Can You Sell Airline Miles? Is It Against The Rules, Illegal, Or What?

Airline miles (and other rewards points) have increasingly become a currency, given how fervently some people collect them, and what great rewards they can unlock. I know I value miles immensely, and even assign values to each individual points currency.

However, unlike other currencies, buying, selling, or bartering miles is generally prohibited. In this post, I’d like to take a closer look at that, especially in light of the fact that buying & selling miles is a pretty common practice, which might lead people to think that it’s not a problem.

Selling miles isn’t illegal, but does violate program rules

Let me start by adding the disclaimer that I’m not a lawyer, so don’t take this as legal advice. Instead, I’m just someone who understands travel loyalty programs pretty well. As a general rule of thumb (and I’m sure there are some jurisdictions where there’s more nuance to this):

• Selling airline miles isn’t illegal, in the sense that there generally aren’t laws explicitly prohibiting this practice
• Selling airline miles almost always violates the terms & conditions of loyalty programs, which you agree to when you join

Purely as an example, here are the American AAdvantage terms & conditions regarding this:

Except for transfers as expressly permitted via your AAdvantage® account, you may not, at any time, purchase, transfer, sell, advertise for sale, or barter (including by means of transferring, gifting, or promising) any AAdvantage® Rewards and Benefits associated with the offering of any American Airlines products or services for any purpose whatsoever, such as in exchange for payment or in support of a business, product or charity or participation in an auction, sweepstakes, raffle or contest. Any such AAdvantage® Rewards and Benefits are void if transferred for cash or other consideration. Violators (including any passenger who uses a purchased or bartered award ticket) may be liable for damages and litigation costs, including American Airlines’ attorneys’ fees incurred in enforcing this rule.

I think there are a few important things to emphasize here:

• It’s not just buying & selling miles that violates rules, but really any sort of bartering activity, including offering someone miles in support of a business or even charity (so you can’t offer miles as the reward in a charity raffle)
• If you’re caught violating rules, you won’t just have your loyalty program account shut down, but you’ll potentially be liable for damages, litigation costs, and more
• Keep in mind that airlines own the miles that are in your account, so your account can be closed for any reason at the company’s discretion; in other words, American Airlines could choose to confiscate your miles even without proof that you bartered your miles

Regarding the last point, many people will probably find it wild that we don’t really “own” our miles, but keep in mind the upside to that — at least in the United States, it also generally means that miles aren’t taxable.

How risky is it to sell your miles to others?

The above are the rules, but how closely are accounts monitored in practice? Let me emphasize that I don’t personally barter miles, as the stakes are too high, and I get plenty of value maximizing miles as is. I do often gift miles to family members (no strings attached), as planning luxury travel for family is one of my love languages. I get a lot of joy out of it.

That being said, in practice can you get away with selling miles? If you’re selling miles through strangers on the internet, that’s extremely risky. Airlines have gotten really good about monitoring suspicious activity in accounts, so if you’re redeeming miles for many different people with different last names or large quantities of miles for others, airlines may watch especially closely. Airlines even often respond to online ads selling miles so that they can shut down accounts. Doing something like that is high risk.

Of course there are other situations that violate the rules just as much, but are lower risk. For example, if you book tickets for a sibling and they buy you dinner a dozen times to repay you for it, that’s going to be tough for the airline to crack down on. It violates the rules just as much, but it’s harder to prove. Again, I’d advocate against selling miles, but I still figured I’d address the questions people could have.

Lastly, I think it’s important to emphasize that sometimes auditing folks at airlines are overzealous, and incorrectly accuse people of selling miles. This can be rather problematic, because like I said above, you don’t actually own the miles in your account.

If your frequent flyer account is audited or mileage ticket is suspended, it’s not necessarily that you’re “innocent until proven guilty,” as you might otherwise be, if accused of something. Unfortunately airlines have a lot of power there, and sometimes they don’t use that power very carefully.

Are there ways to legitimately barter miles?

Airlines will typically let you pay to transfer miles between accounts, though it doesn’t typically represent a good value unless you’re trying to “top off” an account for the purpose of redeeming an award ticket. For example, some airlines may charge around one cent per transferred mile, which is only marginally less than I value most mileage currencies.

In some cases, loyalty programs also allow points pooling, so that’s a good way to share points with others. However, regardless of which method you use, getting compensated in exchange for transferring miles would still violate the rules, so you’re not actually being any more “legitimate.”

Note that some loyalty programs will let you convert your rewards into other currencies. More often than not, this doesn’t represent a great deal, but instead, it’s for those who really struggle to use the “native” currency. In these situations, there’s an agreement between the travel brands, and often it’s facilitated by points.com, which works with a variety of loyalty programs. Generally, I’d only view that as a sort of last resort redemption option, though.

How to be strategic with your points accrual

There are a few reasons that people find themselves in a situation where they’re even looking to sell airline miles, so let me provide some general tips to hopefully avoid this to begin with:

• In general, I don’t recommend earning airline miles for your credit card spending; rather, consider earning cash back or transferable points currencies, as both of those give you a lot more flexibility than an individual mileage currency
• If you’re trying to sell miles because they’re expiring soon, keep in mind there are often ways to extend their validity; often you can just make a simple purchase through an airline shopping portal, or donate 1,000 miles to charity, and that may reset the expiration of your account
• If you’re earning miles through flying, be strategic about the airline you credit your miles to, as it doesn’t have to be the same airline you’re actually flying; for example, if you live in Dallas but take a single trip on Alaska Airlines, you could also credit your miles from that flight to American AAdvantage instead of Alaska Mileage Plan, for more flexibility
• Absolute worst case scenario, you can generally redeem miles for merchandise; you’re usually not going to get a great rate of return that way, but it’s better than nothing

Bottom line

Selling airline miles generally isn’t explicitly illegal, but it does violate the rules of virtually every loyalty program. Nonetheless, this is a huge industry, and there’s no denying that a lot of people engage in this. Airlines have gotten smarter over time in identifying accounts with risky behavior, and often they’ll even take it too far. This isn’t a practice I recommend engaging in, both because it violates the rules, and because there’s significant risk.
