Mile Secrets readers like Southwest because every passenger gets 2 free checked bags.  That can save lots of money!

Plus, if you have the Southwest Companion Pass, you can take a friend or family member with you for free for up to 2 years!  Emily and I consider the Southwest Companion Pass to be the best deal in travel.

It’s especially easy to earn the Companion Pass right now.  Because all 3 Chase Southwest credit cards are offering 60,000 points after meeting minimum spending requirements!

Bottom Line

Southwest has released a new fare sale!  Through August 24, 2017, at 11:59 pm at the origin city, you can book Southwest flights starting at $42 one-way.  For travel between September 5 and February 14, 2017.

Each route has different eligible dates, so check out the fare sale to see if it benefits your upcoming travel.

Let me know if you decide to take advantage of these cheap fares!
