The best airline card depends on which airline you fly most and how you spend money
There is no single "best" airline credit card because the value you get depends on where you fly and what you spend on. A card that rewards you heavily for flights on United might give you almost nothing if you fly Southwest. The card that earns the most points per dollar on airfare might have an annual fee that wipes out your gains if you don't fly often enough. Start by looking at which airline you actually use — not which one you think you should use — and then match the card's rewards structure to your real spending pattern.
The major U.S. carriers all issue their own branded credit cards through partnerships with banks like Chase, American Express, and Citi. Each card comes with different earning rates, annual fees, and perks like free checked bags or priority boarding. Some cards are worth the fee only if you fly that airline at least a few times a year. Others have benefits that pay for themselves even if you rarely fly.
Key Takeaways
- The card that works best for you depends on which airline you fly most often and whether you'll use the annual fee benefits like free checked bags or seat upgrades.
- Most airline cards earn 2 to 5 points per dollar on airline purchases and 1 point per dollar on everything else, but the annual fee typically ranges from $95 to $550.
- A card's sign-up bonus — often 50,000 to 75,000 points — can be worth $500 to $1,000 in flight value, but only if you meet the spending requirement within the timeframe given.
- Cards from smaller airlines like Southwest or Alaska often have lower annual fees and simpler earning structures than cards from major carriers.
- Your existing credit score affects which cards you can get approved for and what interest rate you'll pay if you carry a balance.
How airline card rewards actually work
Airline credit cards earn points (or miles, depending on the airline's name for them) that you can redeem for flights, seat upgrades, or baggage fees. The earning rate is usually highest on purchases from that airline — typically 2 to 5 points per dollar — and lower on everything else, usually 1 point per dollar. Some cards also earn bonus points in specific categories like dining or gas.
The catch is that points don't have a fixed dollar value. A point might be worth 1 cent on a cheap flight or 2 cents on an expensive one, depending on the route and how far in advance you book. This means a card that looks generous on paper might not deliver the same value to everyone. If you book flights months ahead on off-peak routes, your points go further. If you book last-minute peak flights, you'll burn through points faster.
Most airline cards also come with a sign-up bonus — often 50,000 to 75,000 points if you spend a certain amount (usually $3,000 to $5,000) within the first few months. This bonus is often the real money-maker. A 50,000-point bonus might be worth $500 to $1,000 in flights, but only if you can meet the spending requirement without overspending just to get the bonus.
Annual fees and what they actually cover
Airline credit cards charge annual fees ranging from $95 to $550, depending on the card and the airline. The fee is charged every year, usually on your card anniversary. Before you dismiss a card because of the fee, look at what it includes — the benefits often pay for themselves if you use them.
Most cards include a free checked bag for you and one companion on flights with that airline. A checked bag typically costs $35 to $40 per flight, so if you fly round-trip twice a year, that benefit alone is worth $140 to $160. Many cards also include priority boarding, which lets you board earlier and keep a carry-on bag at no charge. Some premium cards add benefits like annual travel credits, lounge access, or statement credits for incidental fees like seat selection.
The question to ask yourself is whether you'll actually use these benefits. If you fly that airline only once a year and pack light, a $95 annual fee might not be worth it. If you fly four times a year and always check a bag, the fee pays for itself in checked bag savings alone.
Comparing the major U.S. airline cards
| Airline | Card Name (Issuer) | Annual Fee | Earning Rate (Airline) | Sign-Up Bonus Range |
|---|---|---|---|---|
| American Airlines | AAdvantage (Citi) | $95–$450 | 2–3 points per $1 | 50,000–75,000 miles |
| Delta | SkyMiles (American Express) | $95–$550 | 2–3 points per $1 | 50,000–75,000 miles |
| United | MileagePlus (Chase) | $95–$525 | 2–4 points per $1 | 50,000–75,000 miles |
| Southwest | Rapid Rewards (Chase) | $69–$99 | 2–3 points per $1 | 40,000–60,000 points |
| Alaska Airlines | Visa (Bank of America) | $75–$195 | 2–3 points per $1 | 40,000–50,000 miles |
American Airlines, Delta, and United all have multiple card tiers, with higher annual fees unlocking more benefits. The entry-level cards from these carriers typically charge $95 and include a free checked bag and priority boarding. Premium versions charge $450 to $550 and add benefits like annual travel credits, lounge access, and higher earning rates.
