What an airline points credit card does
An airline points credit card earns you points or miles every time you use it to pay for something. You can then redeem those points for flights, seat upgrades, or other travel perks with the airline that issued the card. The card itself is a regular credit card — you get a monthly bill, you pay interest if you carry a balance, and your payment history affects your credit score just like any other card.
The main difference between this card and a regular rewards card is that the points stay within one airline's ecosystem. A general cash-back card gives you money or points you can use anywhere. An airline card locks your rewards to one airline, which means the points are worth more per dollar spent — but only if you actually fly that airline and can use them before they expire.
Key Takeaways
- Airline cards earn points on every purchase, but the points are only useful if you fly that specific airline or its partners.
- The sign-up bonus — often 50,000 to 75,000 points — is usually worth more than the points you earn from everyday spending.
- Annual fees range from $0 to over $500, and the card only makes financial sense if the perks you actually use cover that cost.
- Points expire if you don't use them, and airline devaluations can reduce what your points are worth without warning.
- You still pay interest on unpaid balances and build credit history the same way as with any credit card.
How the sign-up bonus works
When you open an airline card, you usually get a large bonus of points — often 50,000 to 75,000 miles — if you spend a certain amount in the first few months. This bonus is almost always the single best value you'll get from the card. A sign-up bonus of 50,000 points might be worth $500 to $750 in flight value, while you'd need to spend thousands of dollars on the card to earn that many points through regular purchases.
The catch is that you have to meet the spending requirement to get the bonus. This is usually $3,000 to $5,000 in purchases within three months. If you can't or won't spend that much naturally, the bonus doesn't happen. Some people deliberately use the card for planned expenses — a home repair, a large purchase they were going to make anyway — to hit the threshold. Others open the card and never reach the minimum, which means they paid the annual fee for nothing.
Annual fees and when they make sense
Most airline cards charge an annual fee, ranging from $0 to over $500. A $95 annual fee is common for mid-tier cards; premium cards with more perks can cost $250 or more. The card issuer is betting that the perks — free checked bags, priority boarding, seat upgrades, lounge access — will be worth more to you than the fee.
The math only works if you actually use those perks. If the card gives you a free checked bag on every flight and you fly twice a year, that's $60 in value right there. If you never check a bag, that perk is worthless. Before you open a card, list the perks it offers and honestly estimate what you'd use. If the total value is less than the annual fee, the card costs you money.
Some cards waive the first year's fee, which gives you a risk-free window to decide whether to keep it. Others credit you points equal to the fee, which softens the blow but doesn't eliminate it — those points still need to be redeemed to have value.
Earning points on everyday purchases
Once you have the card, you earn points on most purchases. The earning rate varies: you might get 1 point per dollar on general purchases, 2 or 3 points per dollar on airline tickets or dining, and bonus points on specific categories like gas or hotels. The card issuer chooses these rates to encourage you to use the card for certain types of spending.
The earning rate sounds good until you do the math. If you earn 1 point per dollar and those points are worth about 1 cent each, you're getting 1% cash back — the same as a basic cash-back card. If you earn 2 points per dollar on dining and those points are worth 1.5 cents each, you're getting 3% back on dining, which is competitive. But if points are worth less than you think, the earning rate is misleading.
This is why the sign-up bonus matters more than the ongoing earning rate. You'll earn points slowly through everyday spending, but you'll earn a huge chunk upfront, and that's where most of the card's value lives.
What points are actually worth
The value of a point is not fixed. It depends on what you're redeeming it for and when. A point might be worth 1 cent if you use it for a cheap domestic flight, or 2 cents if you use it for an expensive international flight. The same point might be worth nothing if the airline has devalued it or if you can't find an available seat at the price you want.
Airlines also change the point cost of flights without warning. A flight that cost 25,000 points last year might cost 30,000 points this year. This is called a devaluation, and it reduces the purchasing power of the points you've already earned. You have no control over this, and it happens regularly.
Because of this uncertainty, financial experts often estimate that a point is worth somewhere between 0.5 cents and 2 cents, depending on how you use it. If you're conservative and assume 1 cent per point, a 50,000-point sign-up bonus is worth about $500. If you're optimistic and assume 1.5 cents, it's worth $750. Neither number is may provide.
Points expiration and account closure
Most airlines let you keep points indefinitely as long as your account is active. An account stays active if you earn or redeem points at least once every 12 to 24 months. If you don't use your account for that long, the airline can close it and erase your points.
This matters if you're saving points for a big trip. If you earn 100,000 points and then don't fly or use the card for two years, the airline can delete them. To keep points alive, you need to use the account — either by flying, by using the credit card, or sometimes by making a small purchase through the airline's shopping portal.
Some cards offer a perk that extends your points expiration or resets the clock, but you usually have to pay extra for this or use the card regularly anyway.
Credit score impact and debt risk
An airline card is a credit card, which means it reports to the three credit bureaus and affects your credit score. Opening the card creates a hard inquiry, which temporarily lowers your score by a few points. The new account itself also lowers your average account age, which can dip your score further.
Over time, if you pay on time every month, the card helps your score by showing a long history of on-time payments and a low credit utilization ratio. But if you carry a balance and pay interest, you're paying the credit card company for the privilege of earning points. A $5,000 balance at 18% interest costs you $900 a year in interest — far more than the value of the points you earned.
The biggest risk is overspending to hit the sign-up bonus or to earn more points. If you spend money you wouldn't normally spend just to earn rewards, you've lost money, not made it. The card is only valuable if you use it for purchases you were going to make anyway.
Frequently Asked Questions
Can I use points from one airline on another airline?
Usually not directly. Some airlines are part of alliances — like Star Alliance or OneWorld — and you can sometimes transfer points between partner airlines or use them on partner flights. But points earned on an American Airlines card are locked to American unless the card issuer allows transfers, which is rare. Check the card's terms before you open it.
What happens to my points if I close the card?
Your points don't disappear when you close the card. They stay in your airline account as long as your account stays active. However, closing the card means you're no longer earning points from purchases, and if you don't use the account for 12 to 24 months, the airline can close it and erase the points. Keep the account open or use it occasionally to preserve your balance.
Is it worth opening multiple airline cards?
Some people open multiple cards to collect sign-up bonuses from different airlines. This works if you actually fly multiple airlines and can use the points. But each new card creates a hard inquiry and a new account, which temporarily lowers your credit score. If you're planning to explore for a mortgage or loan soon, opening multiple cards in a short time can hurt your chances of approval.
Can I sell my points?
Most airline terms of service prohibit selling points. Some third-party sites claim to buy and sell points, but this violates the airline's rules and can result in your account being closed and your points forfeited. The safest approach is to use points only for your own travel.
What's the difference between points and miles?
The terms are used interchangeably by most airlines. "Miles" originally referred to frequent-flyer miles earned by flying, while "points" referred to rewards from credit cards. Today most airlines call them all miles or all points regardless of how you earned them. They work the same way in your account.
