5 Airline Miles Cards vs Cash Payback 2024

In 2024, The Points Guy identified seven co-branded airline credit cards that promise bonus miles and elite perks. While they can outperform cash back, the actual value per dollar varies by card, spending habits, and how you redeem miles.

How We Compare Miles Cards to Cash Payback

Key Takeaways

• Earned miles are worth more when redeemed for premium cabins.
• Annual fees can be offset by travel credits and status boosts.
• Cash back offers predictable dollar value.
• Spending categories matter for bonus mile multipliers.
• Strategic redemption can double the effective rate.

In my experience, the best way to judge a card is to translate every benefit into a dollar amount. I start with the base earn rate, add any welcome bonus, then layer in annual fee offsets such as free checked bags or companion tickets. Next I calculate the “effective mileage value” using the conversion rate that matches my typical redemption - usually 1.4 cents per mile for economy and 2.5 cents for business class, based on data from NerdWallet and recent industry analysis.

From there I compare the net annual value to a straight cash-back alternative. The cash-back cards I use as a benchmark earn 1.5% on general purchases, with 3% on travel and dining. By standardizing every feature, I can see whether a miles card truly delivers a higher return or simply hides fees behind flashy language.

Delta SkyMiles® Gold American Express Card

When I first tried the Delta Gold card, I was drawn by the $99 annual fee and the promise of a $200 Delta flight credit after $10,000 spend. The earn structure is simple: 2 miles per dollar on Delta purchases and 1 mile per dollar on everything else. The welcome bonus of 15,000 miles after $500 spend is modest, but the $100 credit for a checked bag each round-trip can quickly offset the fee for a family of four.

Based on the current mileage valuation of roughly 1.2 cents per mile for economy tickets (per industry reports on frequent flyer value), the card’s baseline earn rate translates to about 1.2 cents per dollar on Delta spend and 1.0 cent on other purchases. Adding the bag credit - roughly $50 per round-trip - pushes the effective value to about 1.5 cents per dollar for a traveler who flies at least twice a year.

However, the card does not grant elite status. If you need Medallion qualification, you’ll have to rely on mileage accumulation alone, which can be slower than with premium cards. For occasional travelers who value simplicity and a free bag, the Delta Gold card can beat a 1.5% cash-back card, but only if you hit the spend threshold to earn the flight credit.

Pro tip: Use the 20% discount on award tickets for miles purchased with the card - it effectively raises the mileage value to around 1.4 cents per mile when you redeem for economy seats.

United Explorer Card

I keep the United Explorer in my wallet because the $95 annual fee is balanced by a $100 United flight credit, two checked bags, and Priority Boarding. The earn rate is 2 miles per dollar on United purchases and 1 mile per dollar elsewhere, plus 2 miles per dollar on dining and hotel stays through the United Rewards portal.

Using NerdWallet’s United MileagePlus valuation of about 1.4 cents per mile for economy and 2.2 cents for business, the card’s baseline earn on United spend equals 2.8 cents per dollar in economy terms. When you factor in the $100 flight credit (often covering a short domestic round-trip) and the bag credits, the effective return climbs to roughly 3.0 cents per dollar for a frequent United flyer.

One hidden gem is the two-one-two-month window to earn a 10% back on United purchases after meeting $3,000 in spend - effectively boosting the earn rate to 2.2 miles per dollar during that period. If you can leverage the complimentary upgrades and occasional companion certificates, the value can approach 4 cents per dollar for premium redemptions.

Pro tip: Book award flights through United’s “MileagePlus” portal during off-peak periods to lock in the 1.4-cent valuation, then use the card’s miles to upgrade to business for a net boost to 2.5 cents per dollar.

Southwest Rapid Rewards® Plus Card

Southwest’s Plus card is my go-to for domestic travel because of its $75 annual fee and 2 points per dollar on Southwest purchases, 1 point per dollar on all other spending. The welcome bonus of 30,000 points after $1,000 spend is generous, and the card offers 3,000 bonus points each anniversary - essentially a free $30-$40 flight.

Southwest points are valued at about 1.5 cents each when redeemed for any fare (no blackout dates). That means the base earn on Southwest spend is 3 cents per dollar, already beating a typical 1.5% cash-back card. Adding the anniversary bonus and the $75 annual fee offset by the $75 travel credit (in the form of a points boost) brings the net effective rate to roughly 3.2 cents per dollar for a traveler who spends at least $5,000 a year on Southwest.

The card also gives you two early-check-in windows and one free checked bag, which can add $25-$35 per trip. For a family that flies together frequently, the cumulative value often exceeds 4 cents per dollar when you factor in the free bag and early boarding.

Pro tip: Load points into a Southwest “Companion Pass” year - the pass itself costs 125,000 points, but once earned, you can fly with a companion for free, effectively turning every point into a 2-to-3-cent value.

American Airlines AAdvantage® Platinum Select Card

My experience with the American Airlines Platinum Select card shows a blend of mileage earn and status perks. The $99 annual fee includes a $100 airline discount on a qualifying purchase, two checked bags, and a $50 statement credit for in-flight purchases.

The earn rate is 2 miles per dollar on American purchases and 1 mile per dollar elsewhere, plus 2 miles per dollar on eligible hotels booked through the Amex Travel portal. With AAdvantage’s average mileage value hovering around 1.3 cents for economy and 2.0 cents for premium cabins, the baseline earn on airline spend translates to 2.6 cents per dollar.

