If you want to earn Delta SkyMiles without paying an annual fee, the Delta SkyMiles Blue American Express Card is one of the simplest ways to get started.
It is the entry-level Delta credit card from American Express, but that does not meabn it is useless. In fact, for casual Delta flyers, restaurant spenders, and people who want to slowly build a SkyMiles balance from everyday purchases, the Delta Blue Amex can be a practical card to keep in your wallet.
The card is not designed for luxury travel perks. You will not get lounge access, a free checked bag, priority boarding, or a Companion Certificate. But if your main goal is simple—earn Delta SkyMiles from Delta purchases, restaurants, and everyday spending—then this card can make a lot of sense.
Let’s break down exactly how to earn SkyMiles using the Delta SkyMiles Blue Amex, how the earning categories work, and how to make the most of the card.
First, Are They Called SkyMiles Points or Miles?
Before we go deeper, let’s clear up a small but common confusion.
Delta’s rewards currency is officially called SkyMiles, and the rewards you earn are usually referred to as miles, not points. Some people casually call them “points,” but in Delta’s program, you are earning SkyMiles.
So when you use the Delta SkyMiles Blue Amex, you are earning Delta miles that can later be used for things like award flights, Pay with Miles, seat upgrades when available, Delta Vacations, and other eligible redemptions.
Quick Look: How the Delta SkyMiles Blue Amex Earns Miles
The earning structure is very simple:
| Purchase Category | Earning Rate |
|---|---|
| Restaurants worldwide, including takeout and delivery in the U.S. | 2X miles |
| Eligible Delta purchases made directly with Delta | 2X miles |
| All other eligible purchases | 1X mile |
| Limit on miles you can earn | No limit |
That simplicity is one of the biggest strengths of the card. You do not need to memorize a long list of rotating categories. You just need to remember three things: Delta, dining, and everything else.
Earn 2X Miles at Restaurants
One of the best everyday earning categories on the Delta SkyMiles Blue Amex is dining.
The card earns 2X miles at restaurants worldwide, including takeout and delivery in the U.S.
This is a very useful category because many people eat out or order food more often than they book flights. Even if you only fly Delta a few times a year, your restaurant spending can help you build your SkyMiles balance little by little.
This category may include purchases like:
- Dining at restaurants
- Takeout orders
- Food delivery in the U.S.
- Cafés and casual dining
- Some bars or food establishments, depending on how the merchant codes the transaction
For example, if you spend $250 per month on restaurants, takeout, or eligible delivery, you could earn:
$250 x 2 miles = 500 SkyMiles per month
Over a full year, that becomes:
500 miles x 12 months = 6,000 SkyMiles per year
That is just from dining. If you spend more on food, the miles can add up even faster.
This is one of the most practical ways to use the card because it connects your everyday lifestyle with future travel. You are not waiting for your next vacation to earn miles. You are earning them while grabbing lunch, ordering dinner, or meeting friends for coffee.
How to Maximize the Restaurant Category
To get the most from the 2X restaurant category, use the card consistently whenever the purchase qualifies as dining.
A good strategy is to make the Delta Blue Amex your default card for restaurants and eligible takeout or delivery purchases. That way, you are not missing easy miles.
You can also stack your earning by enrolling in SkyMiles Dining, Delta’s dining rewards program. SkyMiles Dining is separate from the credit card. When you enroll an eligible card and dine at participating restaurants, you can earn additional SkyMiles through the dining program on top of the miles you earn from your card.
For example, you may earn:
- 2X miles from the Delta SkyMiles Blue Amex
- Additional miles from SkyMiles Dining, if the restaurant participates and your card is enrolled
That means one dining purchase could potentially earn miles in two ways.
The important thing is to check whether the restaurant participates in SkyMiles Dining and make sure the card you use is enrolled in the program. Not every restaurant qualifies, but it is worth checking because it can turn normal meals into extra miles.
