Loyalty programs want redeeming points to feel like magic — "free flight!" — but points are a currency, and currencies have exchange rates. Some redemptions are genuinely great value. Others are worse than just paying cash. The only way to tell the difference is to check the rate before you book.
The formula
It's one calculation:
Once you have that number, compare it to what the points are generally worth. As a rough baseline, most major airline and flexible travel points are worth somewhere in the range of 1–2 cents each when redeemed reasonably well. Below that range, you're often better off paying cash and keeping the points for a better use. Meaningfully above that range — redemptions worth 3+ cents per point — are the ones worth prioritizing.
A worked example
Say a flight costs $600 cash, or 40,000 points plus $11.20 in taxes.
- Value you're extracting: $600 − $11.20 = $588.80
- Divided by 40,000 points = 1.47 cents per point
That's a solid, roughly-fair-to-good redemption — worth using points for, especially if the cash price is high (like a last-minute or premium-cabin fare, where points redemptions often hold their value better relative to cash).
Where the math usually breaks down
- Cheap cash fares. If cash is already $150–200, points redemptions often work out under 1 cent each — a bad trade unless you have points you're not otherwise using.
- "Free" domestic economy redemptions. These are the most commonly advertised and often the weakest value, since domestic economy cash fares are already low.
- Fixed-value or portal-only redemptions. Some programs let you redeem points at a flat rate (e.g., 1 cent each) toward any travel booked through their portal. That flat rate is your floor — anything below it in a "bonus chart" isn't worth choosing over just cashing out.
When points clearly win
- Premium cabins — business and first class redemptions frequently land at 3–6+ cents per point of value, because cash prices for those seats are disproportionately high.
- Last-minute bookings — cash fares spike close to departure; award pricing (on programs that don't also spike) can stay flat, sometimes dramatically out-valuing cash.
- Peak travel periods — similar logic; if cash prices surge for holidays, a fixed award chart can become a great deal by comparison.
The takeaway
Don't redeem on autopilot. Run the cents-per-point math first — it takes under a minute — and only use points when the number clears roughly 1.5–2 cents. Save the points for the premium-cabin or peak-season booking where they'll actually outperform your credit card.
