Frequently Asked Questions

How do I convert airline miles to dollars?

Multiply the number of miles by the airline's cents-per-mile value. For example, 50,000 Delta miles at 1.2¢ per mile equals $600. This calculator does that math automatically and adjusts for any cash fees charged on award bookings.

How much is 40,000 Delta miles worth in dollars?

At Delta's typical valuation of 1.2¢ per mile, 40,000 SkyMiles are worth approximately $480. However, the actual value depends on which flight you're redeeming them for — a high-demand route can yield better or worse redemption value.

How do I know if using miles is a better deal than paying cash?

Compare the effective cents-per-mile value you're getting from the redemption against the airline's average valuation. If the award flight's effective CPM is higher than the airline's benchmark, it's a good deal to use miles. This calculator makes that comparison for you automatically.

Where can I find the average value of a mile for each airline?

Points valuation guides from sites like The Points Guy and NerdWallet publish monthly estimates. Values typically range from 0.9¢ to 1.8¢ per mile depending on the airline and how you redeem. This calculator uses those benchmark values as defaults.

Are there fees when booking an award flight with miles?

Yes — most airlines charge carrier-imposed surcharges, government taxes, or booking fees even on award tickets. These can range from a few dollars to several hundred dollars on international flights, especially with carriers like British Airways. Always factor these fees into your comparison.

Do you earn miles on flights booked with miles?

Generally, no. Award tickets booked using miles do not earn frequent flyer miles on most airlines. Some programs like Alaska Mileage Plan and Southwest Rapid Rewards may offer partial earning, so check your specific airline's policy.

How do I earn airline miles?

You can earn miles by flying with the airline or its partners, using a co-branded airline credit card for everyday purchases, transferring points from bank rewards programs like Chase Ultimate Rewards or Amex Membership Rewards, and through shopping portals or hotel partnerships.

How do I book a flight using miles?

Log in to your airline loyalty account, search for award availability on the dates you want, select the award fare option, and complete checkout using your miles balance plus any required cash fees. Booking early and being flexible with dates usually unlocks better award availability.