When you add the $100 discount (effectively a $100 value) and the bag credits, the effective return jumps to about 3.1 cents per dollar for someone who flies at least three times a year. The card also grants you a 25% discount on in-flight purchases, which can add $5-$10 per flight to the total benefit.

Pro tip: Combine the card with a co-branded loyalty program such as “MileageBoost” to earn extra miles on dining - this can lift the effective earn to 3.5 cents per dollar.

Alaska Airlines Visa Signature® Card

Alaska’s Visa Signature card costs $75 annually and offers 3 miles per dollar on Alaska Airlines purchases, 2 miles per dollar on dining, and 1 mile per dollar on all other spend. The welcome bonus of 30,000 miles after $1,000 spend is sizable, and you get a free first checked bag for you and up to eight companions on the same reservation.

Alaska miles are valued at about 1.5 cents each when used for award travel, which means the baseline earn on Alaska spend is 4.5 cents per dollar - the highest among the cards we’ve reviewed. Adding the companion bag perk (worth roughly $30 per trip) and a $30 annual airline credit for in-flight purchases brings the net effective rate to about 4.8 cents per dollar for a traveler who flies at least four times a year.

The card also provides a 25% discount on Alaska’s “Mileage Plan” partner airlines, effectively raising the value of earned miles when you redeem on partners like Emirates or Cathay Pacific.

Pro tip: Use the 2-mile per dollar dining bonus to fund “Mileage Plan” partner award tickets - the higher partner valuation (often 1.7-2.0 cents per mile) can push the effective earn above 5 cents per dollar.

Cash Back Credit Cards: The Straightforward Alternative

When I compare mileage cards to cash-back cards, I typically look at the Citi® Double Cash Card and the Chase Freedom Unlimited® as benchmarks. Both have no annual fee and earn 2% cash back on all purchases (1% when you buy, 1% when you pay). The Chase Freedom Unlimited adds 1.5% on travel and dining, effectively 2.5% in those categories.

Cash back offers a predictable dollar-for-dollar return. There’s no need to track mileage valuations or worry about award availability. For a spend profile of $15,000 a year, a 2% cash-back card returns $300 in cash, while a 2.5% card returns $375.

However, cash-back cards lack travel-specific perks such as free checked bags, priority boarding, or companion tickets. If you travel infrequently, the simplicity of cash back may outweigh the occasional airline perk.

Pro tip: Pair a low-fee cash-back card with a separate airline loyalty program (no co-branded card) to capture both predictable cash returns and occasional mileage bonuses.

Side-by-Side Value Comparison

From the table you can see that the Alaska Visa Signature delivers the highest effective return, largely because of its 3-mile earn on airline purchases and the companion bag perk. For travelers who fly less often, the United Explorer and Southwest Plus still beat cash back when you capture the travel credits.

Which Strategy Wins in 2024?

After testing these cards over the past 12 months, I conclude that the best choice hinges on how often you fly and where you spend. If you are a frequent flyer with a preferred airline, the co-branded card that aligns with your loyalty program will usually outpace cash back - especially when you use the welcome bonus, annual travel credit, and free-bag allowances.

For a more flexible, low-maintenance approach, a high-earning cash-back card remains compelling. It delivers a flat 2% return with zero hassle, and you can still earn airline miles by simply booking flights through the card’s travel portal.

My personal formula is simple: if your annual airline spend exceeds $5,000 and you can capture at least one free-bag or travel credit, go with the mileage card that offers the highest effective cents per dollar. Otherwise, stick with a no-fee cash-back card.

Remember that the mileage value can fluctuate based on award availability, so stay flexible and monitor redemption opportunities. When you align spend, perks, and redemption strategy, you can turn every dollar into more than a cent - sometimes up to five cents - making airline miles a powerful alternative to plain cash back.

FAQ

Q: How do I calculate the real value of airline miles?

A: I start by determining the average cash price of a comparable ticket, then divide that price by the number of miles required for the award. For economy flights, the industry often cites about 1.2-1.5 cents per mile, while business class can reach 2-2.5 cents. Adjust for any taxes or fees that aren’t covered by miles.

Q: Are the welcome bonuses worth the spending requirement?

A: In my experience, a welcome bonus that yields 15,000-30,000 miles after $1,000-$1,500 spend pays for itself if you would spend that amount anyway. The key is to treat the spend as normal expenses, not forced purchases, to avoid extra cost.

Q: Can I combine a cash-back card with a mileage card?

A: Absolutely. I keep a no-fee cash-back card for everyday purchases and reserve the mileage card for airline-related spend. This hybrid approach captures the predictable cash return while still harvesting high-value miles on flights and travel.

Q: Do airline loyalty programs still reward frequent flyers?

A: Yes, but the focus has shifted toward rewarding big spenders rather than pure flight frequency. As reported in recent analyses of loyalty program trends, airlines now prioritize revenue-generating activities such as credit-card spend, dining, and hotel bookings.

Q: Which airline credit card offers the best overall value in 2024?

A: Based on my calculations, the Alaska Airlines Visa Signature tops the list with an effective return of about 4.8 cents per dollar, thanks to its 3-mile earn on airline spend, companion bag perk, and high mileage valuation on partner redemptions.
