Short answer: selling airline miles is not against the law in the United States, but it is technically against the rules of virtually every major frequent flyer and hotel loyalty program. Those are two separate questions, and most articles on this topic blur them together. Below is what each program’s own terms actually say, what happens in practice when a transaction gets flagged, and how to decide whether a sale makes sense for your balance.

We buy and sell miles for a living, so treat this as an interested party being straight with you rather than a neutral referee. Everything here links to the program terms so you can check it yourself.

Legal is not the same as permitted

There is no federal statute in the United States that makes selling frequent flyer miles a crime. People sell them, brokers buy them, and money changes hands without anyone being arrested. That is the sense in which the practice is legal.

What miles are, though, is a contractual benefit issued under a program agreement you accepted when you enrolled. Delta puts it plainly: miles are not the property of the member. You hold a revocable benefit, not an asset. So the operative question is not whether the government objects. It is whether the airline objects, and what the airline can do about it.

The airline objects. Every major program prohibits sale or barter, and each reserves specific remedies. The rest of this page is about what those remedies are.

What the major airline programs actually say

These are paraphrased from each program’s published terms as of 2026. Programs revise their rules without notice, so follow the links and read the current version before you act on anything here.

The pattern is consistent across programs, which tells you something: this is not one airline being unusually strict. Loyalty currency only holds its value for the issuer if it cannot be freely traded, so every issuer writes the same clause.

For a documented example of enforcement rather than just the rule on paper, The Points Guy reported on an AAdvantage member assessed a 500,000 mile penalty after American determined he had offered miles for sale. That is the enforcement ceiling, not the typical outcome, but it is real and it is on the record.

What your miles are worth by redemption route

Before deciding whether to sell, it helps to know what you are giving up. The same mile is worth very different amounts depending on how you use it. Here is the rough shape of it:

Two things worth sitting with. First, selling is not the highest value use of a mile; a well planned premium cabin redemption beats it comfortably. If you have the flexibility to book one, do that instead. Second, selling does beat the routes most people default to when they give up on a balance, which are merchandise, gift cards and letting the miles quietly expire.

Selling makes sense in a narrow set of circumstances: you have a balance you realistically will not use, you have looked at award availability and come up empty, and you understand and accept the account risk. If you want the longer version of that calculation, we walked through it in turning airline miles into cash and in our comparison of selling miles versus cash back credit cards.

What happens when a transaction gets flagged

Programs run fraud detection on redemption patterns. A booking for an unrelated passenger, from an unfamiliar device or IP, shortly after a period of account inactivity, is the pattern that draws attention. When something is flagged, the outcomes run roughly in this order of frequency:

1. Nothing. Most transactions are not flagged. This is the honest baseline and it is why the market exists.
2. The booking is held for review. The ticket sits unconfirmed while the program asks for documentation. Sometimes it clears.
3. The award ticket is voided. Even after issue, and sometimes after travel has begun. The passenger is told to pay the published fare or not fly.
4. Miles are deducted. The balance involved is removed, whether or not the redemption completed.
5. The account is suspended or closed. The remaining balance goes with it, along with elite status and any companion certificates.
6. A penalty is assessed. Rare, and generally reserved for members who advertised miles publicly or did it repeatedly.

Two points that people consistently get wrong. The risk sits with the account holder, not with the traveller and not with the broker, because it is the account holder’s contract with the program. And the risk does not expire at the moment you are paid; a program can act months later if it revisits a booking.

Who bears which risk in a broker deal

Any broker telling you a transaction is risk free is either misinformed or hoping you are. Here is the accurate split:

• You bear the program risk. Your account, your balance, your status. No broker can indemnify you against your airline, because no broker is a party to your program agreement.
• The broker bears the payment and delivery risk. Whether the miles arrive, whether the booking completes, whether the buyer on the other side is real.
• Payment sequencing decides who is exposed to whom. If you are paid before you transfer, the broker is carrying counterparty risk on you. If you transfer first, you are carrying it on them. Ask which way round it works before you start.

On our side, we pay upfront by PayPal before the transfer, which shifts the counterparty risk from you onto us. That is a real protection and it is the one we can actually offer. It is not protection against your airline, and we will not pretend otherwise. Our team and process are described in full, and there is more detail in our FAQ.

Five questions to ask any miles broker first

Ask these of us and of any airline miles broker else you are considering. The answers tell you more than any testimonial page.

1. Who pays first, and by what method? Vague answers here are the single biggest warning sign.
2. What is the rate per mile, in writing, before I transfer anything? A quote that shifts after you have committed is not a quote.
3. What is your registered legal entity, and where can I verify it? A brand name is not a company.
4. What happens if my account is flagged mid transaction? There should be a specific answer, not reassurance.
5. Where can I read reviews you did not write? Dated, third party, responded to. Testimonials on a broker’s own site are worth roughly nothing, including ours.

Your miles and points options, ranked honestly

From most to least value, assuming a balance you are not sure what to do with:

1. Book a premium cabin award. Two to five cents per mile or better, and zero program risk. If you can make this work, nothing else comes close.
2. Transfer to a partner program with better award pricing. Often unlocks availability your home program does not show.
3. Book economy awards for family. Permitted by every program listed above, since redeeming in someone else’s name is allowed as long as no consideration changes hands.
4. Sell through a broker. Highest cash conversion, real account risk, appropriate for balances you have genuinely written off.
5. Gift cards or merchandise. Poor value, but no risk and no effort.
6. Let them expire. Strictly worse than every option above, and the most common outcome.

If you land on option four, we handle most major programs. The busiest are Delta SkyMiles, United MileagePlus, Amex Membership Rewards, Marriott Bonvoy and Hilton Honors. The full lists are on our sell miles and sell points pages. If you are going the other direction and need miles to complete a redemption, see buy miles.

Frequently asked questions about miles and points selling in 2026

Is it illegal to sell airline miles?

No United States law prohibits it. It does breach the terms of essentially every major loyalty program, which is a contractual matter between you and the airline rather than a criminal one. The consequences are account level, not legal.

Will my account definitely get closed if I sell miles?

No. Most transactions are never flagged. But the possibility is real, the decision is entirely the program’s, and there is no appeal process worth relying on. Treat the balance as something you are prepared to lose.

Can I gift miles to someone instead?

Yes, within limits. Every program above allows you to book an award ticket in another person’s name. What is prohibited is receiving money or other consideration for it. The transfer is not the problem; the payment is.

Do I owe tax on money from selling miles?

Possibly. Miles earned from flying are generally treated as a rebate rather than income, but cash received from a sale may be reportable. We are not tax advisors, and this depends on your situation. Ask a CPA before you assume either way.

How much can I actually get?

It depends on the program, the balance size and current demand. Larger balances in programs with strong award availability command better rates. Request a quote and you will get a number in writing before you commit to anything.

What if my miles are expiring soon?

Check whether a small qualifying activity resets the clock first, since most programs restart expiry on any earning or redemption activity. That is usually cheaper than any alternative.

Before you decide

The useful summary is this: selling is legal, it is against your program’s rules, the risk is yours alone, and it is the right call only for a balance you have genuinely given up on. Anyone who tells you it is completely safe is selling you something. So are we, but we would rather you decide with the actual rules in front of you.

If you have read this and still want a number, request a quote and we will send one with no obligation. If you would rather see what other people’s experience has been first, our reviews are there.
