Cheapest Airline Miles to Buy Right Now (2026)

What are the cheapest airline miles to buy right now?

The cheapest airline miles come from sellers on the secondary market, where per-mile prices run far below what airlines charge to buy miles directly. On the MileMarketplace price index, live prices in June 2026 ranged from about $0.006 to $0.020 per mile, averaging roughly $0.016 across 19 programs. By comparison, buying miles straight from most airlines costs around 3 cents each — so the marketplace is often half the price or less.

The single cheapest program shifts daily as sellers list and adjust, which is why a live ranking beats a static 'best programs' list. If you want to skip the theory, you can browse miles by program sorted cheapest-first and see the current floor for any airline in seconds.

How much do airline miles cost to buy?

Airline miles cost roughly $0.006 to $0.020 per mile on the secondary market, or about $6–$20 per 1,000. The exact price depends on the program and how many sellers are competing. Volume discounts are common, so buying a larger block usually lowers your per-mile rate. That range is what real buyers paid on MileMarketplace in June 2026 — a marketplace-derived figure, not a list price.

Buying directly from an airline is a different market entirely. Airlines price purchased miles as a revenue product, typically around 3 cents each and sometimes higher, occasionally discounted during promotions. The secondary market undercuts that because the seller already earned the miles and only needs to beat what other sellers are asking.

Why are marketplace miles cheaper than buying from the airline?

Marketplace miles are cheaper than buying from the airline because of who is selling and why. When an airline sells you miles, it sets the price to capture most of the redemption value — there is no competition, so the rate stays near 3 cents. When members sell miles on a marketplace, they are offloading a currency they already hold and competing against other sellers, which pushes per-mile prices down toward 1 to 1.5 cents. As a buyer, you capture the gap between the airline's retail rate and what a member will accept.

How much does it cost to buy miles directly from an airline?

Buying miles directly from an airline typically costs around 3 cents per mile, and the all-in cost can climb higher once taxes and fees are added. Airlines run frequent 'buy miles' promotions with bonus miles that lower the effective rate, but even a strong promo rarely beats a competitive secondary-market price. The reason to buy direct is usually convenience or topping off a balance instantly — not price. For the lowest cost per mile, the marketplace almost always wins.

Cheapest by program: the live snapshot

The cheapest program is whichever has the lowest active listing right now, which is why the ranking is published live rather than fixed. In the June 2026 snapshot, hotel currencies like IHG One Rewards sat at the very bottom ($0.006 per mile), while flexible airline programs such as Aeroplan and Avios clustered around $0.015. The full, current ranking lives on the miles price index.

• Cheapest overall: hotel and bank points often dip below $0.01 per mile.
• Cheapest flexible airline miles: Aeroplan, Avios, Flying Blue tend to sit around $0.015.
• Mid-range: Cathay, KrisFlyer, United around $0.016–$0.017.
• Top of range: American, Lufthansa around $0.020 — still well below airline retail.

Why cheapest isn't always the best value

The cheapest miles are only a deal if you can redeem them well — a low per-mile price on a program with no award space for your route is worthless. Value depends on three things together: the price you pay, whether the program has the seat you want, and what that seat costs in cash. A slightly pricier mile in a program that actually has your business-class award open beats a rock-bottom mile you can never use.

Match the program to a confirmed award seat first, then buy the cheapest miles in that program. Use are airline miles worth buying to run the all-in math before purchasing.

How to tell if cheap miles are actually a good deal

Cheap miles are a good deal when your all-in cost — the price of the miles plus the cash taxes — is clearly below the cash fare for the same seat. Run the same comparison every time, and the answer is obvious.

Which cheap miles are the most useful?

The most useful cheap miles are flexible currencies with premium-cabin sweet spots, because they convert a low purchase price into a high-value redemption. Aeroplan, Avios, Flying Blue, and KrisFlyer repeatedly show up as buyer favorites for exactly this reason: they are inexpensive to acquire and book outsized value in business and first class. Buying cheap miles in a program with no good sweet spots just gets you a cheap currency you struggle to spend.

Can you buy airline miles below 1 cent per mile?

Yes — some hotel and bank points, and occasional discounted airline listings, sell below $0.01 per mile. In the June 2026 snapshot, IHG One Rewards listed from about $0.006 per mile. Sub-penny pricing is most common in currencies that are easy to earn and harder to redeem at top value, so always confirm you can redeem that currency for the trip you want before buying purely on price.

When buying cheap miles is a mistake

Buying cheap miles is a mistake when you buy before confirming award space, when you buy for cheap economy fares, or when you buy a currency you cannot redeem well. Speculative buying — purchasing a balance and hoping space appears — is how buyers end up stuck with miles they overpaid to acquire and cannot use. The discipline is simple: confirm the seat, price the exact award, then buy only what that booking needs.
