Members of Korean Air’s frequent-flyer programme, Skypass, will no longer be able to accrue miles through spending on hotels operated by Hilton.

A notification published on the airline’s website has stated that the two companies will terminate their loyalty partnership from April 2, 2018.

The termination applies to all brands under the Hilton umbrella, including its flagship Hilton Hotels and Resorts brand as well as Waldorf Astoria, Conrad, Canopy, the Curio Collection, Doubletree by Hilton, and the Tapestry Collection, among others.

Currently, Skypass members are able to accrue one mile for every US$1 spent on rooms at Hilton properties.

Members can still accrue miles through stays with Accorhotels, Marriott, Starwood, IHG and Hyatt, though miles accrual occurs at varying rates across the brands.

A spokesperson for Korean Air declined to comment as to the reason for the partnership’s termination.;
