Hilton Honors is currently notifying members via a pop-up that, starting May 31, 2025, the program will no longer partner with Asiana Airlines for points transfers. This means that if you want to transfer Hilton points to Asiana Airlines miles, you must complete the transfer before that date; otherwise, this option will no longer be available.
The value of transferring points between Hilton and Asiana has never been particularly strong. The transfer ratio is 10:1, meaning transferring 10,000 Hilton points yields only 1,000 Asiana miles, so this has really only been useful for topping off an account.