Earn 2X Miles on Delta Purchases
The second major bonus category is Delta purchases.
The Delta SkyMiles Blue Amex earns 2 miles per dollar on eligible purchases made directly with Delta.
This is the most obvious way to use the card. If you are booking a Delta flight, buying an eligible Delta purchase, or paying directly through Delta, this card can help you earn extra SkyMiles.
Eligible Delta purchases may include things like:
- Delta flights purchased directly with Delta
- Eligible seat upgrades
- Certain Delta fees or travel-related purchases
- Eligible Delta in-flight purchases, depending on the transaction
The key phrase is made directly with Delta. That usually means purchases through Delta’s official website, app, reservation line, or other direct Delta channels.
If you book through a third-party travel website, online travel agency, or separate booking platform, the purchase may not code as a direct Delta purchase. That could affect whether you earn the 2X Delta rate.
For example, if you buy a $400 Delta ticket directly from Delta and pay with your Delta SkyMiles Blue Amex, you would earn:
$400 x 2 miles = 800 SkyMiles from the card
That is just the credit card earning side. If your ticket is eligible to earn miles as a SkyMiles member, you may also earn miles from flying.
Card Miles vs. Flight Miles: What’s the Difference?
This is an important point.
When you buy a Delta flight with your Delta SkyMiles Blue Amex, there are two possible ways to earn miles:
- Miles from the credit card purchase
- Miles from flying as a SkyMiles member
The card earns miles based on how much you spend with the card. So if you make an eligible Delta purchase directly with Delta, the Blue Card earns 2X miles.
Separately, your Delta SkyMiles account may earn miles from the flight itself if the ticket qualifies. General SkyMiles members typically earn miles based on the eligible cost of the ticket, while Medallion members may earn more depending on their status level.
So if you buy an eligible Delta ticket directly with Delta, you may be earning from both sides:
- The Delta SkyMiles Blue Amex earns miles on the purchase.
- Your Delta SkyMiles account earns miles from the eligible flight.
That is why it is important to always enter your SkyMiles number when booking Delta flights. The credit card earns from payment, but your SkyMiles account earns from the travel activity.
Earn 1X Miles on All Other Eligible Purchases
The Delta SkyMiles Blue Amex also earns 1 mile per dollar on all other eligible purchases.
This applies to purchases that do not fall under the 2X restaurant or 2X Delta categories.
Examples may include:
- Gas
- Groceries
- Phone bills
- Streaming subscriptions
- Online shopping
- Clothing
- Household items
- Drugstores
- Utilities, where cards are accepted
- Everyday errands
This is the “everything else” category. It is not flashy, but it helps you keep earning.
For example, if you spend $1,000 per month on other eligible purchases, you could earn:
$1,000 x 1 mile = 1,000 SkyMiles per month
Over one year, that becomes:
1,000 miles x 12 months = 12,000 SkyMiles per year
That can be meaningful over time, especially if you are also earning from dining, Delta purchases, flights, and partner programs.
There’s No Limit to How Many Miles You Can Earn
Another nice feature of the Delta SkyMiles Blue Amex is that there is no limit to how many miles you can earn on eligible purchases.
That means you do not have to worry about hitting a spending cap in the bonus categories. If you keep making eligible purchases, you can keep earning miles.
This is helpful for people who use the card regularly for dining, travel, and everyday expenses. Whether you spend a little or a lot, your eligible purchases can continue building your SkyMiles balance.
Of course, that does not mean you should overspend just to earn miles. The best way to use any rewards card is to spend only what you can afford to pay off. SkyMiles are valuable, but they are not worth paying high interest charges.
Earn the Welcome Bonus
Another way to earn SkyMiles with the Delta SkyMiles Blue Amex is through the welcome offer.
Welcome offers can change, but the card has recently offered bonus miles after you spend a required amount within the first few months of Card Membership. For example, Delta currently lists an offer of 10,000 bonus miles after spending $1,000 in eligible purchases in the first 6 months.
