To cancel the Frontier Airlines credit card without losing your miles, call Barclays Bank Delaware at 866-839-2435 to close the account, but first understand this: your Frontier Miles only stop expiring while the card is open.1Frontier Airlines. Terms and Conditions The moment you close, the standard expiration policy takes over, and you’ll need at least one qualifying earning activity every 12 months to keep the miles alive.2Frontier Airlines. Frontier Miles Activity Plan for that activity before you dial, and the miles you’ve built up stay yours.
Protect Your Miles Before You Cancel
Your Frontier Miles live in your Frontier Miles loyalty account, not on the credit card itself, so they don’t disappear the day you cancel. What changes is the protection. While the card is open and in good standing, miles don’t expire at all. Once the account closes, the 12-month activity clock starts.
Qualifying activity includes booking flights on FlyFrontier.com or earning miles through Frontier’s partners. Redeeming miles does not count. If you already have a Frontier trip on the calendar within the next year, you’re covered. If not, either burn the miles on an award booking before you cancel, or line up a partner earning activity you’ll actually complete within 12 months of closing the card.
Pay Off the Full Payoff Balance
Check your most recent statement, but don’t assume that number is what you owe today. Barclays calculates interest on an average daily balance method, and interest compounds daily, so new interest accrues between the statement date and the day you pay.3Barclays. Addendum to the Cardmember Agreement Ask the representative for the payoff balance, which reflects interest through the current day, and pay that amount.
Closing with a few dollars still on the card can trigger additional interest and a late fee the following month. An unpaid balance on a closed account still gets reported to the credit bureaus. Before you complete the cancellation, confirm with the agent that the balance reads zero.

Getting the $99 Annual Fee Refunded
The Frontier card carries a $99 annual fee, and timing matters. The Barclays cardmember agreement allows new cardholders to close within 30 days of account opening without owing the annual fee, provided they haven’t made any purchases.5Barclays. Standard Credit Agreement For existing cardholders who see the fee post on a renewal statement, the general practice is the same window: contact Barclays within about 30 days of the fee posting to request a refund. Wait longer and Barclays won’t offer a full or prorated refund.
Set a reminder a few weeks before your card anniversary so you can decide before the fee hits. If it’s already posted, call right away.
Consider a Product Downgrade Instead
Canceling eliminates a line of credit. A product change, sometimes called a downgrade, switches you to a different Barclays card with no annual fee while keeping the same account number and history. Barclays doesn’t widely advertise this option, and frontline representatives sometimes suggest closing and reapplying for a new card instead. If you’re told a product change isn’t available, ask to speak with an account specialist.
A downgrade isn’t guaranteed. Barclays may limit which cards are available for a switch, and eligibility can depend on your account standing. If preserving your credit history matters to you, ask before you cancel outright.
What Cancellation Does to Your Credit Score
Closing the card reduces your total available credit. If you carry balances elsewhere, losing this credit line pushes your overall utilization ratio higher. Keeping utilization below 30 percent is a common guideline, and lower is better. Add up the balances on your other cards and divide by the total credit limits on those remaining cards; if that number jumps above 30 percent without the Frontier card’s limit, pay down balances before canceling.
Account age matters too. A closed account in good standing stays on your credit report for up to 10 years and continues aging during that time, so the impact on your average account age isn’t immediate. After the 10-year mark, the account drops off entirely, which can shorten your credit history. If the Frontier card is one of your oldest accounts, a product downgrade preserves that history indefinitely.
Confirm the Account Is Closed
Don’t assume the cancellation went through just because you asked. Request written confirmation from Barclays. Check your next billing statement to make sure the balance reads zero and no new fees posted after the closure date. If anything looks off, contact Barclays with your confirmation number.
Within 30 to 60 days, pull your credit report from one of the three major bureaus and verify the account shows as closed with no missed payments and no outstanding balance. Then check your Frontier Miles account, and make sure your plan for a qualifying activity within the next 12 months is still on track.
