Southwest is having a 40% off sale on all their flights. Starting today (06/07) until the end of Thursday (06/09). We began our coverage last night, before the sale was officially announced. Those fares that we already mentioned are still available, but expect prices and availability to fluctuate greatly.

In this post, we’ll provide a list of every fare that we’re seeing that is priced below (or close to) its historical moving averages. This way, you can quickly cut away to the fares that are worthwhile and “really” on sale. List provided on our website in the full blog post (below, if you’re reading the full post now).

  • Key Notes: Sale covers mid-August to November. Ends Thursday. They provide a coupon-code that you don’t really need to plug in: “FALL40”.
  • Additional Savings: Sam’s Club is selling $500 Southwest gift cards for $449 [linked]. You can save an additional $50 on Southwest flights if you travel often enough or with a big enough group to burn through the gift card credit.
  • Other destinations, not on this list, are on sale, but didn’t make the cut.
  • Carry-on and checked bag are allowed for free. Southwest doesn’t charge change fees.
  • Use the fare calendar to pull up the fares [linked].
  • Sales like this on Southwest are often matched by other airlines, before committing to a purchase, do a check on BookingBuddy, Kayak, or Skyscanner to see if any other airline is offering a better deal.
  • Some fares in this list will have poor availability.

When you are ready to book your flight or hotel, please use the links on our page to begin your booking process so we receive credit for the referral.

  • Tips: Rent a car for cheaper by using Priceline’s “Express Deals”. The rental car company will be hidden until after you purchase, but this allows those companies to undercut the published rate indirectly. You can remove low quality companies from those hidden results. The trick is to use the quality filter on their website to remove any rental car company with a review rating under 7.0 and then pick the deals that survive the filter.
  • Tips: Use Tripadvisor to create a Hotel “short list”. First, plug in your dates and destination. Then select “Sort by Traveler Ranked”. Finally, select the “Traveler Ranking” filter to show “only 4* and up”. Use this resulting “short list” of hotels to find the cheapest one with a high ranking.
  • Tips: Hotel rates for Weekend dates are usually higher than the rates for Sunday through Thursday. Tripadvisor has a color-coded date calendar, red when the average hotel price for that day is more expensive, green for less expensive. You can use this to get an overview of what dates in the month are at a discount.
  • Tips: Different booking websites will often have differing routes, prices, and availability. Before you finalize your purchase, do a quick check on BookingBuddy, Skyscanner, and Kayak to see if any other site or airline is offering a better deal.


I was able to pull this up on Southwest.

Note: OTAs such as Travelocity and Priceline allow free cancellation without penalty within 24-hours after you purchase. As deals sell-out or expire quickly, this policy will allow you to “lock-in” the cheap fare while you sort out a plan. Just keep in mind that after 24-hours you will not be able to cancel without the regular penalty.