This can be one of the fastest ways to earn miles with the card.
If you already planned to spend enough on normal purchases, the welcome bonus can give your SkyMiles account an early boost. The key is to meet the spending requirement naturally. Do not buy things you do not need just to chase the bonus.
Good purchases to help meet the spending requirement may include:
- Groceries
- Dining
- Gas
- Phone bills
- Utility bills
- Insurance payments, if card payments are accepted
- Online shopping
- Travel bookings
- Planned household purchases
A welcome bonus is most valuable when it fits into spending you were already going to do anyway.
Use Additional Cards to Earn More Miles
Another useful detail is that eligible purchases made by Additional Card Members can also earn miles for the Basic Card Member’s SkyMiles account.
This can help households earn faster.
For example, if you have an additional card for a spouse, partner, or trusted family member, their eligible purchases can help build the same SkyMiles account connected to the primary card.
Let’s say the Basic Card Member spends $500 per month and the Additional Card Member spends $300 per month on eligible purchases. That is $800 in combined monthly card spending. Over time, the miles can add up faster than if only one person used the account.
Of course, this only works if you are comfortable managing shared card spending. The Basic Card Member is generally responsible for the account, so it is important to set clear expectations with any Additional Card Member.
Stack With SkyMiles Shopping
One smart way to earn more SkyMiles is to use SkyMiles Shopping, Delta’s online shopping portal.
SkyMiles Shopping lets SkyMiles members earn miles when shopping with participating online retailers. The process is usually simple:
- Go to the SkyMiles Shopping portal.
- Sign in with your SkyMiles account.
- Search for the store you want.
- Click through from the portal to the retailer’s website.
- Shop and pay as usual.
If the purchase qualifies, you can earn miles through the shopping portal. Then, if you pay with your Delta SkyMiles Blue Amex, you can also earn miles from the card.
This is called “stacking.”
For example, imagine a store in the SkyMiles Shopping portal offers 3 miles per dollar, and you make a $100 eligible purchase using your Delta Blue Amex.
You could potentially earn:
- 300 miles from SkyMiles Shopping
- 100 miles from the Delta Blue Amex at 1X
That would be 400 total SkyMiles from one purchase, assuming everything tracks and qualifies.
The earning rates in shopping portals can change often, so it is a good habit to check the portal before buying anything online. Even small purchases can earn extra miles if you consistently start through the portal.
Stack With SkyMiles Dining
SkyMiles Dining is another way to build your balance faster.
The Delta SkyMiles Blue Amex already earns 2X miles at restaurants. But if you enroll the card in SkyMiles Dining and eat at participating restaurants, you may earn additional miles through the dining program.
This is a great match because the Blue Card already rewards dining.
Here is how it could work:
- You enroll your Delta SkyMiles Blue Amex in SkyMiles Dining.
- You dine at a participating restaurant.
- You pay with your enrolled card.
- You earn 2X miles from the Delta Blue Amex.
- You earn additional miles through SkyMiles Dining.
That is one of the easiest ways to multiply your dining rewards without doing anything complicated.
The main limitation is that the restaurant must participate in SkyMiles Dining. So it is worth checking the program’s website, especially before dining out in areas with many restaurants.
Link Your SkyMiles Account With Uber
Delta also has a partnership with Uber, allowing SkyMiles members to earn miles on eligible Uber rides and Uber Eats orders after linking accounts.
This is not a credit card benefit by itself, but it can work nicely alongside your Delta Blue Amex.
For example, you may be able to earn SkyMiles from an eligible Uber transaction through the Delta-Uber partnership, and then also earn credit card rewards when paying with your card.
This can be useful for airport rides, premium rides, scheduled rides, or eligible food delivery, depending on current program rules.
The important step is linking your Delta SkyMiles and Uber accounts. If your accounts are not linked, you may miss out on the extra SkyMiles.