Southwest and Alaska have simpler card lineups with lower annual fees. Southwest's card costs $69 to $99 and includes two free checked bags (a major advantage if you travel with luggage). Alaska's card starts at $75 and includes a free checked bag plus a 50% discount on additional bags for companions.
When a sign-up bonus is actually worth pursuing
A sign-up bonus can be the best reason to open an airline card, but only if you meet two conditions: you can hit the spending requirement without overspending, and you'll actually use the points you earn.
Most sign-up bonuses require you to spend $3,000 to $5,000 within the first three months. If you're already planning to spend that amount on flights, groceries, and other regular purchases, the bonus is essentially information programs. If you'd have to change your spending habits or make unnecessary purchases to hit the threshold, the bonus isn't worth it — you'll pay more in interest or overspending than the bonus is worth.
The second condition is harder to measure but just as important. A 50,000-point bonus is only valuable if you'll actually book a flight with those points. If the points sit unused because you don't fly that airline often enough, or because you're waiting for a "better" redemption that never comes, the bonus has no real value to you.
How your credit score affects which card you can get
Airline credit cards typically require a good to excellent credit score — usually 670 or higher, though some premium cards want 750 or higher. If your score is lower, you may not be approved, or you may be approved with a lower credit limit or higher interest rate.
Before you explore, check your credit score through a free service like AnnualCreditReport.com (the only federally authorized site for free credit reports) or through your bank or credit card issuer if they offer it. If your score is below 670, you might want to focus on building credit before explore for an airline card. Opening a card you won't be approved for can lower your score temporarily because the hard inquiry stays on your report for two years.
If you're approved, remember that the rewards only matter if you don't carry a balance. Airline cards typically charge 18% to 24% interest on unpaid balances. If you pay interest, you'll erase the value of any rewards you earn.
Alternatives if you don't fly one airline consistently
If you fly different airlines depending on price or schedule, an airline-specific card might not be the best fit. A general travel rewards card — like the Chase Sapphire Preferred or American Express Gold — earns points that work across multiple airlines and can often be transferred to airline partners at a 1:1 ratio. These cards typically charge higher annual fees ($95 to $250) but offer more flexibility.
Another option is a cash-back card that gives you a percentage back on all purchases. You won't earn airline miles, but you'll get a fixed dollar value that you can use however you want — including buying airline tickets at full price if you choose. Cash-back cards often have lower annual fees or no annual fee at all.
If you fly infrequently, you might skip a branded card entirely and use a general rewards card instead. The flexibility usually outweighs the higher earning rate on airline purchases, especially if you'd pay an annual fee you don't fully use.
Frequently Asked Questions
Can I use airline miles from one airline on another airline?
Not directly — miles earned on an American Airlines card can only be used for American Airlines flights. However, some cards let you transfer miles to airline partners. Check the card's terms to see which airlines accept transfers. Some premium cards also let you book partner airlines through the main airline's website using your miles.
What happens to my miles if I close the card?
Your miles stay in your airline account and don't disappear when you close the card. However, some airlines have policies that devalue or remove miles if your account is inactive for a set period (usually 12 to 24 months). Keep your account active by earning or redeeming miles occasionally, even if you're not using the card.
Is it worth opening multiple airline cards to get multiple sign-up bonuses?
It can be, if you fly multiple airlines and can meet the spending requirements without overspending. Opening multiple cards in a short time will lower your credit score temporarily, but the score usually recovers within a few months. Space out applications by at least three months to minimize the impact. Only do this if you'll actually use the miles you earn.
Do airline miles expire?
Most U.S. airlines don't expire miles as long as you have some account activity — earning or redeeming miles, or even just logging into your account. However, policies vary by airline. Check your airline's specific policy. Some airlines expire miles after 18 to 24 months of inactivity, while others don't expire them at all.
What's the difference between points and miles?
The terms are used interchangeably by most airlines. Southwest calls them "points," while American, Delta, and United call them "miles." The mechanics are the same — you earn them on purchases and redeem them for flights or other rewards. The value per point or mile varies by airline and redemption.
