Airlines and hotel chains constantly run promotions offering to sell you loyalty points directly, often at a 20-40% bonus over the standard purchase price. It’s tempting to dismiss these offers outright since points bought with real money almost always cost more per point than points earned through spending or transfers. But there are specific, narrow situations where buying points is a genuinely smart move rather than a marketing trap. The trick is knowing how to run the math before you click “buy.”
The Baseline Math You Need First
Every buy-points decision comes down to one comparison: cost per point versus value per point. If Delta sells SkyMiles at 3.2 cents each during a bonus promotion and you can reliably redeem those miles for 1.5 cents of flight value on average, buying is a losing trade every time. But if you’re topping off an account to book a specific award seat you’ve already priced out at 2.5 cents per mile in value, and the purchase price works out to 1.8 cents per mile, that’s a clear win.
Work out your cost per point first: take the total price after any bonus, divide by total points received. Compare that number to the redemption value you’re actually targeting, not some generic “average” value you read online. Generic averages hide huge swings between a domestic economy redemption (often poor value) and a business-class award to Asia or Europe (often excellent value).
Scenario 1: Topping Off for a Specific Award
This is the single best use case for buying points. You’ve found a business-class award seat, you’re short by a small amount (say, 8,000-15,000 points), and the program lets you buy just enough to complete the booking. Airlines routinely charge more per point for small “gap-filling” purchases, but even at that inflated rate, spending around $250-350 to unlock a $3,000+ flight is a clear win.
The rule of thumb: only top off when you already have the award seat identified and on hold (or you’re confident it will still be available when you complete the purchase). Never buy points speculatively hoping you’ll find a good redemption later — programs devalue, award charts change, and unused purchased points are dead money.
Scenario 2: Transferable Currency Bonus Sales
Chase Ultimate Rewards, Amex Membership Rewards, and Capital One miles occasionally run purchase bonuses of their own, separate from airline-specific sales. Because transferable points can move to 10+ airline and hotel partners, a purchase here has more optionality than buying a single airline’s miles outright. If you already hold a card that earns one of these currencies and you have a specific high-value transfer partner redemption in mind (a sweet-spot business class award, for example), a well-timed bonus purchase can make sense at the margins.
Even so, treat this the same as airline point buying: identify the exact redemption first, calculate cents-per-point cost versus value, and only proceed if the gap is favorable by a meaningful margin — not a rounding error.
Scenario 3: Hotel Points for a Long Stay
Hotel points are usually worse value than airline miles on a per-point basis, but hotel loyalty programs sometimes offer 40-50% purchase bonuses that shift the math. If you’re planning a week-long stay at a property where the cash rate is high (think $300+/night) but the points cost is fixed regardless of cash price, buying points to cover a stay that would otherwise burn through a huge cash outlay can work — especially for aspirational properties where award nights are priced favorably relative to cash.
When Buying Points Is Almost Never Worth It
- Building a balance with no plan. Points sitting in an account with no redemption target are a bet on future award availability and program stability — a bad bet given how often programs devalue.
- Domestic economy redemptions. These rarely return more than 1-1.3 cents of value per point, well below what most purchase promotions cost.
- “Because it’s on sale.” A 30% bonus on points you have no use for is still a 100% loss if you never redeem them for more than you paid.
Quick Reference: Buy or Skip
| Situation | Buy Points? | Why |
|---|---|---|
| Topping off for a confirmed award seat | Yes | Known redemption value beats purchase cost |
| Transferable points bonus, no target redemption | No | Speculative — value depends on future availability |
| Building a balance “just in case” | No | Programs devalue; unused points lose value over time |
| Hotel points for a long stay at a pricey property | Maybe | Only if cash-vs-points gap is large and bonus is strong |
| Domestic economy flight already cheap in cash | No | Redemption value rarely clears the purchase cost |
FAQ
Is there a purchase bonus threshold worth waiting for?
Most frequent flyer programs’ best purchase bonuses land in the 30-40% range. Below 20-25%, the math rarely works even for targeted redemptions, since standard purchase prices are already inflated well above typical point values.
Can I get a refund if I buy points and the award seat disappears?
Almost never. Most programs classify point purchases as final sale. This is exactly why you should only buy after confirming the award is genuinely available and bookable, not while it’s still tentative.
Do credit card portals ever offer better rates than buying direct from the airline?
Occasionally, transferable-point portals run their own promotions that beat an airline’s standalone sale. It’s worth comparing both before committing, especially since transferable points keep more redemption options open if your original plan falls through.
Should beginners bother with buying points at all?
Not until you’re comfortable pricing out award redemptions and comparing them to cash fares. Buying points is an advanced tactic that only pays off when you already know exactly what you’re redeeming them for.
