What Delta credit cards offer and who they suit
Delta offers three co-branded cards through American Express: the Blue Business, Blue Cash, and Reserve. Each one earns miles on Delta purchases and everyday spending, but they differ in annual fees, sign-up bonuses, and perks like checked baggage allowances and priority boarding. The Blue Business and Blue Cash have no annual fee; the Reserve costs $550 per year and includes a $100 annual Delta credit that offsets part of that cost.
These cards make sense if you fly Delta regularly and want miles to accumulate faster than you would with a non-airline card. They also work if you want to consolidate your airline and everyday spending into one program. If you fly multiple carriers or rarely take trips, a general rewards card might give you more flexibility.
Key Takeaways
- Delta's no-annual-fee cards (Blue Business and Blue Cash) earn 2 miles per dollar on Delta purchases and 1 mile per dollar on other spending, with no ongoing cost.
- The Delta Reserve card costs $550 yearly but includes a $100 annual Delta credit, priority boarding, checked baggage for you and a companion, and higher earning rates on Delta and restaurant purchases.
- Sign-up bonuses typically range from 30,000 to 75,000 miles depending on the card and current offer, and you must meet a spending threshold within a set timeframe to receive them.
- All three cards earn miles that do not expire as long as your account remains open and you have account activity at least once per year.
- The best card for you depends on how often you fly Delta, whether you value premium perks, and whether the annual fee nets out against the credits and benefits you will actually use.
Comparing the three Delta American Express cards
The Blue Business and Blue Cash are nearly identical in structure. Both have zero annual fee, earn 2 miles per dollar on Delta purchases and 1 mile per dollar on everything else, and come with a checked bag free on Delta flights (for the cardholder only). The main difference is that the Blue Business is designed for business owners and sole proprietors, while the Blue Cash is for personal use. American Express may ask for business documentation when you explore for the Blue Business, but both cards report to personal credit bureaus.
The Delta Reserve is the premium tier. It costs $550 per year but includes a $100 annual Delta credit (applied automatically to your Delta account each calendar year), which brings the net cost to $450. You also get a free checked bag for you and one companion on the same reservation, priority boarding, and a 10% mileage bonus on all miles earned that year. The Reserve earns 3 miles per dollar on Delta purchases and restaurants, and 1 mile per dollar on other spending.
None of the three cards charge foreign transaction fees, which matters if you book international flights or use the card abroad. All three allow you to transfer miles to Delta's partners, though the partner list is smaller than some other airline programs.
Sign-up bonuses and how to evaluate them
Delta rotates its sign-up offers, so the bonus you see today may differ from next month's offer. Historically, the Blue Business and Blue Cash have offered bonuses in the range of 30,000 to 50,000 miles, while the Reserve has offered 50,000 to 75,000 miles. Each bonus requires you to spend a set amount—often $1,000 to $3,000—within three months of opening the account.
To decide whether a bonus is worth pursuing, think about whether you can meet the spending requirement without changing your normal habits. If you spend $2,000 per month anyway, a $1,000 threshold is straightforward; a $5,000 threshold means you would need to accelerate spending or manufacture purchases, which defeats the purpose. Once you have the bonus, compare the ongoing value: a no-fee card earning 2 miles per dollar on Delta is worth keeping if you fly Delta at least once or twice per year, since the miles themselves have value even if you do not use the card for other purchases.
The Reserve's higher bonus is offset by the annual fee. You break even on the $550 fee if you use the $100 credit and earn enough miles to justify the higher earning rates. If you fly Delta fewer than four or five times per year, the no-fee cards are usually the better choice.
Perks that come with each card
The Blue Business and Blue Cash include one free checked bag on Delta flights (for the cardholder), priority boarding (Group 2 instead of Group 3 or later), and a 5% mileage bonus on all miles earned during the year. These perks alone can save you $35 per flight in baggage fees if you check a bag regularly.