Use the Card for Monthly Bills
A practical way to earn more miles is to put predictable monthly bills on the card.
This can include:
- Mobile phone bill
- Internet bill
- Streaming subscriptions
- Insurance payments
- Gym membership
- Software subscriptions
- Utilities, if accepted without high fees
Monthly bills are useful because they happen automatically. Instead of thinking about earning miles every time, you set up the card once and let the miles accumulate.
For example, if you have $300 in monthly eligible bills and subscriptions, that could earn:
$300 x 1 mile = 300 SkyMiles per month
Over a year:
300 x 12 = 3,600 SkyMiles
That may not sound huge, but combine it with dining, Delta purchases, online shopping portals, and welcome bonuses, and the total becomes more meaningful.
One warning: some billers charge processing fees for credit card payments. If the fee is high, it may not be worth using the card. Always compare the fee against the value of the miles you are earning.
Use the Card for Planned Big Purchases
The Delta SkyMiles Blue Amex can also help you earn miles on planned larger purchases.
This may include:
- Appliances
- Electronics
- Furniture
- Travel bookings
- Home repairs
- Gifts
- Event tickets
- School expenses, where cards are accepted
Because the card earns 1X miles on other eligible purchases, large purchases can quickly add miles to your account.
For example, a $1,500 laptop purchase would earn:
$1,500 x 1 mile = 1,500 SkyMiles
That is not a bonus category, but it still helps.
The key word is planned. Do not buy expensive things just to earn miles. But if you already need to make the purchase and can pay the balance in full, using the card can turn that expense into travel rewards.
Use the Card When Traveling Abroad
Since the Delta SkyMiles Blue Amex has no foreign transaction fees from American Express, it can also be useful for international travel.
That means Amex will not charge an extra foreign transaction fee when you use the card outside the U.S. or with foreign merchants.
This can help you keep earning SkyMiles while traveling abroad. Restaurant purchases worldwide can also earn 2X miles, which is great if you enjoy dining during trips.
For example, if you spend $300 at eligible restaurants during an international trip, you could earn:
$300 x 2 miles = 600 SkyMiles
One practical note: American Express acceptance can vary depending on the country, city, and merchant. In many major cities and hotels, it may be accepted. But in smaller restaurants, local shops, or transportation services, you may still want a backup Visa or Mastercard.
Do Not Carry a Balance Just to Earn Miles
This is very important: earning SkyMiles is only worth it if you avoid unnecessary interest charges.
Rewards cards can have high APRs. If you carry a balance and pay interest, the cost of interest can easily be much higher than the value of the miles you earn.
For example, earning 1,000 or 2,000 miles is nice. But if you are paying interest month after month, the rewards are probably not worth it.
The best strategy is simple:
- Use the card for purchases you already planned to make.
- Track your spending.
- Pay the balance in full whenever possible.
- Treat miles as a bonus, not a reason to overspend.
That is how you make the card work for you instead of against you.
Example: How Many SkyMiles Could You Earn in a Year?
Let’s look at a simple example.
Imagine you use the Delta SkyMiles Blue Amex like this each month:
- $300 at restaurants
- $100 on Delta purchases averaged over the year
- $800 on other eligible purchases
Here is how the earning could look:
| Monthly Spending | Category | Earning Rate | Monthly Miles |
|---|---|---|---|
| $300 | Restaurants | 2X | 600 |
| $100 | Delta purchases | 2X | 200 |
| $800 | Other eligible purchases | 1X | 800 |
| Total | 1,600 miles |
At 1,600 miles per month, you could earn:
1,600 x 12 = 19,200 SkyMiles per year
That does not include a welcome bonus, miles from flying, SkyMiles Shopping, SkyMiles Dining, Uber, or other Delta partners.
If you also earn a welcome bonus, use shopping portals, and fly Delta occasionally, your annual mileage total could be much higher.
