Before you buy Rapid Rewards points, know these five things: your discount is personal, a point is worth about 1.3 cents, bought points don't count toward the Companion Pass, the purchase isn't airfare to your card, and point bookings are unusually easy to cancel. Together, they tell you when buying helps and when it doesn't.

1. Your discount is not the same as everyone else's

Southwest's standard price is 3 cents per point. It discounts points regularly, but not equally. One Mile at a Time reported that during a sale running September 2 to October 2, 2026, different members were offered 35%, 45%, or 50% off. Award Travel Finder's tracker, updated October 9, 2026, listed a 50% discount through October 29.

On a purchase of 60,000 points, those tiers look like this:

• 50% off: $900, or 1.5 cents per point.
• 45% off: $990, or 1.65 cents per point.
• 35% off: $1,170, or 1.95 cents per point.

The discount in that sale applied only to purchases of at least 3,000 points in one transaction.

What to do: log in and look at your own offer before you read anyone's verdict on the sale, including this one. A 50% offer and a 35% offer lead to different answers.

2. A point is worth about 1.3 cents, almost every time

With most airlines, a point's value swings widely, and experts hunt for sweet spots. Southwest is different. Frequent Miler explains that award prices depend on demand and the flight's cash price, rising and falling with the fare. Any seat for sale can be booked with points.

The result is predictable value. Frequent Miler's benchmark is 1.3 cents per point. One Mile at a Time estimates 1.1 to 1.5 cents.

That predictability works against buyers. No hidden jackpot makes points bought at 1.5 cents suddenly worth 4 cents. One Mile at a Time concludes that buying at 1.5 cents or more rarely makes sense, because points usually redeem for less.

What to do: treat buying as a way to complete a booking, not as a discount on travel.

3. Bought points do not count toward the Companion Pass

The Companion Pass lets a named companion fly with you for only the taxes. Frequent Miler requires 135,000 qualifying points in a calendar year.

Purchased points do not qualify. Neither do points transferred from another member, most bonus points, or points transferred in from hotel partners or Chase Ultimate Rewards. What does count: base points from paid flights, Southwest credit card spending, card welcome bonuses, and many partner activities.

What to do: if the pass is your target, put your money into paid flights and card spending. Buy points only for redemptions.

4. There are limits, and your card sees a different merchant

According to One Mile at a Time, you can buy up to 60,000 points per day, with no annual limit. That is unusually open. Most programs cap purchases annually.

The sale is processed by Points.com, not by Southwest. Your credit card will not record it as an airline purchase, so do not expect an airfare bonus category to apply. One Mile at a Time suggests using a card with a minimum spending requirement or one with strong everyday rewards.

What to do: choose a card for its base earning rate, and buy only what your booking needs. The lack of an annual cap isn't a reason to stock up.

5. Points bookings are easy to undo, and points never expire

This is the best argument for holding Rapid Rewards points at all.

• Cancellations. Frequent Miler notes that you can cancel award flights for no fee up to 10 minutes before departure, with points returned immediately. One Mile at a Time adds that a canceled cash ticket becomes a travel credit for a future flight, while redeposited points can be used for anyone.
• Changes. If your flight price drops after you book, Frequent Miler says changing to a cheaper fare returns the difference in points.
• Expiration. Rapid Rewards points do not expire, and no activity is needed to keep them. Closing your account forfeits them.

What to do: if your travel dates are uncertain, a points booking gives you a clean exit. After you book, check the price again periodically. If it falls, rebook and collect the difference.

So when should you buy?

• Buy when you are a few thousand points short of a flight you are ready to book. A 3,000-point top-up at 50% off costs about $45.
• Consider buying when your plans may change, and you value getting points back more than holding a travel credit.
• Do not buy to pay for a whole trip at a 35% or 45% discount, to chase the Companion Pass, or because a sale is ending. Another sale will follow.

A quick self-check

• What discount does my account show?
• What is the cash fare, and what is the points price?
• How many points am I actually missing?
• If I cancel, would I rather hold points or a travel credit?

Two more notes. Southwest offers a Cash + Points option, which Frequent Miler says yields poor value per point. And free checked bags now depend on your fare, elite status, or a Southwest credit card, so include bag costs when you compare a Southwest fare with a competitor's.
