Seven airline currencies, ranked by what their miles and points actually return in 2026 — American Airlines AAdvantage at the top of the data-backed estimates, Air Canada Aeroplan at the bottom.
The ranking is real, but the number behind each currency is an estimate, not a published rate. Conservative expert valuations and algorithmic datasets disagree, sometimes by half a cent per point. Use the order to decide what to accumulate; use the methodology to decide how much to trust it.
Ask three points-and-miles publishers what a single AAdvantage mile is worth and you will get three different numbers. All defensible. All published. None of them official.
That is the uncomfortable part of choosing a loyalty currency. There is no central bank for airline miles — no program posts a redemption rate the way a bank posts an exchange rate. What exists instead is a small industry of estimates, and the estimates disagree by margins wide enough to change which card you should be holding.
This list ranks seven currencies by the strongest 2026 figures available, then shows where each number came from and what would have to move for it to change. It is written for the traveler deciding where to route spend, not for the collector chasing a leaderboard.

How cents per point actually works
The metric everyone quotes is cents per point, or CPP. The arithmetic is not complicated: take the cash ticket price after taxes and fees, divide it by the miles required, then multiply by 100. A $600 fare booked with 40,000 miles returns 1.5 cents per mile.
What makes CPP slippery is that the inputs are chosen, not fixed. Which routes get sampled, how far ahead the booking is made, whether the sample is economy or premium cabin — each choice moves the answer.
For its October 2026 airline figures, NerdWallet compared cash and award prices on the same flights across thousands of round-trip economy searches, booked 15, 60, 90, and 180 days before departure. The Points Guy takes a different route: it blends expert judgment with trimmed averages drawn from Points Path searches, then rounds the result to the nearest five-hundredths of a cent.
Neither is an official program rate — the most useful thing to understand before reading any ranking, including this one.
Three inputs do most of the moving. Partner networks widen or narrow what a balance can actually buy.
Cabin matters enormously — a premium-cabin award can return several times what an economy redemption does, which is why a program’s average can sit well above its median. Accrual is the quiet one: how hard a balance is to build is a separate question from what it redeems for.

1. American Airlines AAdvantage — 1.7 cents per mile
1.7 cents per mile in the October 2026 data-backed set, against a conservative 1.5 cents.
AAdvantage tops both camps, which is rarer than it sounds. The two figures differ because they answer slightly different questions — one samples what economy awards actually cost against cash, the other blends premium-cabin and domestic redemptions into a single number. What holds AAdvantage at the top is breadth: a wide partner network gives the balance more places to go, and more places to go means more chances to find an award that beats the cash fare.
2. Alaska/Hawaiian Atmos Rewards — 1.4 cents per point
1.4 cents per point in the data-backed set, against a conservative 1.5 cents.
Atmos is the newest name here and the hardest to value, because it is the combined Alaska and Hawaiian currency. It sits second on the data-backed ranking and first on the conservative one — a reversal that says more about method than about the program itself.
3. JetBlue TrueBlue — 1.4 cents per point
1.4 cents per point, tied with Atmos on the data-backed side.
TrueBlue is the reminder that a ranking measures the value of a redemption, not the odds of finding one. A smaller route network means fewer places to spend the balance, so a strong cents-per-point figure can still leave you holding points you cannot use on the trip you actually want to take.
4. Avianca LifeMiles — 1.3 cents per mile
1.3 cents per mile — mid-table, and one of the more accessible currencies on this list.
Most US travelers never hold LifeMiles directly. They reach it through flexible-point transfers, which NerdWallet counts at 1:1 for this program. That matters: a currency you can top up from a card you already carry behaves very differently from one you have to fly to earn.
5. Delta SkyMiles — 1.2 cents per mile
1.2 cents per mile, tied with United.
SkyMiles is also a 1:1 transfer destination for flexible points, which softens the middling headline number. The catch is the same one that applies everywhere on this list: transfer access raises the ceiling on what a balance can do, but it does not raise the floor on what any single award will return.
6. United MileagePlus — 1.2 cents per mile
1.2 cents per mile, level with Delta.
Two large domestic programs landing on the same figure is less a coincidence than a convergence: the same economy-focused method, applied to two similar domestic networks, lands in the same place. Neither has a verified conservative estimate in the retrieved material, so the table leaves those cells open rather than guessing.
7. Air Canada Aeroplan — 1.1 cents per point
1.1 cents per point — last on the data-backed ranking.
Last place here is a statement about economy redemptions, not about the program’s ceiling. The ranking says nothing about how easily Aeroplan‘s awards can be found or how far a balance stretches in a premium cabin.
How we picked
Items are ranked by the strongest 2026 data-backed estimates available, with conservative expert figures shown beside them where a comparable number exists. Five of the seven programs have no verified conservative estimate, so those cells are marked unverified rather than filled in. Figures confirmed as of October 2026.
What this means for you
A high published CPP is worth nothing without award space to book. Choose a currency whose routes and partners match the trips you actually take, and treat the ranking as a tiebreaker rather than the deciding vote.
When you weigh a specific redemption, put a conservative estimate next to a data-backed one, and check whether the sample behind it covers economy only or premium cabins as well. Then run the numbers yourself: take the cash price, strip out taxes and fees, divide by the miles required, and compare the result with what the same paid ticket would have earned in miles and card rewards.
Two things stay unmeasured. No source in the research puts a number on how co-branded sign-up bonuses move a program’s average redemption value. That is a real gap in every published valuation: a 50,000-point welcome offer changes what a balance costs you, but not what it redeems for.
The same goes for the rewards you give up by redeeming instead of paying cash. No source sets a universal figure for that, because it depends on the itinerary, the fare, the carrier, and the card in your wallet.

