Yes, even award fares booked using Southwest Rapid Rewards fares are discounted by 50%, no matter where you’re flying. While Southwest’s mileage program took a hit earlier this year, there is still some huge value here.

Best of all, this sale will even work if you’ve already got Southwest travel booked. Southwest never charges change nor cancellation fees, which means you could cancel an upcoming trip and rebook it at 50%. So check to see if your Southwest flight this fall is cheaper than what you previously booked.

Considering Southwest gives every traveler two checked bags for free, you could easily come out way ahead with this sale.

Want to take it to the next level? Fares booked with this 50% discount should also qualify for the Southwest companion pass – whether you book using cash or points! That means you could score a deeply discounted ticket and then bring your companion for nearly free, paying only the taxes and fees on the ticket. That’s like getting roundtrip flights for 25% of the price!


How to Take Advantage of this Southwest Sale

The world is quite literally your oyster.

So long as your trip falls between Sept. 15 and Nov. 3, you can get 50% off every single Southwest flight. Southwest flies extensively throughout the U.S., to Mexico and the Caribbean, and even out to Hawaii.

Not sure where to start? Use the Southwest Low Fare calendar. While Southwest flights won’t show up on Google Flights (or other search engines), this handy Southwest tool will help guide you to the cheapest days to travel to your destination.

Here’s a quick look at some great ways to put this sale to use:


West Coast to Hawaii from $173 RT

Southwest’s west coast hubs regularly get the best prices flying out to Hawaii, but this 50% off sale takes it to the next level.

You can fly out to the Hawaiian islands this fall from cities like San Diego (SAN), Oakland (OAK), Los Angeles (LAX), or San Jose (SJC). We’re seeing prices as low as $173 roundtrip!

Caribbean Trips for $200ish

Getting to the Caribbean can be expensive, but this sale goes a long way.

We’re seeing fares from the East Coast to San Juan, Puerto Rico (SJU) as low as roughly $200 roundtrip with this sale.

There are also substantial savings elsewhere in Mexico and the Caribbean like Cancun (CUN), Liberia in Costa Rica (LIR), Belize City (BZE), and Nassau (NAS) in the Bahamas. Just keep in mind that you’ll wind up paying more for some of these international destinations, as taxes and fees don’t get that 50% discount.


Domestic Hops Under $100 or Less

There are plenty of quick Southwest domestic routes where you can score roundtrip flights under $80 total.

That includes flights from Minneapolis-St. Paul (MSP) to Denver (DEN)…
