You can buy airline miles directly from most major carriers, but the price per mile varies widely and rarely makes financial sense unless you are close to a redemption you need
Most airlines sell their points directly through their website or a dedicated purchase portal. American Airlines sells AAdvantage miles, United sells MileagePlus points, Delta sells SkyMiles, and Southwest sells Rapid Rewards points. The mechanics are straightforward: you log into your account, choose how many points to buy, and pay by credit card. The airline deposits the points into your account within hours.
The real question is whether buying makes sense for your situation. Airlines price points to be most attractive when you are 5,000 to 10,000 miles short of a specific ticket you want to book. At that scale, the convenience of buying rather than waiting for credit card bonuses or earning through flights can outweigh the cost. At larger quantities — buying 50,000 miles to fill a gap — the per-mile cost becomes expensive relative to what you would pay through credit card sign-up bonuses or transfer partners.
Key Takeaways
- Airlines sell points directly through their loyalty program website, and points arrive in your account within hours of purchase.
- The cost per mile ranges from 1 cent to 2 cents depending on the airline and the quantity you buy, making large purchases more expensive than earning through credit card bonuses.
- Buying points makes the most financial sense when you are within 10,000 miles of a specific redemption and do not want to wait for earning or transfers.
- Most airlines offer modest discounts when you buy in bulk, though the per-mile cost still exceeds what you would pay through sign-up bonuses on airline credit cards.
Where to buy points and what each airline charges
Each airline operates its own points store. You access it by logging into your frequent flyer account on the airline's main website, then looking for a link labeled "Buy Miles," "Purchase Points," or "Shop" — the exact wording varies. From there you select a quantity and complete the purchase with a credit card.
The per-mile cost depends on the airline and the package size. American Airlines, for example, typically charges between 1.3 and 1.5 cents per mile when buying smaller quantities, with a slight discount for larger purchases. United and Delta operate similarly. Southwest, which uses a different redemption model based on dollar amounts rather than points, charges a flat rate per dollar of travel value. The exact prices change periodically, so checking the airline's purchase page directly is the only way to know the current rate.
Some airlines occasionally run promotions offering bonus points when you buy — for instance, "buy 10,000 miles and get 2,000 free." These promotions appear on the purchase page and are worth monitoring if you are already planning to buy, though they do not change the fundamental math of whether buying is worthwhile.
When buying points makes financial sense
The decision to buy comes down to comparing the cost of points to the value of the ticket you are trying to book. If you can book a domestic flight for 25,000 miles and that flight would cost $300 to buy with cash, then each mile is worth roughly 1.2 cents. If the airline is selling miles at 1.5 cents each, buying does not make sense — you are paying more per mile than the ticket is worth.
Buying becomes reasonable when you are very close to a redemption and the alternative is waiting weeks or months to earn the remaining miles. If you need 8,000 more miles for a ticket departing in two weeks, and you would have to take a detour flight or wait for your next credit card bonus to reach that threshold, buying those 8,000 miles might be worth the extra cost for the convenience and certainty.
The worst use of buying points is to fill a large gap — say, needing 40,000 miles and having none. In that scenario, you would almost always come out ahead by explore for the airline's credit card, which typically offers a sign-up bonus of 50,000 to 75,000 miles plus ongoing earning. Even accounting for the annual fee, the cost per mile through a sign-up bonus is far lower than buying directly.
How buying points interacts with credit card bonuses and transfers
If you hold an airline credit card, you earn points on every purchase and can often transfer points from partner credit cards or travel platforms. These earning paths are almost always cheaper per mile than buying directly. A sign-up bonus on an airline card might give you 60,000 miles for spending $5,000 in three months — a cost of roughly 0.08 cents per mile when you factor in the value of the spending you were going to do anyway.
Transfer partners — credit card programs like Chase Ultimate Rewards or American Express Membership Rewards — sometimes offer transfer bonuses to airline programs. These bonuses effectively reduce the cost per mile you are transferring. Buying points bypasses all of these cheaper routes, so it only makes sense if you have exhausted or cannot use those options.
The tax and account implications of buying points
Points you buy are not taxable income — the IRS treats them as a purchase, not a gift or prize. You pay for them with after-tax dollars, and there is no tax form or reporting requirement when you redeem them later.
One account rule to know: if your frequent flyer account has been inactive for a certain period (usually 12 to 24 months depending on the airline), the airline may close it or expire your points. Buying points does not reset this clock on all airlines. Check your specific airline's policy before buying points into an account you have not used recently, as you could lose them if the account is closed for inactivity.
Alternatives to buying if you are short on points
Before buying, consider whether you can reach your goal through other means. If you have a credit card from the airline or a transfer partner, you might be able to move points into your account within days. If you have a flexible rewards card like the Chase Sapphire Preferred or American Express Platinum, you can transfer those points to the airline at a 1:1 ratio, often with a transfer bonus that increases the value.
Another option is to book a lower-tier ticket now and upgrade later using points or cash, rather than waiting to accumulate enough points for the ticket you want. Some airlines allow you to hold a reservation for a limited time while you earn or buy the remaining points needed.
If the gap is very small — fewer than 5,000 miles — you might also check whether the airline offers any promotional ways to earn points quickly, such as shopping through their online mall or completing surveys.
Frequently Asked Questions
Can I buy points for someone else's account?
No. You can only buy points into an account you own. Some airlines allow you to transfer points to a family member or friend after they are in your account, but you cannot purchase directly into another person's account. Check your airline's transfer policy to see if you can move points after buying them.
What happens if I buy points and then the airline devalues them?
Airline devaluations are common — redemption rates change, award charts are updated, and the number of miles required for a seat increases. Points you have already bought are subject to these changes just like points you earned. There is no refund or compensation if the airline changes its redemption rates after you purchase.
Is there a limit to how many points I can buy?
Most airlines set a purchase limit per transaction or per year, though the limits are high enough that most people never hit them. American Airlines, for example, allows you to buy up to 100,000 miles in a single transaction. Check your specific airline's purchase page for its current limits.
Do points I buy expire differently than points I earn?
No. Once points are in your account, the airline treats them the same regardless of how you got them. They are subject to the same expiration policies and inactivity rules as earned points. If your account goes inactive, both types of points may expire together.
Can I use a debit card or bank transfer to buy points?
Most airlines require a credit card for point purchases. Some may accept debit cards, but this varies by airline and payment processor. Check the payment options on your airline's purchase page, or contact the airline directly if you do not have a credit card available.
