How much Delta miles are worth depends on how and when you redeem them. For flight tickets, you can, on average, expect to get 1.4 cents to 1.5 cents per mile, although you may do better or worse in some cases. Once you join the Delta frequent flyer program, you earn SkyMiles on all eligible flight tickets booked with Delta and its partner airlines. You can also earn miles through the program’s partner merchants and by using co-branded Delta SkyMiles credit cards. If needed, you may even buy Delta miles.
When it comes to how to use Delta SkyMiles, you may redeem them for flight tickets with Delta and its partner airlines, Delta Vacation packages, seat upgrades, Delta Sky Club membership, gift cards or SkyMiles Experiences. Gifting or transferring your miles to other Delta SkyMiles members is an option, as is donating them to charity.
