In 2026, you can "give away" airline miles, but the process usually involves a transfer fee that can be quite high. Most major loyalty programs, such as Delta SkyMiles and American Airlines AAdvantage, allow you to transfer miles from your account to another member's account, but they often charge around $0.01 to $0.015 per mile, plus a processing fee. Because of these costs, it is often more "value-efficient" to book a flight for someone else using your miles directly from your own account; this is usually free and only requires you to enter their name as the passenger. Another popular way to "give" miles in 2026 is through charitable donations; many airlines allow you to donate your expiring or unused miles to organizations like Make-A-Wish or disaster relief groups. While you cannot "sell" your miles on the open market (which is a violation of the contract and can lead to your account being banned), gifting them to friends or family for a specific trip remains a versatile way to share the benefits of your frequent flyer status.