Key terms
- Cents per point (CPP)
- Cents per point is the standard measure of what an airline mile or point returns when it is redeemed, worked out by dividing the cash price of a ticket by the miles required and multiplying by 100. Because the inputs are chosen rather than fixed — which routes are sampled, how far ahead the booking is made, whether the sample is economy or premium cabin — published figures vary by publisher and method. No program posts an official CPP rate, so every number in this ranking is an estimate built by comparing cash fares against award prices.
- Flexible points
- Flexible points are credit-card reward currencies that can be moved to more than one airline or hotel program instead of being locked to a single brand. NerdWallet counts many standard transfers at 1:1, among them Air France-KLM Flying Blue, Delta SkyMiles, British Airways Avios, Air Canada Aeroplan, Singapore Airlines KrisFlyer, and Avianca LifeMiles. Because this ranking measures what a balance redeems for rather than how easily it is built, a program’s transfer partners can matter as much as its headline number when deciding where to route spending.
- Award space
- Award space is the availability of a seat that can actually be booked with miles on a given flight and date. A program’s published cents-per-point figure is calculated from awards that were found and priced, so it says nothing about how often a seat is open on the route a traveler wants. That is why a strong number can still leave a balance unusable: the value of a redemption and the odds of finding one are separate questions.
- Miles + Cash
- Miles + Cash is a redemption option that lets a traveler cover part of a ticket with miles and pay the rest in cash. It is a fixed-value use rather than an award seat, so the return is set by the program rather than by the cash fare on a specific flight. Atmos Rewards offers it, and because the rate is fixed it sets a floor on what a balance is worth rather than a ceiling — the same points can return several times more on a partner premium-cabin award.
Questions? Answers.
What are American Airlines miles worth?
Two 2026 estimates put them at 1.5 and 1.7 cents per mile. Supapoints’ conservative comparison values AAdvantage at 1.5 cents, while NerdWallet’s October 2026 economy dataset puts it at 1.7. Neither is an official program rate — both are estimates built by comparing cash fares against award prices.
Is it better to use points or pay cash?
There is no universal answer, and no retrieved source puts a single number on the mileage and card rewards you give up when an award replaces a paid ticket. Work it out per itinerary: subtract taxes and fees from the cash price, divide by the miles required, then weigh that against what the paid ticket would have earned.
Can you pay for a flight with both miles and cash?
Yes — Atmos Rewards offers Miles + Cash, but it is one of the weaker uses of a balance. Those redemptions are described as returning roughly 0.5 to 0.7 cents per point, well below what the same points return on a partner premium-cabin award.
Where can I buy airline miles for the cheapest price?
The retrieved material does not rank mile-purchase prices by source, so no cheapest option can be named from it. What it does show is that a mile’s return depends entirely on how it is spent, which is why the ranking above measures redemptions rather than purchases.