Best Purchases to Put on the Delta SkyMiles Blue Amex
To earn the most miles with this card, prioritize the categories where it earns best.
The best purchases to put on the Delta Blue Amex include:
- Delta flights booked directly with Delta
- Eligible Delta purchases
- Restaurants
- Takeout in the U.S.
- Food delivery in the U.S.
- International restaurant purchases
- Online purchases through SkyMiles Shopping
- Participating SkyMiles Dining restaurants
- Monthly bills with no extra card fee
- Planned purchases you can pay off in full
The card is especially useful if your spending naturally includes dining and occasional Delta travel.
Purchases That May Not Be Ideal for This Card
The Delta SkyMiles Blue Amex is not always the best card for every purchase.
For example, if another card earns higher rewards on groceries, gas, travel, or everyday spending, that card may be better for those categories. The Blue Card earns only 1X miles outside restaurants and Delta purchases.
Also, if a merchant charges a high fee to use a credit card, it may not be worth paying that fee just to earn miles.
The card is best used strategically. Use it where it earns well, where it helps you stack SkyMiles, or where you value the convenience of earning Delta miles.
What Can You Do With the SkyMiles You Earn?
Once you earn SkyMiles, you can use them in different ways through Delta.
Common redemption options include:
- Award flights with Delta
- Eligible partner airline flights
- Pay with Miles on Delta.com
- Seat upgrades, when available
- Delta Vacations and other eligible travel options
One of the Blue Card’s useful features is Pay with Miles, which lets eligible Card Members take up to $50 off the cost of a flight for every 5,000 miles redeemed when booking on Delta.com.
This gives you flexibility. You do not always need enough miles for a full award ticket. You can use miles to reduce the cash cost of a Delta flight.
For example:
- 5,000 miles = up to $50 off
- 10,000 miles = up to $100 off
- 20,000 miles = up to $200 off
This can be helpful for casual travelers who are slowly building a SkyMiles balance.
Do SkyMiles Expire?
Another helpful thing about Delta SkyMiles is that they do not expire under Delta’s mileage expiration policy.
That is good news for casual travelers. You do not have to rush to redeem your miles just because you have not flown recently.
However, miles can still change in value over time because loyalty programs can update award pricing, fees, and rules. So while your miles do not expire, it is still smart to use them when you find a redemption that makes sense for your travel plans.
Is the Delta SkyMiles Blue Amex Good for Earning Miles?
Yes, if you understand what the card is built for.
The Delta SkyMiles Blue Amex is good for earning miles if you want:
- A no-annual-fee Delta card
- Simple earning categories
- 2X miles on Delta purchases
- 2X miles at restaurants
- 1X miles on everyday eligible purchases
- No cap on miles earned
- Access to Pay with Miles
- A way to slowly build SkyMiles without paying an annual fee
It is especially useful for casual Delta flyers who eat out regularly and want a low-commitment way to earn travel rewards.
However, it may not be the best choice if you fly Delta often and want premium benefits. If you regularly check bags, want priority boarding, or want more Delta travel perks, you may want to compare it with the Delta SkyMiles Gold, Platinum, or Reserve cards.
Final Thoughts
The Delta SkyMiles Blue American Express Card is a simple but useful way to earn Delta SkyMiles from everyday spending.
You earn 2X miles at restaurants, including takeout and delivery in the U.S. You earn 2X miles on eligible Delta purchases made directly with Delta. You earn 1X miles on all other eligible purchases. And there is no limit to how many miles you can earn.
The best way to maximize the card is to use it for dining, Delta purchases, online shopping through SkyMiles Shopping, participating restaurants through SkyMiles Dining, and planned everyday expenses you can pay off in full.
It is not the most premium Delta card, but it does not need to be. For a no-annual-fee card, it gives casual travelers a straightforward path to earning SkyMiles—one meal, one bill, one Delta trip, and one everyday purchase at a time.
