What Northwest Airlines Membership Actually Offers

Northwest Airlines stopped flying in 2010 after merging with Delta Air Lines. If you hold a Northwest Airlines credit card or membership account, you likely have one of two situations: an old rewards card that still works under Delta's system, or an account that needs to be migrated or closed.

The card itself may still be active in your wallet, but the rewards program behind it — Northwest WorldPerks — was absorbed into Delta SkyMiles when the airlines merged. This means your points, your card benefits, and your account status all transferred to Delta's program, whether you took action or not.

If you're trying to understand what you actually have, the first step is logging into your account or calling the card issuer to confirm whether your card is still open and what program it's connected to now.

Key Takeaways

  • Northwest Airlines merged with Delta in 2010, and all Northwest WorldPerks accounts and rewards were transferred to Delta SkyMiles automatically.
  • If you still have a Northwest Airlines credit card, it likely earns Delta SkyMiles points rather than Northwest points, though the card itself may still function.
  • Your old Northwest points did not disappear — they converted to Delta SkyMiles at a set rate during the merger transition period.
  • To access your current rewards balance and card benefits, you need to log into Delta's website or contact Delta customer service, not Northwest.

What Happened to Your Northwest WorldPerks Account

When Northwest and Delta merged in 2010, every Northwest WorldPerks member received a Delta SkyMiles account. The conversion was automatic — you did not have to sign up or transfer anything yourself. Your account number changed, but your points balance converted using a formula Delta published at the time.

If you had elite status with Northwest (like Silver Elite or Gold Elite), that status transferred to Delta as well, though the names and benefits changed to match Delta's tier system. The exact conversion depended on how many miles you had and what tier you held.

The key thing to know: your points did not vanish. They moved to a different program with different rules, different redemption rates, and different ways to earn and spend them.

How to Find Your Current Rewards and Card Status

Start by visiting Delta's website and logging in with the email address you used for your Northwest account. If you remember your old WorldPerks number, that can help, but Delta's system should recognize your email address from the merger records.

If you cannot log in, call Delta SkyMiles customer service at the number on the back of your card (if you still have it) or visit delta.com and use their "Forgot Password" tool. Have your old Northwest account number handy if you can find it — it will speed up the process.

Once you're in, you'll see your current SkyMiles balance, your card benefits, and whether your card is still active. If the card is closed, you'll see the date it was closed and the reason. If it's still open, you can see what rewards rate it earns and what annual fee applies.

Understanding Your Card Benefits Under Delta

The specific benefits on your card depend on which Northwest card you originally held and when it was issued. Some older Northwest cards were converted to Delta co-branded cards with updated benefits; others were straightforward closed as the merger completed.

Common benefits on Delta co-branded cards include checked baggage waivers, priority boarding, seat upgrades, and earning bonus miles on Delta purchases. The exact perks vary by card tier — a Delta Reserve card offers different benefits than a Delta Blue card, for example.

Your annual fee, if you have one, is now charged by Delta and appears on your credit card statement. You can cancel the card at any time by calling the card issuer, though doing so will close your account and prevent you from earning more miles on that card.

What Happens If Your Card Was Closed

Many Northwest cards were closed during or shortly after the merger. If yours was, you would have received a notice from the card issuer explaining the closure and giving you a important date to redeem any remaining points or transfer them to another account.

If you did not act by that important date, your remaining points may have been forfeited. However, some cardholders were able to contact Delta after the fact and recover points if they could prove they held the card. The window for this has largely closed, but it's worth asking if you believe you had a balance.

If your card was closed and you want to continue earning miles, you can open a new Delta co-branded card through the card issuer's website. This is a separate process and will involve a credit check.

Redeeming Miles and Using Your Account

Once you're logged into your Delta SkyMiles account, you can see what your miles are worth and what you can redeem them for. Delta miles can be used for flights, seat upgrades, checked baggage fees, and other travel-related purchases.

The redemption rate varies depending on what you're buying and when you're flying. A flight that costs 25,000 miles on one date might cost 30,000 miles on another, depending on demand. This is called dynamic pricing, and it means the value of your miles changes based on what you're trying to book.

You can also transfer miles to Delta's airline partners or use them to purchase gift cards and other merchandise, though these options typically offer lower value than booking flights directly.

If You Want to Close Your Account

If you no longer want to hold a Northwest or Delta card, you can close it by calling the card issuer. Before you do, consider redeeming any remaining miles, since closing the account does not automatically give you access to those miles afterward.

Your SkyMiles account itself does not close when you close the card — the account and the card are separate. You can keep your SkyMiles account open indefinitely, even without an active card, as long as you have account activity (like earning or redeeming miles) at least once every 24 months. If you go longer than that without activity, Delta may close the account and forfeit any remaining miles.

If you want to keep your miles but close the card, make sure you have a way to earn miles without the card — for example, by flying Delta directly or using a partner earning opportunity.

Frequently Asked Questions

Can I still use my old Northwest Airlines credit card?

If your card is still active, yes — it will work like any other credit card and will earn Delta SkyMiles on purchases. If it was closed during the merger, no. You can check the status by logging into your account online or calling the card issuer.

What happened to my Northwest miles?

They converted to Delta SkyMiles automatically during the merger. The conversion rate was set by Delta and varied based on how many miles you had. You can see your current balance by logging into your Delta SkyMiles account.

How do I contact customer service about my old Northwest account?

Contact Delta SkyMiles customer service, not Northwest — Northwest no longer operates. Call the number on the back of your card or visit delta.com. Have your old Northwest account number ready if you have it.

Can I transfer my miles to someone else?

Delta allows mile transfers to other SkyMiles members, though there may be a fee. Log into your account and look for the transfer option, or call Delta customer service to ask about the current policy and cost.

What if I lost my old Northwest card and want to access my miles?

You do not need the physical card to access your miles. Log into your Delta SkyMiles account online using your email address, or call Delta customer service. They can verify your identity and help you redeem miles or request a replacement card.