The Reserve adds significant value if you use it: a free checked bag for a companion on the same reservation, a $100 annual Delta credit that covers most of a domestic round-trip ticket, and a 10% mileage bonus instead of 5%. You also get access to Delta Sky Club lounges (up to 10 visits per year, then $39 per visit after that), which can be valuable if you have long layovers or want to work in a quieter space before your flight.
All three cards include purchase protections like extended warranty coverage and trip cancellation insurance. The Reserve's protections are slightly broader, but the differences are minor for most travelers. Read the full terms on American Express's website to see what is covered under your specific card.
How Delta miles work and what they are worth
Miles earned on any Delta card do not expire as long as your account stays open and you have at least one account activity per year (a purchase, a flight, a transfer, or even a phone call to customer service counts). This means you can accumulate miles over time without pressure to use them when ready.
The value of a mile varies depending on how you redeem it. A domestic round-trip flight might cost 25,000 to 50,000 miles depending on the route and how far in advance you book. An international flight can range from 60,000 to 150,000 miles. You can also transfer miles to Delta's partners (like Virgin Atlantic or Air France), though the transfer rate is usually 1:1 and partner awards often require more miles than Delta's own flights.
Miles are most valuable when you redeem them for flights you would otherwise pay cash for. If you fly Delta once per year and earn 20,000 miles from the sign-up bonus plus another 10,000 from regular spending, you may have enough for a domestic award flight within a year or two. If you do not fly Delta at all, the miles sit unused and the card becomes a drag on your wallet.
Deciding between a Delta card and other airline or rewards cards
A Delta card makes the most sense if you have a home airport served by Delta, fly the airline at least a few times per year, or live in a city where Delta is a major carrier. If you fly multiple airlines equally, a general rewards card (like the American Express Gold or Chase Sapphire Preferred) gives you more flexibility because the points or miles can be transferred to any airline partner.
If you fly Delta only occasionally—once every two or three years—the sign-up bonus might be your only real benefit, and the card becomes a dormant account. In that case, a no-fee card is still worth keeping because it costs nothing and the miles do not expire. A premium card like the Reserve only makes sense if you fly Delta frequently enough to use the lounge access and checked baggage perks regularly.
Consider also whether you want to consolidate your rewards into one program or spread them across multiple cards. Some people prefer one card that earns miles on everything; others prefer a portfolio approach where they use different cards for different spending categories. There is no single right answer—it depends on your travel patterns and how much time you want to spend managing rewards.
Frequently Asked Questions
Can I earn miles on a Delta flight booked with a credit card from another airline?
Yes. You earn miles based on your ticket price and frequent flyer status, not on which credit card you use to pay. However, you will only earn the credit card bonus miles if you use that specific card to purchase the ticket. If you book a Delta flight with a United card, you earn United miles from the card but Delta miles from the flight itself.
What happens to my miles if I close the card?
Your miles stay in your Delta account and do not disappear when you close the card. However, if your entire Delta account becomes inactive (no flights, no purchases, no transfers) for 12 months, Delta may close the account and forfeit the miles. Keeping at least one Delta card open or taking one Delta flight per year prevents this.
Is the $100 Delta credit on the Reserve card automatic?
Yes. American Express applies the $100 credit to your Delta account automatically each calendar year, as long as your Reserve card remains open. You do not have to request it or meet any spending threshold. The credit appears in your Delta account within a few days of your card anniversary.
Can I get a sign-up bonus if I already have a Delta card?
American Express has rules about how often you can earn a bonus on the same card. Generally, you must wait a certain period (often 24 months) after closing a card before you can earn a bonus on that card again. You can hold multiple Delta cards at once and earn a bonus on each one if you meet the spending requirements, but check American Express's current rules before explore.
Do I earn miles on the annual fee itself?
No. Annual fees do not earn miles. However, the $100 Delta credit on the Reserve card effectively reduces your net annual fee to $450, and the miles you earn on everyday spending and Delta purchases should more than offset the remaining cost if you use the card regularly.
