How often do I check Southwest fares?  If I have a flight booked, most of the time, it’s every day! 

Or, at a minimum, once a week on Tuesdays when there tend to be the lowest cheap Southwest flights.

Because I keep such a close eye on Southwest fares, I’ve really gotten to know which ones are regularly cheap, and I’m going to tell you about the ones I see ALL the time.

You can almost count on them like clockwork!

If you can score cheap flights on Southwest AND you hold the Southwest Companion Pass, which lets one person fly FREE with you for up to TWO years, you get double the value out of this rock-bottom fare.

Why You Need to Know What’s a Good Fare Price for a Destination

But first, I want to share with you the importance of knowing what a low fare price is for a destination you regularly fly to — or that is on your radar.

This is how couponers, one of which I used to be, score such good deals.

They track prices and KNOW what a good price is for a particular item. 

When that price rolls around, they make the purchase AND pair it with a coupon.

That’s how they get rock bottom prices and sometimes even free goods.

So, it’s important for you to have an idea of what a low fare looks like for you between key destination pairs.

And during this pandemic is a great time to study those fares, as they are almost at rock bottom.

That way, you’ll KNOW when there IS and ISN’T a good price available from Southwest when you’re ready to travel again.

Because Southwest often has sales that really aren’t so great (here’s how to know when a Southwest sale is a good one!), this will help you know if your destination pair is truly on sale or not.

Got it?  Good! 🙂  Now on to the cheap flights on Southwest…

 

7 Consistently Cheap Southwest Flights

While flights and fares change, there are just some city pairs that seem to ALWAYS be cheap.  Sometimes the fares are cheaper than others, but they are still always pretty low.

Here goes…

1. Cincinnati, Ohio, to Baltimore/Washington, D.C.

Southwest cheap flights

This route has gotten as low as $39, but is more typically $49-$69 during ordinary sales.

But I almost ALWAYS see it super cheap.

This is hands-down THE cheapest city from which to fly to D.C. on Southwest! 

So if you’re close to Ohio (like we are in Indianapolis) and want to visit the nation’s capital, consider making the drive to Cincinnati.

 

2. Atlanta to Nashville (and vice versa)

Prices for this route tend to hover around $49 at its lowest or more regularly between $57-$85.

Southwest added 5 non-stops daily from Nashville to Atlanta in 2018, as apparently this is a popular route!

3.  Louisville to Chicago

4.   Ft. Lauderdale to Grand Cayman

At its lowest this fare is about $59 and you’ll see it creep up to $79 at times.

We took advantage of this cheap flight over one Spring Break, taking an inexpensive flight on Allegiant to get from Indianapolis to Ft. Lauderdale and then using ~2,200 points per flight per person (with one of my four family members flying free on my Southwest Companion Pass) to fly Southwest to Grand Cayman for a total of about 13,000 points and $260 per person.

5. St. Louis to Atlanta

This is another one that is inevitably cheap.

We saw some AMAZINGLY cheap fares out of St. Louis in 2018, like 700 points per way cheap, but those have since gone away.

Atlanta hovers around $69-$89 from St. Louis.

 

6. Anywhere in California to Anywhere Else in California 🙂

Big Sur California Bridge

Southwest prices regularly go down to $39-$59 between California city pairs from nearly any one to any other one.
