How to Purchase Miles With a Frontier Airlines Credit Card

When you open or use a Frontier Airlines credit card, you gain the ability to buy miles directly through the airline's program. But "purchasing miles" works differently than simply using your card for everyday spending—and whether it makes financial sense depends entirely on your specific travel timeline and redemption plans. 📈

What Purchasing Miles Actually Means

Purchasing miles refers to buying Frontier Airlines frequent flyer currency directly from the airline, typically through a branded credit card offer or promotion. This is distinct from earning miles through card spending or flights. When you purchase miles, you're paying cash (charged to your card) to add a bulk amount of miles to your account immediately.

Airlines offer these opportunities because buying miles—especially during promotions—generates revenue and can help members reach redemption goals faster than earning alone would allow.

How It Works With a Frontier Card

Most Frontier Airlines credit cards include periodic opportunities to buy miles at promotional rates. These typically appear as:

• Sign-up offers bundling bonus miles with card approval
• Targeted promotions mailed or emailed to cardholders offering discounted per-mile costs
• Direct purchase options through the airline's website (available to credit card members)

When you participate, you're charged a specific amount per mile. The cost per mile varies—sometimes heavily discounted during promotions, sometimes standard pricing when no offer is active.

The Key Variables That Affect Your Decision 🎯

Whether buying miles makes sense depends on:

When Buying Miles Might Make Sense

Purchasing miles is most appealing if you:

• Have an upcoming trip (within weeks or months) and need a specific number of miles to complete a redemption
• Found a promotional rate that costs less per mile than the dollar value of the flight would be
• Have already verified that award availability exists on your intended route
• Value convenience and certainty over optimizing every dollar spent

When It Usually Doesn't

Buying miles often doesn't work if you:

• Are paying standard rates (not a promotion) and haven't done the math against cash ticket prices
• Don't have a concrete trip planned and are speculating on future value
• Could earn those miles through regular card spending within your timeline
• Are uncertain whether award seats will be available when you're ready to book

The Math You'll Need to Do Yourself

There's no universal "good deal" for purchasing miles. You have to compare:

1. Cost of buying miles (number of miles needed × promotional rate per mile)
2. Cost of a cash ticket for the same flight
3. Earnings rate on your card if you charged that amount instead (miles earned + any sign-up bonus)

Only you can weigh these numbers against your specific trip and timeline.

Important Limitations

• Award availability isn't guaranteed. Buying miles doesn't reserve a seat; you still need to find available award inventory when you're ready to book.
• Miles can expire if your account becomes inactive, though credit card activity typically prevents this.
• Promotions change frequently. The rate you see today won't necessarily be available next month.
• Frontier's award chart and policies may change. The number of miles required for a flight can shift.

The right choice depends on your travel plans, not on purchasing miles being inherently good or bad. Compare your specific options before deciding.
